Answer in brief
CVE-2026-13493 records a Low severity (CVSS 3.1) vulnerability in AIDC-AI ComfyUI-Copilot Workflow Checkpoint Restore conversation_api.py resource injection. The current sources do not mark it as known exploited. The current feed maps AIDC-AI/ComfyUI-Copilot (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 3.1. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

A flaw has been found in AIDC-AI ComfyUI-Copilot up to 2.0.28. This issue affects some unknown processing of the file backend/controller/conversation_api.py of the component Workflow Checkpoint Restore Handler. Executing a manipulation can lead to improper control of resource identifiers. The attack may be performed from remote. A high complexity level is associated with this attack. The exploitability is assessed as difficult. The exploit has been published and may be used. The pull request to fix this issue awaits acceptance.
