Attackers can trigger an infinite loop in the JXL or HEIF image parsers by providing a crafted image containing a box with a size of zero, causing the offset to never advance and permanently hanging the application.","state":0,"publishedAt":"2026-06-10T15:31:30+00:00","modifiedAt":"2026-09-24T18:45:10.9152445+00:00","affected":[{"ecosystem":"npm","name":"image-size","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"1.2.0"},{"kind":"fixed","version":"2.0.3"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":null,"severity":null},{"system":"CVSS_V4","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"HIGH"}],"references":["https://nvd.nist.gov/vuln/detail/CVE-2025-71329","https://codeberg.org/image-size/image-size/commit/e6e83a5578961de81f6d5834d90fb7430d8f29a5","https://github.com/image-size/image-size","https://joshua.hu/image-size-infinite-loop-dos-vulnerabilities","https://web.archive.org/web/20260224152152/https://github.com/image-size/image-size/pull/439","https://www.vulncheck.com/advisories/image-size-denial-of-service-via-infinite-loop-in-jxl-heif-parser"],"sourceUrl":"https://github.com/advisories/GHSA-5p2g-fcmc-qvqq","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-5p2g-fcmc-qvqq","identifiers":["GHSA-5p2g-fcmc-qvqq","CVE-2025-71329"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
