Unauthenticated remote attackers can supply a crafted ICO image to corrupt adjacent heap chunk metadata, triggering a glibc abort that crashes the worker.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":8.7,"severity":"high","source":"CNA: VulnCheck","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","version":"4.0"},{"score":7.5,"severity":"high","source":"CNA: VulnCheck","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"}],"modifiedAt":1794101919703,"publishedAt":1794101919703,"references":[{"source":"CNA: VulnCheck","tags":["vendor-advisory"],"url":"https://github.com/imgproxy/imgproxy/security/advisories/GHSA-494m-4556-wf5p"},{"source":"CNA: VulnCheck","tags":["third-party-advisory"],"url":"https://www.vulncheck.com/advisories/imgproxy-before-4.0.17-out-of-bounds-write-in-ico-loader"}],"remediation":[],"revision":"1cc419b67f9fe10ee84c719a15659177e977c830e81814467e911cc98304c3cc","sources":[{"modifiedAt":1794101919703,"name":"CNA: VulnCheck","retrievedAt":1794103854608,"url":"https://www.cve.org/CVERecord?id=CVE-2026-123615"}],"ssvc":null,"status":"published","title":"imgproxy before 4.0.17 Out-of-Bounds Write in ICO Loader","updatedAt":1794103854608}
