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.","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":8.7},"cvss_v3":{"version":"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},"cwes":["CWE-835"],"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"],"products":["image-size:image-size"],"source":"nvd","synced_at":"2026-10-19T22:38:48.522727527+00:00"},"epss":{"cve":"CVE-2025-71329","score":0.0043,"percentile":0.37026,"date":"2026-10-26"},"kev":null,"osv":[{"id":"GHSA-5p2g-fcmc-qvqq","url":"https://osv.dev/vulnerability/GHSA-5p2g-fcmc-qvqq","summary":"image-size: JXL and HEIF parsers allow denial of service through infinite loops","modified":"2026-09-24T18:45:10.915244487Z","packages":[{"ecosystem":"npm","name":"image-size","purl":"pkg:npm/image-size","ranges":[">=1.2.0 <2.0.3"],"fixed":["2.0.3"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
