Package : roundcube Version : 1.4.15+dfsg.1-1+deb11u5 CVE ID : CVE-2025-49113 Debian Bug : 1107073

Kirill Firsov discovered that Roundcube, a skinnable AJAX based webmail solution for IMAP servers, was performing PHP Object deserialization on unvalidated input, which could lead to remote code execution by an authenticated attacker.
