Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Eclipse Jetty jetty-util 12.0.0 to before 12.0.35 and 12.1.0 to before 12.1.9 fails to normalize dot-dot path segments that follow a semicolon path parameter. A remote, unauthenticated attacker can send a crafted path to bypass path-based security constraints. Upgrade to 12.0.35 or 12.1.9.
