CVE-2025-32755 is a critical vulnerability affecting Jenkins SSH-slave Docker images based on Debian. It stems from SSH host keys being generated during image creation, leading to all containers of the same image version sharing identical keys. This allows a man-in-the-middle attacker to impersonate SSH build agents, potentially compromising the Jenkins controller. With a CVSS score of 9.1 (CRITICAL), this network-exploitable vulnerability requires no user interaction and could lead to high confidentiality and integrity impacts. Currently, there is no evidence of active exploitation, public exploit code, or significant community discussion.
