Description
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.
