Published: 29 March 2022
Summary
CVE-2022-28140 is a high-severity Improper Restriction of XML External Entity Reference (CWE-611) vulnerability in Jenkins Flaky Test Handler. Its CVSS base score is 8.1 (High).
Operationally, ranked at the 37.2th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
Deeper analysis
Jenkins Flaky Test Handler Plugin 1.2.1 and earlier is affected by an XML external entity vulnerability because the plugin does not configure its XML parser to prevent XXE attacks, corresponding to CWE-611. The issue carries a CVSS 3.1 base score of 8.1 reflecting network attack vector, low attack complexity, and low privileges required.
An authenticated user with network access can supply a crafted XML document that the plugin processes, enabling the attacker to read arbitrary files from the Jenkins controller or perform server-side request forgery, resulting in high impact to confidentiality and integrity.
The Jenkins security advisory published on 2022-03-29 and the corresponding oss-security mailing list posting describe the flaw under SECURITY-1896 and direct administrators to updated plugin releases that properly disable external entity resolution. The associated EPSS score rose materially from a low baseline to a peak of 0.0917 on 2025-12-11 before receding, indicating a period of increased exploitation interest after public disclosure.
