Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Graylog (org.graylog2:graylog2-server, Maven) versions 4.3.0 up to but not including 5.1.11, and 5.2.0-alpha.1 up to but not including 5.2.4, are affected. An attacker would need to inject their own session cookie into a victim's browser, possibly through XSS and a spoofed login screen, so that a reauthentication reuses that session and gains elevated access. Upgrade to 5.1.11 or 5.2.4. Until then, use short session expiration and log out unused sessions.
