FKIE_CVE-2026-114719

Vulnerability from fkie_nvd - Published: 2026-10-22 02:16 - Updated: 2026-10-22 16:45
Severity
3.7 (Low) - CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N
Summary
Roundcube Webmail before 1.6.20 and 1.7.x before 1.7.5 is affected by a CSRF validation bypass in the mark-as-junk action of the markasjunk plugin. The plugin read the _uid parameter from POST data but passed it to rcmail::get_uids() without constraining the input mode, so values re-read inside that helper could be taken from the query string and the action carried out without a valid CSRF token. Upstream fixed this in the commit “Fix CSRF validation bypass in the mark-as-junk action”, which passes rcube_utils::INPUT_POST explicitly.
