It is attacked with local access.

Am I affected by CVE-2026-119722?

Check whether you run Blender Foundation Blender at an affected version. Junglewise does that check for you around the clock: connect your code, cloud and domains, and it matches new vulnerabilities like this one against what you actually run and tells you when one reaches you.

CVE-2026-119722: Blender heap out-of-bounds access in SDNA struct parsing

CVE-2026-119722 · Severity: high · CVSS 7.8 · Published 2026-10-30

Blender, a widely-used 3D modeling and animation software, contains a memory safety vulnerability in how it parses .blend project files. An attacker can craft a malicious .blend file that causes Blender to read or write beyond allocated memory, leading to application crashes or potentially allowing code execution on a user's system.

Technologies: Blender Foundation Blender. Vendors: Blender Foundation.

How to fix

Fixed in: Blender 4.5.15, 5.2.3

Technical details

The vulnerability exists in the read_struct() function which fails to validate the size of data blocks when the SDNA struct layout matches between the file and runtime. An attacker can craft a .blend file with intentionally short data blocks that cause field reads, writes, and pointer dereferences to overrun heap memory boundaries. This out-of-bounds access can result in denial of service or arbitrary code execution depending on heap layout and attacker capabilities.

Affected products

Blender Foundation Blender before 4.5.15 and 5.0 before 5.2.3
