CVE-2026-25101 PUBLISHED

Session Fixation in Bludit

Assigner: CERT-PL
Reserved: 29.01.2026 Published: 27.03.2026 Updated: 27.03.2026

Bludit allows user's session identifier to be set before authentication. The value of this session ID stays the same after authentication. This behavior enables an attacker to fix a session ID for a victim and later hijack the authenticated session.

This issue was fixed in version 3.17.2.
