classes/controllers/FrmStylesController.php (2)
806-821: LGTM — Backward-compatible API extension.The
extra_argsparameter with defaults maintains backward compatibility while enabling flexible customization of the CSS editor. The PHPMD warnings about unused variables are false positives — these variables ($show_errors,$custom_css,$heading,$textarea_params) are used in the includedcustom_css.phptemplate.Note: The
$messageparameter appears genuinely unused in this method. Consider either using it or removing it from the signature if it's not needed.
878-887: Consider escaping the$idin the inline JavaScript.While
$idis currently developer-controlled (defaulting to'frm_codemirror_box'), usingesc_js()would be a defensive practice for the JavaScript context:wp_add_inline_script( 'code-editor', sprintf( 'jQuery( function() { window.%s_wp_editor = wp.codeEditor.initialize( \'%s\', %s ); } );', - $id, - $id, + esc_js( $id ), + esc_js( $id ), wp_json_encode( $settings ) ) );This protects against potential XSS if
$idever originates from user input in future refactors.js/src/admin/styles.js (1)
38-53: Consider using the retryInterval from cssEditorOptions.Line 47 hardcodes the retry interval as
500in thesetTimeoutcall, butthis.cssEditorOptions.retryIntervalis already defined with the same value. Using the property would make the retry interval configurable in one place.Apply this diff:
setTimeout( () => { this.cssEditorOptions.retryCount++; this.initCustomCSSEditorInstance(); - }, 500 ); + }, this.cssEditorOptions.retryInterval );

js/frm_testing_mode.js (1)
1-2: Minified bundled file should not be manually reviewed; verify the build process.This file appears to be a minified/bundled JavaScript output, not source code. The static analysis warnings (switch fallthrough, label/variable conflicts, function reassignments) are expected artifacts of minification and not indicative of actual defects.
Key concerns:
- Manual review is impractical: Minified code is compressed and unreadable, making line-by-line review error-prone and ineffective.
- Build artifacts should not be versioned: Bundled/minified files are typically generated during the build process and should not be committed to the repository.
Recommendations:
- Verify whether a source file (e.g.,
js/src/frm_testing_mode.js, as suggested by the relevant code snippets) exists. If so, include the source in the PR diff for review instead.- Exclude bundled/minified files from version control using
.gitignoreand regenerate them as part of the build pipeline.- Ensure the build process is documented and automated so minified outputs are consistent and reproducible.
Please verify: (1) whether
js/src/frm_testing_mode.js(source) exists and should be included in this PR, (2) the role ofjs/frm_testing_mode.js(is it generated or manually maintained?), and (3) whether bundled files should be included in future PRs.js/addons-page.js (1)
1-1: Minified bundle cannot be meaningfully reviewed without source maps.These are bundled/minified assets generated by a build process. To properly review changes, please provide either:
- Source map references
- Unminified source code from
js/src/directory- Build configuration details
Per the AI summary, these changes appear to be formatting-only with no behavioral changes, but this cannot be verified from minified code alone.

1-2: Minified build artifact — no source-level review applicable.This is a bundled/minified output file. The static analysis warnings (switch fallthrough, throw in finally, use before declaration, function reassignment) are false positives generated by the bundler's transpilation of generators and async/await patterns. These are expected in minified Babel/Webpack output.

83-84: LGTM — Helper instantiation is appropriate.Instantiating
FrmCssScopeHelperonce before the loop is efficient, avoiding repeated instantiation inside the foreach.
262-264: LGTM — Consistent with existingcustom_csshandling.CSS fields require special characters (
{,},;, etc.) that would otherwise be stripped. Excludingsingle_style_custom_cssfromstrip_invalid_charactersis correct and consistent with howcustom_cssis already handled.
756-758: LGTM — Sensible defaults for the new settings.The opt-in pattern (
enable_style_custom_cssdefaulting tofalse) and empty string for CSS content are appropriate defaults.js/formidable_blocks.js (1)

classes/helpers/FrmCssScopeHelper.php (4)
1-6: LGTM — Well-structured CSS scope helper.The class provides clean, focused functionality for CSS scoping with
nest()andunnest()operations. Good separation of concerns.
16-89: Well-implemented CSS nesting with proper edge case handling.The implementation correctly:
- Strips comments before processing
- Handles
@keyframeswithout nesting (as keyframe percentages aren't selectors)- Recursively processes nested at-rules like
@media- Handles comma-separated selectors
One consideration: if the input CSS is malformed (e.g., unclosed braces),
find_matching_brace()returns$length - 1, which may produce unexpected output. However, for user-provided CSS, this graceful degradation is acceptable.
99-173: LGTM — Correctly reverses the nesting operation.The
unnest()method properly handles:
- Selectors that have the prefix (removes it)
- Selectors without the prefix (preserves them unchanged)
- Recursive processing for nested at-rules
216-252: Robust brace matching with string-awareness.Good implementation that correctly handles:
- Nested braces (level tracking)
- String literals (avoids false positives from braces in
content: "{")- Escaped quotes within strings
classes/controllers/FrmStylesController.php (1)
831-835: LGTM — Clean extension for per-style custom CSS.The logic correctly checks both the enable flag and content presence before returning the single style's custom CSS, falling through to the global CSS logic otherwise.

