Summary

browserless versions 1.44.0 through 2.56.7 fail to enforce file protocol restrictions in Playwright websocket endpoints, allowing authenticated token holders to read arbitrary files. Attackers can navigate Playwright-driven browsers to file scheme URLs and access files accessible to the container process despite the ALLOW_FILE_PROTOCOL setting defaulting to false.

Risk Assessment

Token holders can read arbitrary files in the container, potentially leading to exposure of sensitive data such as passwords, keys, or configurations.

Recommendation

Update browserless to a version newer than 2.56.7 that includes the fix. Additionally, restrict token access and monitor websocket usage.
