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:
