Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
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.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

A resource consumption vulnerability exists in the recall_relevant_memories_to_working_memory function within core/cat/looking_glass/stray_cat.py of the Cheshire Cat Core AI agent memory system. The function, responsible for retrieving relevant memories into working memory, allows uncontrolled resource usage that can be exploited remotely. The exploit is publicly available.

MitigationImplement resource limits on memory recall operations (e.g., maximum memories to retrieve, timeouts, pagination). Add input validation on query parameters to prevent malicious memory retrieval patterns. Consider rate limiting on the recall function until vendor patch is available.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed Cheshire Cat Core version
    Check the package version via pip show cheshire-cat-core or look for version file in the installation directory, or check the version attribute if accessible via API
    Affected if Version is unknown, unpatched, or falls within the vulnerable range (any version prior to vendor fix)
  2. Verify vulnerable file exists
    Locate core/cat/looking_glass/stray_cat.py in the installation directory and confirm the recall_relevant_memories_to_working_memory function is present
    Affected if The file and function exist in the installed version (vulnerability is present in code)
  3. Confirm memory recall function is exposed
    Check API endpoints or any web-accessible routes that invoke recall_relevant_memories_to_working_memory; review application routing configuration or OpenAPI spec if available
    Affected if The recall function is exposed via HTTP/API and reachable from network (enables remote exploitation)
  4. Check for existing resource limits
    Inspect configuration files, function code, or environment variables for limits on memory retrieval such as max_results, timeout, or pagination settings
    Affected if No resource limits are configured and the function is exposed (vulnerability is exploitable without constraints)

Affected if Cheshire Cat Core with the vulnerable function is installed, the recall_relevant_memories_to_working_memory function is exposed via API, and no resource limits are in place to constrain memory retrieval operations.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

From vendor data
Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Implement resource limits on memory recall operations (e.g., maximum memories to retrieve, timeouts, pagination). Add input validation on query parameters to prevent malicious memory retrieval patterns. Consider rate limiting on the recall function until vendor patch is available.
