Summary
grepai Uses a Broken or Risky Cryptographic Algorithm
Details

A vulnerability was determined in yoanbernabeu grepai up to 0.35.0. The affected element is the function PostgresStore.LookupByContentHash of the file indexer/chunker.go of the component Postgres Embedding Cache. Executing a manipulation of the argument content_hash can lead to use of weak hash. The attack needs to be launched locally. The attack requires a high level of complexity. The exploitability is described as difficult. The exploit has been publicly disclosed and may be utilized. The pull request to fix this issue awaits acceptance.
