Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-327: Use of a Broken or Risky Cryptographic Algorithm, where the product uses a broken or risky cryptographic algorithm or protocol. In Github.com/yoanbernabeu/grepai, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

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.
