CVE-2026-119720

Blender before 4.5.15 and 5.x before 5.2.3 Out-of-Bounds Read via GLOB Block

Published Oct 30, 2026 CVSS 4.0 · 6.8 Medium EPSS < 1% KEV · Not listed

Description

Blender before 4.5.15 and 5.x before 5.2.3 contains a heap out-of-bounds read vulnerability in read_file_dna() that reads a GLOB block field without validating its declared length. Attackers can supply a crafted .blend file with a truncated GLOB block that, when opened, triggers the out-of-bounds read and crashes Blender.
