A maliciously-crafted image can exploit this to cause a small image (both in terms of pixel width/height and encoded size) to make the decoder decode large amounts of compressed data.","published":"2026-07-02T21:01:22Z","modified":"2026-09-10T03:51:11.816647347Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"epss":{"score":0.00353,"percentile":0.28677,"asOf":"2026-09-15"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"golang.org/x/image","fixedVersion":"0.41.0"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-46599"},{"type":"PACKAGE","url":"https://cs.opensource.google/go/x/image"},{"type":"WEB","url":"https://go.dev/cl/759960"},{"type":"WEB","url":"https://go.dev/issue/79577"},{"type":"WEB","url":"https://groups.google.com/g/golang-announce/c/uhYX90BlBvI"},{"type":"WEB","url":"https://pkg.go.dev/vuln/GO-2026-5032"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-10T03:51:11.816647347Z"}}
