{"id":"CVE-2026-107732","state":"PUBLISHED","title":"SumatraPDF: Markup/command-link injection into UI notification text","description":"SumatraPDF is a multi-format reader for Windows. In 3.6.1 and earlier, untrusted document paths and PDF link targets are interpolated into notification text that ParseTip() interprets as trusted tip markup. When a user clicks an injected link, ExecuteTipLink() dispatches its CmdExec command and can execute an attacker-selected local program in the user's context. No broader impact is claimed beyond the advisory-supported conditions. No fixed version is available as of this review.","publishedAt":"2026-10-08T22:22:11.879Z","updatedAt":"2026-10-13T16:28:47.961Z","severity":{"score":8.4,"label":"High","version":"4.0","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["sumatrapdfreader sumatrapdf"],"affected":[{"vendor":"sumatrapdfreader","product":"sumatrapdf","versions":[{"version":"<= 3.6.1","status":"affected"}]}],"references":["https://github.com/sumatrapdfreader/sumatrapdf/security/advisories/GHSA-2wv2-qm2f-vmxh","https://github.com/sumatrapdfreader/sumatrapdf/commit/8b680387ed69e3504ef296e09d6e032f81076af8"],"weaknesses":["CWE-94"],"ingestedAt":"2026-10-29T20:10:23.711Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/107xxx/CVE-2026-107732.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-107732","state":"PUBLISHED","datePublished":"2026-10-08T22:22:11.879Z","dateUpdated":"2026-10-13T16:28:47.961Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-10-08T17:21:52.976Z"},"containers":{"cna":{"title":"SumatraPDF: Markup/command-link injection into UI notification text","descriptions":[{"lang":"en","value":"SumatraPDF is a multi-format reader for Windows.
