CVE-2026-119718: Blender Point Cache Heap Buffer Overflow Vulnerability

Sources read

Source agreement

Tam uyum

Short explanation

Blender contains a heap buffer overflow vulnerability caused by an integer overflow when reading point cache files. Attackers can supply a crafted point cache file alongside a .blend file to crash Blender or execute code as the user.

Why does it matter?

Although requiring user interaction, this vulnerability presents a high risk by allowing attackers to execute code under user privileges or crash the application through crafted point cache files.

What should be done?
