Machine-written summary

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

The grepai Go module github.com/yoanbernabeu/grepai, versions up to and including 0.35.0, has a weak hash issue in the PostgresStore.LookupByContentHash function, which is used by its Postgres embedding cache. An attacker with local access could exploit this with considerable effort, and the source says exploitation is difficult and a public exploit exists. No fixed version is listed.
