{"id":"JLSEC-2026-953","summary":"ImageMagick's Security Policy Bypass through config/policy-secure.xml via \"fd handler\" leads to stdin/stdout access","details":"ImageMagick is free and open-source software used for editing and manipulating digital images. The shipped \"secure\" security policy includes a rule intended to prevent reading/writing from standard streams. However, ImageMagick also supports fd:\u003cn\u003e pseudo-filenames (e.g., fd:0, fd:1). Prior to versions 7.1.2-15 and 6.9.13-40, this path form is not blocked by the secure policy templates, and therefore bypasses the protection goal of \"no stdin/stdout.\" Versions 7.1.2-15 and 6.9.13-40 contain a patch by including a change to the more secure policies by default. As a workaround, add the change to one's security policy manually.","modified":"2026-07-30T18:35:38.687419788Z","published":"2026-07-30T16:02:27.435Z","upstream":["CVE-2026-25966","EUVD-2026-7437","GHSA-xwc6-v6g8-pw2h"],"database_specific":{"sources":[{"modified":"2026-06-17T10:25:30.500Z","published":"2026-02-24T02:16:01.330Z","url":"https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2026-25966","html_url":"https://nvd.nist.gov/vuln/detail/CVE-2026-25966","database_specific":{"status":"Analyzed"},"id":"CVE-2026-25966","imported":"2026-07-30T14:08:45.195Z"},{"imported":"2026-07-30T14:10:38.338Z","modified":"2026-02-24T15:42:39Z","published":"2026-02-24T15:42:37Z","url":"https://api.github.com/advisories/GHSA-xwc6-v6g8-pw2h","html_url":"https://github.com/advisories/GHSA-xwc6-v6g8-pw2h","id":"GHSA-xwc6-v6g8-pw2h"},{"url":"https://euvdservices.enisa.europa.eu/api/enisaid?id=EUVD-2026-7437","html_url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-7437","id":"EUVD-2026-7437","imported":"2026-07-30T14:08:53.078Z","modified":"2026-06-23T15:48:03Z","published":"2026-02-24T01:27:53Z"}],"license":"CC-BY-4.0"},"references":[{"type":"WEB","url":"https://github.com/ImageMagick/ImageMagick/commit/8d4c67a90ae458fb36393a05c0069e9123ac174c"},{"type":"WEB","url":"https://github.com/ImageMagick/ImageMagick/security/advisories/GHSA-xwc6-v6g8-pw2h"},{"type":"WEB","url":"https://github.com/advisories/GHSA-xwc6-v6g8-pw2h"},{"type":"WEB","url":"https://github.com/dlemstra/Magick.NET/releases/tag/14.10.3"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-25966"}],"affected":[{"package":{"name":"ImageMagick_jll","ecosystem":"Julia","purl":"pkg:julia/ImageMagick_jll?uuid=c73af94c-d91f-53ed-93a7-00f77d67a9d7"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"7.1.2023+0"}]}],"database_specific":{"source":"https://github.com/JuliaLang/SecurityAdvisories.jl/tree/generated/osv/2026/JLSEC-2026-953.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
