{"id":"CVE-2026-107802","state":"PUBLISHED","title":"SumatraPDF — Windows command-line argument injection in AI selection-translate","description":"SumatraPDF is a multi-format reader for Windows. In 3.6.1 and earlier, src/SelectionTranslate.cpp embeds selected or pasted translation text in quoted Windows command lines using incomplete quote-only escaping. The affected BuildGrokTranslateCmdLineTemp(), BuildClaudeTranslateCmdLineTemp(), and BuildCodexTranslateCmdLineTemp() functions can allow attacker-controlled text to inject model, working-directory, approval, or sandbox-bypass flags when the corresponding agentic CLI backend is installed and used. No broader impact is claimed beyond the advisory-supported conditions. No fixed version is available as of this review.","publishedAt":"2026-10-08T22:36:36.409Z","updatedAt":"2026-10-09T19:09:00.523Z","severity":{"score":7.1,"label":"High","version":"4.0","vector":"CVSS:4.0/AV:L/AC:L/AT:P/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-xvxg-cwmx-hr7j","https://github.com/sumatrapdfreader/sumatrapdf/commit/6b88a751ab34a28bafca3bdd635aaa2f4c1e06b6"],"weaknesses":["CWE-88"],"ingestedAt":"2026-10-29T20:10:23.711Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/107xxx/CVE-2026-107802.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-107802","state":"PUBLISHED","datePublished":"2026-10-08T22:36:36.409Z","dateUpdated":"2026-10-09T19:09:00.523Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-10-08T21:23:59.819Z"},"containers":{"cna":{"title":"SumatraPDF — Windows command-line argument injection in AI selection-translate","descriptions":[{"lang":"en","value":"SumatraPDF is a multi-format reader for Windows.
