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.","cvss_v4":{"vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":8.5},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-125"],"references":["https://projects.blender.org/blender/blender","https://projects.blender.org/blender/blender/commit/7de4986e74ed47f67e78eb4b76609bb6d1ae8a0e","https://projects.blender.org/blender/blender/commit/c5d6faf04bf3f17efb6c404896ef0e7427784da5","https://projects.blender.org/blender/blender/pulls/164279","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"],"products":[],"source":"nvd","synced_at":"2026-10-30T16:41:48.501372702+00:00"},"epss":null,"kev":null,"osv":[],"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).
