From 211105543491c46eb63d2422c55226fdd2f1ce12 Mon Sep 17 00:00:00 2001 From: Security Fix PR Date: Sat, 11 Oct 2025 05:38:05 +0000 Subject: [PATCH 1/5] Fix unsafe quoting vulnerability in network hook generation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit **Alert Number**: #9 **Severity**: Critical (security_severity_level: critical) **Rule**: go/unsafe-quoting **CWE**: CWE-78, CWE-89, CWE-94 ## Vulnerability Description The code was embedding JSON data directly into a Python script template without proper quote escaping. If the JSON contained double quotes, it could break out of the string context and potentially allow code injection when the generated Python script is executed. ## Fix Applied 1. Added `strconv` import to use Go's built-in string quoting function 2. Used `strconv.Quote()` to properly escape the JSON string for safe embedding in Python code 3. Changed the Python template to use `json.loads()` with the properly quoted string instead of direct literal embedding 4. Added clear security comments explaining the fix ## Security Best Practices - Always use proper escaping when embedding dynamic data in code templates - Use `strconv.Quote()` for Go string literals that will be embedded - Validate and sanitize all user-provided data before code generation - Use structured APIs (like json.loads) rather than direct string embedding ## Testing Considerations - Test with domain lists containing special characters (quotes, backslashes) - Verify the generated Python script parses correctly - Ensure network permissions hook functions as expected - Validate no breaking changes to existing functionality 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- pkg/workflow/engine_network_hooks.go | 19 ++++++++++++++----- 1 file changed, 14 insertions(+), 5 deletions(-) diff --git a/pkg/workflow/engine_network_hooks.go b/pkg/workflow/engine_network_hooks.go index dcbe29c89e..3a1241cd1d 100644 --- a/pkg/workflow/engine_network_hooks.go +++ b/pkg/workflow/engine_network_hooks.go @@ -3,6 +3,7 @@ package workflow import ( "encoding/json" "fmt" + "strconv" "strings" ) @@ -13,13 +14,20 @@ type NetworkHookGenerator struct{} func (g *NetworkHookGenerator) GenerateNetworkHookScript(allowedDomains []string) string { // Convert domain list to JSON for embedding in Python // Ensure empty slice becomes [] not null in JSON - var domainsJSON []byte + var domainsJSON string if allowedDomains == nil { - domainsJSON = []byte("[]") + domainsJSON = "[]" } else { - domainsJSON, _ = json.Marshal(allowedDomains) + jsonBytes, _ := json.Marshal(allowedDomains) + domainsJSON = string(jsonBytes) } + // Use strconv.Quote to safely escape the JSON string for Python + // This prevents any quote-related injection vulnerabilities (CWE-78, CWE-89, CWE-94) + quotedJSON := strconv.Quote(domainsJSON) + + // Build the Python script using a safe template approach + // The JSON string is properly quoted and escaped, then parsed at runtime return fmt.Sprintf(`#!/usr/bin/env python3 """ Network permissions validator for Claude Code engine. @@ -32,7 +40,8 @@ import urllib.parse import re # Domain allow-list (populated during generation) -ALLOWED_DOMAINS = %s +# JSON string is safely escaped using Go's strconv.Quote +ALLOWED_DOMAINS = json.loads(%s) def extract_domain(url_or_query): """Extract domain from URL or search query.""" @@ -101,7 +110,7 @@ try: except Exception as e: print(f"Network validation error: {e}", file=sys.stderr) sys.exit(2) # Block on errors -`, string(domainsJSON)) +`, quotedJSON) } // GenerateNetworkHookWorkflowStep generates a GitHub Actions workflow step that creates the network permissions hook From e7a4b9a4d020286b4dc3c3c368301457467e929c Mon Sep 17 00:00:00 2001 From: Peli de Halleux Date: Fri, 10 Oct 2025 22:46:25 -0700 Subject: [PATCH 2/5] Potential fix for code scanning alert no. 15: Potentially unsafe quoting Co-authored-by: Copilot Autofix powered by AI <62310815+github-advanced-security[bot]@users.noreply.github.com> --- pkg/workflow/engine_network_hooks.go | 12 ++++++------ 1 file changed, 6 insertions(+), 6 deletions(-) diff --git a/pkg/workflow/engine_network_hooks.go b/pkg/workflow/engine_network_hooks.go index 3a1241cd1d..a8b0d9f5f9 100644 --- a/pkg/workflow/engine_network_hooks.go +++ b/pkg/workflow/engine_network_hooks.go @@ -3,7 +3,7 @@ package workflow import ( "encoding/json" "fmt" - "strconv" + // "strconv" removed; no longer needed "strings" ) @@ -22,12 +22,12 @@ func (g *NetworkHookGenerator) GenerateNetworkHookScript(allowedDomains []string domainsJSON = string(jsonBytes) } - // Use strconv.Quote to safely escape the JSON string for Python + // Embed domain list JSON directly as a Python literal (safe for []string from json.Marshal) // This prevents any quote-related injection vulnerabilities (CWE-78, CWE-89, CWE-94) - quotedJSON := strconv.Quote(domainsJSON) + // Use domainsJSON directly for ALLOWED_DOMAINS assignment // Build the Python script using a safe template approach - // The JSON string is properly quoted and escaped, then parsed at runtime + // The JSON array is embedded directly as a Python list literal return fmt.Sprintf(`#!/usr/bin/env python3 """ Network permissions validator for Claude Code engine. @@ -40,8 +40,8 @@ import urllib.parse import re # Domain allow-list (populated during generation) -# JSON string is safely escaped using Go's strconv.Quote -ALLOWED_DOMAINS = json.loads(%s) +# JSON array safely embedded as Python list literal +ALLOWED_DOMAINS = %s def extract_domain(url_or_query): """Extract domain from URL or search query."""
