CVE-2025-32754: Jenkins SSH-Agent

Critical severity, CVSS 9.1. EPSS: 0.5% chance of exploitation in the next 30 days.

In jenkins/ssh-agent Docker images 6.11.1 and earlier, SSH host keys are generated on image creation for images based on Debian, causing all containers based on images of the same version use the same SSH host keys, allowing attackers able to insert themselves into the network path between the SSH client (typically the Jenkins controller) and SSH build agent to impersonate the latter.

Affected products

• Jenkins SSH-Agent: before 6.11.2 (fixed in 6.11.2)
