Attackers can supply a crafted .blend file with short blocks so field reads, writes, and pointer dereferences overrun heap memory, causing crashes or code execution.","published":"2026-10-30T16:17:55.907","modified":"2026-10-30T16:17:55.907","cvss":{"score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://projects.blender.org/blender/blender"},{"type":"WEB","url":"https://projects.blender.org/blender/blender/commit/7de4986e74ed47f67e78eb4b76609bb6d1ae8a0e"},{"type":"WEB","url":"https://projects.blender.org/blender/blender/commit/c5d6faf04bf3f17efb6c404896ef0e7427784da5"},{"type":"WEB","url":"https://projects.blender.org/blender/blender/pulls/164279"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/blender-before-4.5.15-and-5-x-before-5.2.3-heap-out-of-bounds-access-via-read-struct"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-10-30T16:17:55.907"}}
