Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-266: Incorrect Privilege Assignment, where a product incorrectly assigns a privilege to a particular actor, creating an unintended sphere of control for that actor. In Deepsearcher, 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 weakness has been identified in zilliztech deep-searcher up to 0.0.2. This affects the function CollectionRouter.invoke of the file deepsearcher/agent/collection_router.py. This manipulation of the argument kwargs causes improper access controls. Remote exploitation of the attack is possible. The exploit has been made available to the public and could be used for attacks. The pull request to fix this issue awaits acceptance.
