{"id":"CVE-2026-112900","summary":"Pillow: Argument Injection in Ghostscript call, potentially leading into RCE","details":"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.","aliases":["BIT-pillow-2026-112900","GHSA-w889-685w-c8fh"],"modified":"2026-10-31T08:42:01.949138006Z","published":"2026-10-19T22:07:50.418Z","related":["ALSA-2026:93077","openSUSE-SU-2026:12230-1"],"database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-78","CWE-88"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/112xxx/CVE-2026-112900.json"},"references":[{"type":"WEB","url":"https://github.com/python-pillow/Pillow/releases/tag/13.0.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/112xxx/CVE-2026-112900.json"},{"type":"ADVISORY","url":"https://github.com/python-pillow/Pillow/security/advisories/GHSA-w889-685w-c8fh"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-112900"},{"type":"FIX","url":"https://github.com/python-pillow/Pillow/commit/a2c363141da31a265dd536c945677db4b64f3ec9"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/python-pillow/pillow","events":[{"introduced":"9634e437efeeda906ad6bfcc275b17732d64f32a"},{"fixed":"293218ad059d994baf1777d882911bed6a49704a"},{"fixed":"a2c363141da31a265dd536c945677db4b64f3ec9"}],"database_specific":{"extracted_events":[{"source":"CPE_RANGE","cpe":"cpe:2.3:a:python:pillow:*:*:*:*:*:*:*:*","range":[{"introduced":"2.6.0"},{"fixed":"13.0.0"}]},{"range":[{"fixed":"a2c363141da31a265dd536c945677db4b64f3ec9"}],"source":"REFERENCES_COMMIT"},{"source":"REFERENCES_TAG","original_tag":"13.0.0","range":[{"fixed":"293218ad059d994baf1777d882911bed6a49704a"}]}]}}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-112900.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V4","score":"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"}]}
