CVE-2026-22723: UAA User Token Revocation logic error
Inappropriate user token revocation due to a logic error in the token revocation endpoint implementation in Cloudfoundry UAA v77.30.0 to v78.7.0 and in Cloudfoundry Deployment v48.7.0 to v54.10.0.
Security readout for executives and security teams
Plain-English summary
CVE-2026-22723 is a Cloud Foundry UAA logic flaw that can cause inappropriate user token revocation. The main business risk is availability: users or services may lose valid access tokens unexpectedly, disrupting authentication-dependent operations. The provided sources do not show active exploitation.
Executive priority
Treat this as a moderate-priority availability risk for Cloud Foundry environments. It is not currently cited as actively exploited, but affected authentication infrastructure can create service disruption if tokens are revoked incorrectly.
Technical view
The issue affects Cloud Foundry UAA v77.30.0 through v78.7.0 and Cloud Foundry Deployment v48.7.0 through v54.10.0. CVSS 3.1 is 6.5, with network access, low complexity, low privileges, no user interaction, and high availability impact. Listed CWEs are CWE-640 and CWE-693.
Likely exposure
Exposure is likely limited to environments running the named Cloud Foundry UAA or Cloud Foundry Deployment version ranges. Organizations should verify exact deployed versions and whether UAA token revocation functionality is reachable by authenticated users.
Exploitation context
The source bundle marks KEV as false and provides no cited evidence of active exploitation or public weaponization. Risk is still operationally relevant because the CVSS vector indicates authenticated network access could affect availability without user interaction.
Researcher notes
Evidence is limited to the CVE metadata and Cloud Foundry advisory reference. The bundle does not name a fixed version or detailed mitigation. Avoid assuming confidentiality or integrity impact because the CVSS vector lists C:N and I:N.
Mitigation direction
Check Cloud Foundry advisory for fixed versions and upgrade guidance.
Inventory UAA and Cloud Foundry Deployment versions across all foundations.
Prioritize upgrades for internet-facing or broadly accessible UAA deployments.
Review monitoring for unexpected token revocation spikes or authentication disruption.
Restrict administrative and token-management access to least privilege where applicable.
Validation and detection
Confirm whether UAA versions fall within v77.30.0 through v78.7.0.
Confirm whether Cloud Foundry Deployment versions fall within v48.7.0 through v54.10.0.
Review UAA logs for unusual token revocation activity.
Validate that vendor-recommended patched versions are deployed after remediation.
Check authentication-dependent services for recent unexplained availability incidents.

These fields come from the CVE record and ADP containers, not from Glexia's Take. They preserve time-varying source decisions such as CISA SSVC, KEV status, CVSS metrics, and provider references.
We collect every scored CVSS vector available in the official CNA and ADP containers. When more than one version is present, the table keeps the source vectors side by side instead of collapsing them into the highest score.
