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.","state":0,"publishedAt":"2026-10-08T22:26:00.405+00:00","modifiedAt":"2026-10-09T15:24:14.433+00:00","affected":[{"ecosystem":"Vendor product","name":"sumatrapdf","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"sumatrapdfreader\",\n                    \"product\": \"sumatrapdf\",\n                    \"versions\": [\n                        {\n                            \"version\": \"<= 3.6.1\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":5.4,"severity":"MEDIUM"}],"references":["https://github.com/sumatrapdfreader/sumatrapdf/security/advisories/GHSA-crhm-w5qr-wjj4","https://github.com/sumatrapdfreader/sumatrapdf/commit/f72948b59405d3ddba527789898050ef411d0bb8"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-107735","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-107735","identifiers":["CVE-2026-107735"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
