CVE-2026-22723Network attack vector

Authenticated service interruption via improper token revocation

Published Mar 5, 2026 · Updated Mar 5, 2026

Protection mechanism failure in Cloud Foundry UAA 77.30.0 through 78.7.0 allows remote authenticated users to interrupt user access. The token revocation endpoint contains a logic error that revokes user tokens inappropriately, but Cloud Foundry has not disclosed the erroneous condition or code operation. Exploitation requires authenticated network access and can invalidate tokens, denying affected users continued access without disclosing or modifying their data.
