Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Contao contao/core-bundle and contao/contao, versions >=5.7.0 and <5.7.7, are affected by a path traversal flaw in the job attachment download endpoint. An authenticated backend user with access to one job can supply an attachment identifier containing "../" segments to read files from another job's directory, though the job UUIDs are random v4 values, which limits practical exploitation to cases where the target UUID is already known or obtained. Upgrade to 5.7.7.
