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":"2026-06-10T13:04:30.38+00:00","modifiedAt":"2026-11-08T14:00:26.865+00:00","affected":[{"ecosystem":"Vendor product","name":"image-size","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"image-size\",\n                    \"product\": \"image-size\",\n                    \"repo\": \"https://github.com/image-size/image-size\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"1.1.0\",\n                            \"lessThanOrEqual\": \"1.2.1\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"2.0.0\",\n                            \"lessThanOrEqual\": \"2.0.2\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\",\n                    \"packageURL\": \"pkg:npm/image-size\"\n                }"}],"metrics":[{"system":"CVSS 4.0","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":8.7,"severity":"HIGH"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5,"severity":"HIGH"}],"references":["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://www.cve.org/CVERecord?id=CVE-2025-71329","license":"CVE Program Terms of Use","key":"cve-program:CVE-2025-71329","identifiers":["CVE-2025-71329"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
