Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
The PyPI package farm-haystack, versions 1.15.0 and earlier, contains hard-coded security-relevant constants, according to the source. The source gives few details about the exact constants or how they can be abused, and it does not describe what an attacker needs to reach them or what they could do. A patch exists as a commit in the deepset-ai/haystack repository, but no fixed package version is listed, so users should check that repository's history for the patch.
