GHSA-2x9c-vp3g-hvv2Jenkins EC2 Fleet Plugin has a cross-site request forgery (CSRF) vulnerability2026-06-24ghsa · osvUS
Jenkins EC2 Fleet Plugin 4.2.3.539.v8fedff2a_81c3 and earlier does not perform permission checks in several HTTP endpoints used to validate cloud configurations. This allows attackers with Overall/Read permission to connect to an attacker-specified URL using attacker-specified credentials IDs obtained through another method, capturing AWS credentials stored in Jenkins. Additionally, these HTTP endpoints do not require POST requests, resulting in a cross-site request forgery (CSRF) vulnerability. EC2 Fleet Plugin 4.2.3.540.va_6eedb_7b_c112 requires Overall/Administer permission and POST requests to perform these form validation actions.
