CVE-2025-11346 is a critical deserialization vulnerability affecting ILIAS versions up to 8.23, 9.13, and 10.1. This flaw, located in the Base64 Decoding Handler's unserialize function, allows remote attackers to manipulate the f_settings argument, leading to arbitrary code execution. With a CVSS score of 9.8, it presents a severe risk due to its network-based attack vector, low attack complexity, and high impact on confidentiality, integrity, and availability. While no public exploit code (Metasploit, Nuclei, ExploitDB) or active exploitation has been observed, and community discussion is minimal, immediate upgrade to ILIAS versions 8.24, 9.14, or 10.2 is strongly recommended to mitigate this critical risk.
