Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Jenkins core and the cli package are vulnerable in versions from 2.529 up to but not including 2.541, and in versions before 2.528.3. An unauthenticated attacker who can reach the HTTP-based CLI can cause a denial of service because connections are not properly closed when the connection stream becomes corrupted. Upgrade jenkins-core and cli to 2.541 or 2.528.3. The source gives no workaround.
