GHSA-8F65-RC5R-W7C8

Vulnerability from github – Published: 2026-10-22 03:33 – Updated: 2026-10-22 03:33

Details

Roundcube Webmail before 1.6.20 and 1.7.x before 1.7.5 allows the disabled_actions configuration setting to be bypassed. The check compared only the action name as requested, so a remote authenticated attacker could reach an action listed in disabled_actions by requesting it through its deprecated alias instead. Upstream fixed this in the commit “Fix bug where deprecated action aliases bypassed disabled_actions setting”, which moves the check into rcmail::action_handler() and resolves aliases before comparing.

Severity

3.1 (Low)
