Detailsinfo

A vulnerability, which was classified as problematic, has been found in OpenClaw up to 2026.8.0. Affected by this issue is an unknown function of the component Workspace Environment-Variable Filter. The manipulation of the argument AZURE_SPEECH_ENDPOINT with an unknown input leads to a input validation vulnerability. Using CWE to declare the problem leads to CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. Impacted is confidentiality. CVE summarizes:

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.

The advisory is shared for download at github.com. This vulnerability is handled as CVE-2026-100569 since 09/26/2026. The exploitation is known to be easy. The attack needs to be approached locally. Successful exploitation requires user interaction by the victim. There are known technical details, but no exploit is available.

Upgrading to version 2026.8.1 eliminates this vulnerability.
