Summary

OpenClaw is an npm-distributed application. In versions >= 2026.4.25 and < 2026.8.1, the workspace environment-variable filter did not block variables ending in `_ENDPOINT`, so an untrusted workspace `.env` file could set AZURE_SPEECH_ENDPOINT. Azure Speech preferred that value over the configured region, so when a synthesis or voice-list request was made, the attacker-selected endpoint received the operator's Azure Speech key in the request header, allowing the key to be reused against the operator's Azure Speech resource. Exploitation requires an operator to start OpenClaw in attacker-controlled workspace content with Azure Speech configured with a key and region and no trusted endpoint override set. The issue is fixed in 2026.8.1.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
