CVE-2026-62220 (GCVE-0-2026-62220)

Vulnerability from cvelistv5 – Published: 2026-07-17 00:07 – Updated: 2026-07-17 10:37 X_Open Source

Title

OpenClaw 2026.2.25 < 2026.5.26 WebSocket Rate Limit Bypass

Summary

OpenClaw 2026.2.25 before 2026.5.26 allow a lower-trust caller or configured input path to bypass non-browser rate limits on WebSocket authentication attempts. When the affected feature is enabled and reachable by lower-trust input, this can consume gateway resources and reduce service availability.

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.
