Machine-written summary

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

Packages affected: kas before 5.3, fixed in 5.3. An attacker who has taken over a git repository used in a kas configuration can add a branch named like a commit ID. Because kas checks out by commit ID alone, a user may end up on that branch instead of the validated commit, with the SHA-256 case being the main concern. Upgrade to kas 5.3. Where possible, use signed commits or tags, or mirror the repository and verify it before use.
