Details

react-pdf vulnerable to arbitrary JavaScript execution upon opening a malicious PDF with PDF.js ### Summary If PDF.js is used to load a malicious PDF, and PDF.js is configured with `isEvalSupported` set to `true` (which is the default value), unrestricted attacker-controlled JavaScript will be executed in the context of the hosting domain. ### Patches [This patch](https://github.com/wojtekmaj/react-pdf/commit/671e6eaa2e373e404040c13cc6b668fe39839cad) forces `isEvalSupported` to `false`, removing the attack vector. ### Workarounds Set `options.isEvalSupported` to `false`, where `options` is `Document` component prop. ### References - [GHSA-wgrm-67xf-hhpq](https://github.com/mozilla/pdf.js/security/advisories/GHSA-wgrm-67xf-hhpq) - https://github.com/mozilla/pdf.js/pull/18015 - https://github.com/mozilla/pdf.js/commit/85e64b5c16c9aaef738f421733c12911a441cec6 - https://bugzilla.mozilla.org/show_bug.cgi?id=1893645
