Summary
Jenkins pom2config Plugin 1.2 and earlier does not configure its XML parser to prevent XML external entity (XXE) attacks, allowing attackers with Overall/Read and Item/Read permissions to have Jenkins parse a crafted XML file that uses external entities for extraction of secrets from the Jenkins controller or server-side request forgery.
Exploit prediction
2.44% chance of exploitation in the next 30 days, higher than 84% of all scored CVEs (FIRST EPSS, 2026-11-08).
