SCA: security update for github.com/pinchtab/pinchtab (GHSA-qwxp-6qf9-wr4m)
low Tenable Cloud Security Plugin ID 438940
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- PinchTab is a standalone HTTP server that gives AI agents direct control over a Chrome browser. Versions
0.8.2 and below have a Blind SSRF vulnerability in the /download endpoint. The validateDownloadURL()
function only checks the initial user-supplied URL, but the embedded Chromium browser can follow attacker-
controlled redirects/navigations to internal network addresses after validation. Exploitation requires
security.allowDownload=true (disabled by default), limiting real-world impact. An attacker-controlled page
can use JavaScript redirects or resource requests to make the browser reach internal services from the
PinchTab host, resulting in a blind Server-Side Request Forgery (SSRF) condition against internal-only
services. The issue has been patched in version 0.8.3. (CVE-2026-33081)
Solution
Update the github.com/pinchtab/pinchtab library and its related packages to version 0.8.3 or later.See Also
