How to Fix CVE-2026-8319

To remediate this vulnerability, upgrade all affected Ai agents dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

ai-agents fixed: Latest secure release 
pip install ai-agents>=Latest secure release
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show ai-agents

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2026-8319, inspect your installed packages using pip:

pip show ai-agents

Analyze the terminal output to locate any version of Ai agents in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.

Note: The pip show ai-agents command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-400: Uncontrolled Resource Consumption, where the product does not properly control the allocation and maintenance of a limited resource. In Ai agents, 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 aiwaves-cn agents up to e8c4e3c2d19739d3dff59e577d1c97090cc15f59. Affected by this issue is the function recall_relevant_memories_to_working_memory of the file core/cat/looking_glass/stray_cat.py of the component cheshire_cat_core. This manipulation causes resource consumption. Remote exploitation of the attack is possible. The exploit has been made available to the public and could be used for attacks. This product follows a rolling release approach for continuous delivery, so version details for affected or updated releases are not provided. The project was informed of the problem early through an issue report but has not responded yet.
