GHSA-53VX-PMQW-863C

Vulnerability from github – Published: 2026-04-17 21:58 – Updated: 2026-05-08 01:32

Summary

OpenClaw: Browser SSRF policy default allowed private-network navigation

Details

Summary

Browser SSRF policy default allowed private-network navigation.

Affected Packages / Versions

Package: openclaw
Ecosystem: npm
Affected versions: < 2026.4.14
Patched versions: >= 2026.4.14

Impact

Browser SSRF protection could allow private-network navigation by default in paths where restrictive behavior was expected, exposing internal services or metadata endpoints through browser-driven requests.

Technical Details

The fix preserves strict SSRF configuration semantics, keeps private-network access disabled unless explicitly opted in, and updates loopback CDP readiness handling for the stricter default.

Fix

The issue was fixed in #66354 and #66386. The first stable tag containing the fix is v2026.4.14, and openclaw@2026.4.14 includes the fix.

7eecfa411df3d12e6b810e6ca5df47254fc3db3f
PR: #66354, #66386

Release Process Note

Users should upgrade to openclaw 2026.4.14 or newer. The latest npm release, 2026.4.14, already includes the fix.

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.
