Package : roundcube
CVE ID : CVE-2026-25916 CVE-2026-26079
Debian Bug : 1127447
CERT Polska and nullcathedral discovered that roundcube, a skinnable
AJAX based webmail solution for IMAP servers, did not correctly
process and sanitize requests. This would allow an attacker to perform
CSS injection attacks, or leak sensitive information.
For the oldstable distribution (bookworm), these problems have been fixed
in version 1.6.5+dfsg-1+deb12u7.
For the stable distribution (trixie), these problems have been fixed in
version 1.6.13+dfsg-0+deb13u1.
We recommend that you upgrade your roundcube packages.
For the detailed security status of roundcube please refer to
its security tracker page at:
