Who should care

Jenkins administrators, platform owners, DevOps teams, and security teams responsible for internet-facing or broadly accessible Jenkins instances.

Technical summary

The available records identify an information disclosure issue in the Jenkins UI. Beyond that, the supplied source set is limited: it does not include vulnerability mechanics, affected versions, or a CVSS score. What is clear from CISA KEV is that the issue is considered actively exploited or historically exploited enough to require timely patching.

Defensive priority

High for any organization running Jenkins, especially if the UI is reachable by many users or exposed beyond internal networks. CISA added the CVE to KEV on 2023-05-12 with a remediation due date of 2023-06-02, so it should be treated as urgent.

Recommended defensive actions

  • Identify all Jenkins instances, including test and legacy systems.
  • Check vendor guidance in the Jenkins security advisory referenced by CISA.
  • Apply the vendor-recommended update or mitigation as soon as practical.
  • Restrict access to Jenkins UI to trusted networks and authenticated users only.
  • Review logs and access patterns for unusual UI requests or data exposure.
  • Track remediation status in vulnerability management workflows because this CVE is in CISA KEV.

Evidence notes

Source corpus evidence is limited to the CISA KEV record and its notes, which reference the Jenkins advisory URL and the NVD record. The corpus confirms the KEV dates (added 2023-05-12, due 2023-06-02) and the vulnerability class (information disclosure), but does not provide affected versions, CVSS, or exploit details.

Official resources

Publicly disclosed and listed by CISA as a Known Exploited Vulnerability; the supplied corpus does not include exploit details.
