Vulnerability in Roundcube Webmail
CVSS 3.1
EPSS <1%1 agency advisoryNo fix listed yet
[ Description ]Official description
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.
