- Severity: CVSS 3.1 (Low), CNA
- Vector: CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:L/A:N
- mitre rates this low
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 1.6.20, 1.7.5
- Published: 2026-10-22 · Updated: 2026-10-26

## Affected

- Roundcube Webmail: from 1.6.0, fixed in 1.6.20; from 1.7.0, fixed in 1.7.5

## 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.
