Summary

Duplicate Advisory: OpenClaw has Bypass in Webhook Rate Limiting via Pre-Authentication Secret Validation

Details

Duplicate Advisory

This advisory has been withdrawn because CVE-2026-34508 has been rejected as a duplicate of CVE-2026-34505. This link is maintained to preserve external references.

Original Description

OpenClaw before 2026.3.12 applies rate limiting only after webhook authentication succeeds, allowing attackers to bypass rate limits and brute-force webhook secrets without triggering 429 responses. Attackers can repeatedly guess invalid secrets to discover valid credentials and subsequently submit forged Zalo webhook traffic.

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.
