{"id":"CVE-2026-107735","published":"2026-10-08T23:16:59.403","lastModified":"2026-10-09T16:17:24.527","description":"SumatraPDF is a multi-format reader for Windows. In 3.6.1 and earlier, InitializePolicies() starts the sumatrapdfrestrict.ini path with gPolicyRestrictions set to Perm::All and only ORs permission bits, so the INI file never revokes permissions. Deploying SumatraPDF with this INI file, including a malformed file or zero-valued permission settings, can silently bypass configured disk, network, printing, registry, clipboard, preference, and fullscreen restrictions. The -restrict command-line path works correctly and is not affected. No fixed version is available as of this review.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-636"],"vendors":[],"products":[],"references":[{"url":"https://github.com/sumatrapdfreader/sumatrapdf/commit/f72948b59405d3ddba527789898050ef411d0bb8","tags":[]},{"url":"https://github.com/sumatrapdfreader/sumatrapdf/security/advisories/GHSA-crhm-w5qr-wjj4","tags":[]},{"url":"https://github.com/sumatrapdfreader/sumatrapdf/security/advisories/GHSA-crhm-w5qr-wjj4","tags":[]}],"exploitRefs":[{"url":"https://github.com/sumatrapdfreader/sumatrapdf/commit/f72948b59405d3ddba527789898050ef411d0bb8","tags":[]},{"url":"https://github.com/sumatrapdfreader/sumatrapdf/security/advisories/GHSA-crhm-w5qr-wjj4","tags":[]},{"url":"https://github.com/sumatrapdfreader/sumatrapdf/security/advisories/GHSA-crhm-w5qr-wjj4","tags":[]}],"hasPoc":true,"ai":null}
