Title

cc-connect through 1.5.0 User Allowlist Bypass via Feishu Card Actions

Summary

cc-connect through 1.5.0 fails to enforce per-user allowlist filtering in the onCardAction handler for Feishu interactive card callbacks. Attackers can dispatch agent commands by triggering card actions in admitted chats, bypassing the per-user access controls that protect the text message handler.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
