### Impact If PDF.js is used to load a malicious PDF, and PDF.js is configured with `enableScripting` set to true (which is the default value) and no CSP for disallowing script-src, unrestricted attacker-controlled JavaScript will be executed in the context of the hosting domain. ### Patches ### Workarounds Set `enableScripting` to `false` or set a CSP.
A type check was missing when handling fonts in PDF.js, which would allow arbitrary JavaScript execution in the PDF.js context. This vulnerability affects Firefox < 126, Firefox ESR < 115.11, and Thunderbird < 115.11.
The PDF viewer does not sufficiently sanitize PostScript calculator functions, allowing malicious JavaScript to be injected through a crafted PDF file. This JavaScript can then be run with the permissions of the PDF viewer by its worker. This vulnerability affects Firefox ESR < 52.8 and Firefox < 60.
