Security readout for executives and security teams
Plain-English summary
CVE-2026-5795 is a Jetty authentication flaw that can let one request inherit authentication state left behind by another request on the same server thread. In affected deployments, this can break access control and allow privilege escalation. The supplied sources rate it high severity, but do not show active exploitation.
Executive priority
Treat as a high-priority remediation item for internet-facing or sensitive Jetty applications using JASPI authentication. It threatens confidentiality and integrity through possible privilege escalation, but current supplied evidence does not support emergency active-exploitation handling.
Technical view
Jetty JASPIAuthenticator can return early after setting two ThreadLocal variables without clearing them. If a later request reuses that thread, stale authentication context can be inherited, causing broken access control. The CVSS 3.1 score is 7.4 with high confidentiality and integrity impact and high attack complexity.
Likely exposure
Exposure is most likely in applications running Eclipse Jetty versions or branches listed as affected and using JASPI/JASPIAuthenticator-based authentication. Products embedding Jetty may also require review. The source bundle does not provide complete fixed-version mapping.
Exploitation context
The source bundle marks KEV as false and provides no cited evidence of active exploitation. Network reachability and no required privileges increase concern, but CVSS marks attack complexity high, suggesting exploitation depends on specific request timing, thread reuse, or application conditions.
Researcher notes
Key uncertainty is exact affected and fixed patch-level versions; the bundle lists major/minor baselines and external advisories, but not detailed version ranges. Focus validation on JASPIAuthenticator usage, ThreadLocal cleanup behavior, and whether downstream vendors backported fixes.
Mitigation direction
- Review Eclipse Jetty advisory GHSA-r7p8-xq5m-436c for fixed-version guidance.
- Apply applicable Red Hat RHSA updates for Red Hat-packaged Jetty components.
- Inventory applications embedding Jetty, not only standalone Jetty servers.
- Prioritize systems using JASPI or JASPIAuthenticator authentication paths.
- If fixed versions are unclear, follow vendor guidance before changing authentication design.
Validation and detection
- Identify Jetty versions 9.4.0, 10.0.0, 11.0.0, 12.0.0, and 12.1.0 in use.
- Check whether deployed applications enable JASPI or JASPIAuthenticator.
- Review dependency trees for embedded Jetty packages in Java applications.
- Confirm vendor advisory applicability for Red Hat-distributed components.
- After updates, verify the running Jetty package version against vendor guidance.
