CVE-2026-11481: Use of Weak Hash in yoanbernabeu grepai
CVE-2026-11481 is a low-severity vulnerability in the yoanbernabeu grepai software up to version 0. 35. 0. It involves the use of a weak hash function in the PostgresStore. LookupByContentHash function within the Postgres Embedding Cache component. Exploitation requires local access, a high level of complexity, and is difficult to execute. The vulnerability has been publicly disclosed, but no official fix has yet been accepted. No known exploits are currently in the wild.
AI Analysis
Technical Summary
This vulnerability affects the function PostgresStore.LookupByContentHash in the file indexer/chunker.go of the grepai product by yoanbernabeu. Manipulating the content_hash argument can cause the use of a weak hash algorithm, potentially undermining the integrity or security of the embedding cache. Exploitation requires local access with limited privileges and is considered difficult due to the complexity involved. Although a pull request to fix the issue exists, it has not been merged or officially released as a patch.
Potential Impact
The impact is limited due to the low severity score (CVSS 2.0) and the requirement for local access and high attack complexity. The use of a weak hash may reduce the robustness of data integrity checks within the embedding cache, but no direct privilege escalation, denial of service, or data exposure is indicated. There are no known exploits in the wild at this time.
Mitigation Recommendations
No official fix or patch is currently available. A pull request addressing the issue awaits acceptance. Until an official patch is released, users should restrict local access to trusted users only to reduce risk. Monitor the vendor's repository or advisory channels for updates regarding the acceptance of the fix.
