This could lead to unauthorized information disclosure. The issue is resolved in version 26.0.0.
Potential Impact
Unauthenticated attackers can access git repositories and their history through the gitlist plugin, potentially exposing sensitive source code or repository metadata. There is no indication of privilege escalation or code execution. The CVSS 4.0 base score is 6.9 (medium severity), reflecting network attack vector, low complexity, no privileges or user interaction required, and low impact on confidentiality.
Mitigation Recommendations
Upgrade haxcms-php to version 26.0.0 or later, which patches this authorization bypass vulnerability. No other official remediation or temporary fixes are documented. Until upgraded, restrict access to the gitlist plugin or disable it if possible.
