5.2.0

Security

• Critical: unauthenticated admin bypass. Route and role checks matched on the raw request URI with a substring contains() instead of the container-normalized servlet path. A crafted URI like /x;/manage/viewUsers.ktrl could reach any /manage/* or /admin/* controller — including full account creation — with zero authentication. Now matched on getServletPath() with an exact match.
• SSH terminal WebSocket had no real auth gate. The /admin/terms.ws upgrade request bypasses the servlet-container AuthFilter entirely; it was only "failing safe" by accident, via an uncaught NPE. SecureShellWS.onOpen now explicitly validates a live admin auth token before allowing the connection.
• Added login throttling. Brute-force login attempts were previously unbounded. Now rate-limited per client IP (configurable via maxLoginAttemptsPerIP / loginThrottleWindowMinutes, default 10 attempts / 5 minutes) rather than per-account, so an attacker can't lock out a known admin by deliberately failing their password.
• Fixed a file upload path traversal. UploadAndPushKtrl.push() didn't sanitize the uploaded filename before using it to build SFTP push/cleanup paths, allowing a crafted ../../../etc/passwd-style value to read or delete arbitrary local files.
• Hardened DB connection handling. All 12 DAO classes moved to try-with-resources, closing two real connection leaks: one in the terminal output-polling loop (a leak every 25ms on exception) and one on every failed external-auth attempt.

Added

• SAML 2.0 SSO, alongside the existing LDAP/JAAS auth — works with Entra ID, Okta, ADFS, or any SAML 2.0 IdP.
  • Self-signed SP signing/encryption keys generated automatically (no config needed); every outgoing AuthnRequest is signed.
  • New /saml/metadata endpoint for IdP-side setup via URL import.
  • Optional encrypted-assertion support (samlWantEncryptedAssertions).
  • Config is entirely env-var/file driven — no new admin UI, matching the LDAP pattern.
  • SAML role/group claims map onto Bastillion profiles the same way LDAP groups already do.

Changed

• Modernized UI throughout: new logo/branding (SVG), responsive navbar, consistent button styling across admin and manage views.
• Terminal polish: fixed resizing, cursor/clipboard input, selection clearing after copy, and a duplicate-session output race.
• Fixed zsh sessions leaking PROMPT_EOL_MARK markers into terminal/audit output.
• Raised the free system limit.
• Refreshed all product screenshots.
• Upgraded embedded Jetty from 11 (Jakarta EE 9) to 12 (Jakarta EE 10).

• github/codeql-action 4 → 4.37.7

Upgrade note: if you run behind LDAP/JAAS today, this release is a drop-in upgrade — no config changes required. SAML is opt-in via new env vars. Given the auth-bypass and WS-terminal-auth fixes above, upgrading promptly is strongly recommended for all deployments.
