Summary
PinchTab, a standalone HTTP server giving AI agents control of a Chrome browser, versions 0.8.2 and below, has a blind SSRF flaw in its /download endpoint. validateDownloadURL() checks only the initial user-supplied URL, so the embedded Chromium browser can follow attacker-controlled redirects or navigations to internal network addresses after validation. Exploitation requires security.allowDownload=true, which is disabled by default.
Mitigation
Fixed in 0.8.3.