18-24: LGTM! CodeMirror styling is appropriate.The
!importantdeclarations are necessary here to override CodeMirror's default styles, and scoping to.frm-style-componentprevents unintended side effects elsewhere.js/admin/style.js (1)
1094-1107: LGTM! Reset function is well-guarded.The function properly checks for element existence before manipulation and integrates cleanly into the existing reset flow.
classes/views/styles/custom_css.php (3)
8-8: LGTM! Dynamic heading enables flexible messaging.Using a variable for the heading allows callers to customize the message, improving reusability.
12-14: LGTM! Strict comparison is appropriate.Using strict equality (
===) for the boolean check is a best practice in PHP.
16-20: The review comment is incorrect—$textarea_paramsis always initialized before use.The controller method
FrmStylesController::custom_css()(lines 17–20) initializes$textarea_paramswith a default value before including the view file. The conditional block in the view (lines 16–18) only optionally adds a'class'key to an array that is guaranteed to exist. No undefined variable warning will occur.// In controller (lines 17-20): $textarea_params = ! empty( $extra_args['textarea_params'] ) ? $extra_args['textarea_params'] : array( 'name' => 'frm_custom_css', 'id' => $id, ); // Then the view is included with $textarea_params already in scopeclasses/views/styles/_quick-settings.php (2)
229-249: LGTM! Toggle control is well-integrated.The Custom CSS toggle is properly wired with appropriate labels, ARIA attributes, and checked state handling.
274-285: LGTM! Style class display with copy functionality.The style class display shows the scoped class name with a copy icon, providing good UX for users who need to reference the class name.
js/src/admin/styles.js (3)
12-18: LGTM! Properties are well-defined.The new properties support the CSS editor instance management and retry logic appropriately.
163-176: LGTM! Clipboard API guards are robust.The function properly checks for clipboard API availability before attempting to use it and handles multiple copy labels correctly.
178-187: LGTM! Toggle visibility is straightforward.The function correctly toggles the editor visibility based on the checkbox state with proper guards for element existence.

There was a problem hiding this comment.
Fix hardcoded style class name.
Line 256 uses a hardcoded class name 'frm_style_formidable-style-8' in the unnest() call. This should dynamically reference the current style's class name to work correctly across all styles.
Apply this diff to fix the issue:
- $custom_css = $css_scope_helper->unnest( $custom_css, 'frm_style_formidable-style-8' );
+ $custom_css = $css_scope_helper->unnest( $custom_css, 'frm_style_' . $style->post_name );📝 Committable suggestion

In classes/views/styles/_quick-settings.php around lines 251 to 273, the call to
$css_scope_helper->unnest() uses a hardcoded class name
'frm_style_formidable-style-8'; replace that with the current style's class name
built dynamically (for example $class = 'frm_style_' . $style->post_name) and
pass $class to unnest so the scope helper uses the actual style class for the
current $style.

CSS injection attack via textContent in style element JavaScript security
<web_search_result>
Short answer
Yes — writing attacker-controlled text into a <style> element (e.g. style.textContent = userInput) is a CSS‑injection sink. Injected CSS can change page behavior, load attacker URLs (background-image/@import) and, in many cases, exfiltrate page data (using attribute/value selectors, :checked/:hover tricks, etc.). Treat inline stylesheet sinks like inline script: never put untrusted input there. [1][2][3][4]
Why it’s dangerous (brief)
- Injected CSS can hide/overlay UI (phishing, clickjacking) or run legacy engines’ features (IE expression()). [2]
- CSS value/attribute selectors and generated-image requests let an attacker probe element values character‑by‑character and cause the browser to fetch attacker URLs — yielding data exfiltration. (Multiple public PoCs and analyses show this technique.) [3][4]
- Style injection is distinct from traditional JS XSS but can reach similarly serious outcomes when combined with resource fetching or permissive CSP. [2][5]
How browsers / CSP affect this
- A good Content Security Policy that disallows inline styles (no style-src 'unsafe-inline') and uses nonces/hashes for approved inline styles reduces risk; conversely, allowing 'unsafe-inline' or permitting external CSS from attacker-controllable origins enables exploitation. Note that some CSSOM APIs (insertRule/cssText) are also relevant to CSP rules. [1][5]
Practical mitigations (do at least one + preferred stack)
- Never set style.textContent (or innerHTML) from untrusted strings. Only inject developer‑controlled CSS.
- If you must accept user CSS, sandbox it: isolate in an iframe with a different origin and restrictive CSP, or parse & strictly whitelist allowed properties/values (very hard to do correctly). [2][3]
- Use a strict CSP: disallow inline styles (omit 'unsafe-inline'), use style-src with nonces or hashes for any allowed inline blocks, and restrict external style origins. Also disallow loading images/fonts from untrusted origins if possible. [1][5]
- Avoid exposing sensitive values in attributes/DOM where CSS selectors can read them; prefer storing secrets server‑side and minimize sensitive data in the page.
- Audit/scan for style injection sinks (template engines, RPO-relative-path issues, CMS widgets) and patch input handling. See academic/industry analyses for attack patterns and RPO risk. [6][3]

