Tiki 24.15 is a security maintenance release that also includes selected bug fixes and enhancements since Tiki 24.14.

Users of Tiki 24.14 are strongly encouraged to upgrade.

• [+] Installer base images must be local
  • Loading installer base images from remote URLs is no longer supported for security reasons. Administrators using custom base images should place the SQL file in the appropriate local db/ directory and reference it locally.

• [+] Verify custom PHP CLI configuration
  • PHP CLI paths are now validated before execution. Administrators using a custom or non-standard PHP CLI path should ensure that it points to a valid PHP executable.

    
    

• [+] Language: block path traversal and PHP injection in translation editor
  • Prevent path traversal and PHP injection vulnerabilities in the translation editor when handling custom language files.
