Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
The org.opendaylight.mdsal:mdsal-artifacts package is affected in versions up to and including 13.0.1, and no fixed version is listed. A controller that holds the follower role in an OpenDaylight clustering deployment can configure flow entries, which the role should not allow. The source gives few details about the attack conditions. No fix is listed, so there is no upgrade to apply.