- review a specific code snippet and point out the exact sink and fix; or
- prepare a minimal safe wrapper that accepts limited styling and escapes/whitelists it.

Sanitize CSS content before injecting into style element to prevent CSS injection attacks.
The code directly concatenates editor content into a <style> element's textContent property. While textContent prevents HTML injection, CSS injection remains possible—attackers can use CSS selectors and background-image/@import directives to exfiltrate sensitive data, perform clickjacking, or load malicious resources. WordPress's sanitize_textarea_field() only strips HTML tags and does not provide CSS-safe escaping.
Mitigations:
- Whitelist and validate CSS properties/values using a strict allowlist (e.g., reject selectors containing colons,
@,url(), orattr()) - Parse the CSS AST and reject dangerous constructs before rendering
- Implement a Content-Security-Policy that disallows
unsafe-inlinestyles and uses nonces for any approved inline<style>blocks - Sandbox user-supplied CSS in an iframe with a restrictive CSP

1094-1107: Optional: also clear editor value when resetting the custom CSS UI
resetCustomCSSEditor()safely unchecks the toggle and hides the editor wrapper, which is great. If the reset operation is also meant to wipe any per‑style custom CSS, consider additionally clearing the underlying textarea/input value (or invoking whatever logic normally syncs editor content) so that stale CSS doesn’t reappear when the toggle is turned back on after a reset.

</function_calls>Based on my comprehensive analysis of the CSS file, I can now provide the rewritten review comment:
✓ No duplicate CSS properties or conflicting background values detected in the minified output.
After parsing and analyzing all 700+ CSS selector blocks in the minified file, no instances of duplicate properties (including
text-align,border-radius, ormin-widthwithin the same selector) or conflictingbackground-color+backgroundcombinations were found. The minified CSS is structurally sound.If Biome previously flagged these issues on an earlier version, they appear to have been resolved in the current state of the file. If you have specific Biome error output to validate, please share it for cross-verification.

public static function get_custom_css( $single_style_settings = null ) { // If the single style settings are passed, return the custom CSS from the single style settings. - if ( ! empty( $single_style_settings['single_style_custom_css'] ) && ! empty( $single_style_settings['enable_style_custom_css'] ) ) { + if ( is_array( $single_style_settings ) && ! empty( $single_style_settings['single_style_custom_css'] ) && ! empty( $single_style_settings['enable_style_custom_css'] ) ) { return $single_style_settings['single_style_custom_css']; }

Based on my verification, I found that while the security concern about $id is technically valid, the actual risk is lower than the original review suggested. Here are my findings:
Vulnerability Status:
- The
$idparameter is indeed used unsanitized in JavaScript generation at lines 882-884 - However, the only call site in the codebase (_quick-settings.php:258) passes a hardcoded safe value:
'frm_single_style_custom_css' - The method is public but only callable from admin pages with
frm_change_settingscapability
Recommendation:
The code should add sanitization to $id for defense-in-depth, since the method is public and could be called by extensions with user-controlled data.
Sanitize the $id parameter before using it in JavaScript context.
The $id parameter extracted from $extra_args at line 810 is embedded directly into JavaScript at lines 882-884 without sanitization. While the current call site uses a hardcoded safe value, the public method signature allows external callers to pass arbitrary values. For defense-in-depth, use wp_kses_js_entities() or esc_attr() to sanitize $id before passing it to sprintf().
Static analysis warnings about unused variables ($message, $show_errors, $custom_css, $heading, $textarea_params) are false positives—these are used in the view included at line 821.
