Open WebUI: revocation must cross HTTP and realtime boundaries

CVE-2026-59219 documents inconsistent session invalidation: HTTP authentication consulted revocation state, while realtime authentication checked only token signature and expiry. The reported local comparison shows revoked credentials rejected by HTTP but accepted for new realtime authentication. Cryptographic validity had been mistaken for continuing session authority.

How to use this reference

Editorial lesson: model revocation as a shared invariant across every transport. The advisory identifies 0.10.0 as patched through shared revocation checks. Distinguish denial of new connections from termination of existing ones when reviewing remediation guarantees.

Before reading

  • JWT validity, session revocation and asynchronous transports

Context and limits

  • Applies to Redis-backed versions 0.9.0 through versions before 0.10.0 and requires possession of an otherwise valid revoked token. Without Redis, per-token invalidation is unsupported by design.
  • Realtime disclosure and impersonation are maintainer-described consequences; broader production exploitation is not established. Terminal access additionally depends on terminal configuration; HTTP remains protected.
  • Existing-connection termination is not established. The advisory identifies doge-woof as the publishing account and credits huslayer826 as Reporter and Classic298 as Coordinator. The reviewed advisory provides no explicit article byline; these publication and credit roles do not establish article authorship. Separate from the catalog's role-claim provenance advisory.
