{"id":"CVE-2026-112900","state":"PUBLISHED","title":"Pillow: Argument Injection in Ghostscript call, potentially leading into RCE","description":"Pillow is a Python imaging library. From 2.6.0 until 13.0.0, Pillow is vulnerable to argument injection when invoking Ghostscript for EPS input. EpsImagePlugin.Ghostscript passes a caller-controlled input filename after -f without converting it to a safe absolute path, so a name beginning with a hyphen can be interpreted as a Ghostscript option. An attacker who controls the filename can inject Ghostscript arguments. Arbitrary command execution specifically requires a leading @ argument-file filename and control of the referenced text file containing additional Ghostscript arguments; the reported chain reproduces with the default -dSAFER invocation. This issue is fixed in version 13.0.0.","publishedAt":"2026-10-19T22:07:50.418Z","updatedAt":"2026-10-20T14:43:44.563Z","severity":{"score":9.2,"label":"Critical","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["python-pillow Pillow"],"affected":[{"vendor":"python-pillow","product":"Pillow","versions":[{"version":">= 2.6.0, < 13.0.0","status":"affected"}]}],"references":["https://github.com/python-pillow/Pillow/security/advisories/GHSA-w889-685w-c8fh","https://github.com/python-pillow/Pillow/commit/a2c363141da31a265dd536c945677db4b64f3ec9","https://github.com/python-pillow/Pillow/releases/tag/13.0.0"],"weaknesses":["CWE-78","CWE-88"],"ingestedAt":"2026-10-29T20:10:43.281Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/112xxx/CVE-2026-112900.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-112900","state":"PUBLISHED","datePublished":"2026-10-19T22:07:50.418Z","dateUpdated":"2026-10-20T14:43:44.563Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-10-19T20:16:09.857Z"},"containers":{"cna":{"title":"Pillow: Argument Injection in Ghostscript call, potentially leading into RCE","descriptions":[{"lang":"en","value":"Pillow is a Python imaging library.
