CVE-2022-45397Network attack vector

Secret extraction and SSRF via external entities

Published Nov 15, 2022 · Updated Apr 30, 2025

XXE in Jenkins OSF Builder Suite :: XML Linter Plugin 1.0.2 and earlier allows attackers to extract agent secrets or cause SSRF via crafted XML. The build step passes attacker-controlled XML to a parser without disabling external entity resolution, so entity URIs can read local resources or initiate network requests. Exploitation requires control of XML input while lacking the broader ability to alter build steps, Jenkinsfiles, test code, or other agent-executed content.
