CWE-20Published: October 6, 2025· Updated: Jun 17, 2026

9.8

CVSS v3.1

Official Description

A vulnerability has been found in ILIAS up to 8.23/9.13/10.1. This affects the function unserialize of the component Base64 Decoding Handler. Such manipulation of the argument f_settings leads to deserialization. It is possible to launch the attack remotely. Upgrading to version 8.24, 9.14 and 10.2 is able to mitigate this issue. It is advisable to upgrade the affected component.

Risk Analysis

This critical deserialization vulnerability in ILIAS up to versions 8.23, 9.13, and 10.1 allows a remote attacker to manipulate the 'f_settings' argument in the Base64 Decoding Handler. With a CVSS score of 9.8, this flaw could lead to arbitrary code execution or other severe impacts. The lack of an EPSS score means the likelihood of exploitation is not yet quantified, but the critical severity warrants immediate attention.

No public exploit is currently known for this vulnerability. It is remotely exploitable due to the network attack vector and low attack complexity.

Recommended Action

Upgrade ILIAS to version 8.24, 9.14, or 10.2 to mitigate this deserialization vulnerability. Ensure all input is properly validated and sanitized before deserialization.
