{"id":"CVE-2026-105691","state":"PUBLISHED","title":"Penpot: Authenticated OS Command Injection in Penpot SVG Exporter via Legacy fill-color","description":"Penpot is an open-source design and prototyping platform. Prior to 2.18.0, the SVG exporter places an attacker-controlled text object's fill-color value into a ppmcolormask command string and executes that string through child_process.exec. A user who can edit a file can store shell metacharacters in the fill color and trigger SVG export, causing commands to execute with the exporter service's privileges. The same export can be triggered through a valid public share link to a malicious file. This vulnerability is fixed in 2.18.0.","publishedAt":"2026-10-05T19:53:54.552Z","updatedAt":"2026-10-06T16:47:15.701Z","severity":{"score":9.9,"label":"Critical","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["penpot penpot"],"affected":[{"vendor":"penpot","product":"penpot","versions":[{"version":"< 2.18.0","status":"affected"}]}],"references":["https://github.com/penpot/penpot/security/advisories/GHSA-4f36-m4hj-cv86","https://github.com/penpot/penpot/pull/11272","https://github.com/penpot/penpot/commit/aa3bc1ae984577f0354d4270d2546e15985f4bcf","https://github.com/penpot/penpot/releases/tag/2.18.0"],"weaknesses":["CWE-78"],"ingestedAt":"2026-10-29T20:10:23.711Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/105xxx/CVE-2026-105691.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-105691","state":"PUBLISHED","datePublished":"2026-10-05T19:53:54.552Z","dateUpdated":"2026-10-06T16:47:15.701Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-10-05T17:48:58.626Z"},"containers":{"cna":{"title":"Penpot: Authenticated OS Command Injection in Penpot SVG Exporter via Legacy fill-color","descriptions":[{"lang":"en","value":"Penpot is an open-source design and prototyping platform.
