Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-918: Server-Side Request Forgery (SSRF), where the web server receives a url or similar request from an upstream component and retrieves the contents of this url, but it does not sufficiently ensure that the request is being sent to the expected destination. In Openclaw, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Summary Gemini `web_search` citation redirect resolution used a private-network-allowing SSRF policy. A citation URL redirect could target loopback/private/internal destinations and be fetched by the gateway. ### Impact An attacker who can influence citation redirect targets could trigger internal-network requests from the OpenClaw host. ### Fix Citation redirect resolution now uses strict/default SSRF policy (no private-network override), blocking localhost/private/internal redirect targets. ### Affected and Patched Versions - Affected: `<= 2026.2.26` - Patched: `2026.3.1`
