Session theft via retained externally authenticated session
Published Feb 4, 2026 · Updated Feb 4, 2026
Session fixation in GLPI 0.71 through 10.0.22 and 11.0.0-alpha through 11.0.4 allows physically proximate attackers to steal another user's session. GLPI retains an existing session when SSO variables change the externally authenticated identity; the maintainer has not disclosed the responsible function. Exploitation requires remote authentication and access to the same machine as a previously authenticated user, and the disclosed consequence is unauthorized access to that user's GLPI session.
