Title

OpenPanel API Authentication Bypass via Unverified Client Secret

Summary

OpenPanel tracking API through commit bad75bddc74d12d36cfb843f4531d3b830a8d994 fails to verify client secret cryptographic hash before authorizing revenue events and bot filtering. Attackers with only a public client ID can supply arbitrary dummy secrets to inject forged revenue metrics and bypass bot detection filters.

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.
