Jenkins 2.217 through 2.441 (both inclusive), LTS 2.222.1 through 2.426.2 (both inclusive) does not perform origin validation of requests made through the CLI WebSocket endpoint, resulting in a cross-site WebSocket hijacking (CSWSH) vulnerability, allowing attackers to execute CLI commands on the Jenkins controller.

We don't hand-write analysis for the hundreds of thousands of vulnerabilities in the database; that wouldn't be honest. For notable, high-impact vulnerabilities our team writes the mechanism, detection and remediation steps.

Affected versions
NVD version ranges (for catalog products). Add the product to your stack with a version and matching uses these.

Versions reported by the vendor
Affected version ranges reported by the assigning authority (jenkins). Independent of NVD's CPE analysis and usually ahead of it.
