Who should care

Operators, administrators, and security teams running Cloud Foundry UAA or cf-deployment should pay attention, especially where token-based authentication is used in production or where unexpected revocation would interrupt user access.

Technical summary

The supplied description identifies a logic error in the token revocation endpoint implementation that can revoke user tokens inappropriately. NVD classifies the issue as network-accessible, low-complexity, low-privilege, and requiring no user interaction, with no confidentiality or integrity impact and high availability impact (CVSS v3.1: AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H).

Defensive priority

Medium. Prioritize remediation in environments that depend on Cloud Foundry authentication continuity, because incorrect token revocation can disrupt logins, sessions, and automation.

Recommended defensive actions

  • Inventory Cloud Foundry UAA and cf-deployment deployments and compare them against the affected version ranges in the CVE record and NVD metadata.
  • Upgrade or otherwise move to a non-vulnerable Cloud Foundry release identified by the vendor advisory.
  • Review token revocation and authentication logs for unexpected revocations, repeated sign-ins, or correlated access failures.
  • Validate any administrative or automated workflows that invoke the token revocation endpoint.
  • Alert support or operations teams to user reports of involuntary sign-out or authorization failures while remediation is underway.

Evidence notes

This debrief is based on the CVE record published on 2026-03-05 and modified on 2026-05-10, plus the NVD entry and referenced Cloud Foundry advisory. The source corpus states the issue is an inappropriate user token revocation caused by a logic error in the token revocation endpoint. NVD lists the advisory reference and affected CPE ranges. One data-quality note: the human-readable description says cf-deployment v48.7.0 to v54.10.0, while the NVD CPE metadata marks cf-deployment vulnerable through 54.11.0; that mismatch is preserved here rather than resolved.
