Tiki 27.8 is a security maintenance release that also includes selected bug fixes and enhancements since Tiki 27.7.

Users of Tiki 27.7 are strongly encouraged to upgrade.

  • 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.

  • 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.

• [+] Graph formula: replace eval() with Math_Formula library
  • Replace unsafe eval() usage in graph formulas with the Math_Formula library and a whitelist of supported mathematical functions for safer formula evaluation.
