Summary

Quake II server before R1Q2, as used in multiple products, allows remote attackers to corrupt the server's client state data structure by exiting a session without a valid disconnect command, then reconnecting, which prevents a mod from being notified of changes in the client state. NOTE: the impact of this issue will vary depending on which mod is being used.

Exploit prediction

1.39% chance of exploitation in the next 30 days, higher than 72% of all scored CVEs (FIRST EPSS, 2026-11-08).

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
