CVE-2026-119722: Blender before 4.5.15 and 5.x before 5.2.3 Heap Out-of-Bounds Access via read_struct()

HighCVSS 8.5 · v4.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 34/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.17% (FIRST EPSS).
  • Someone with local access to the system can trigger it. No account or password is required. No special conditions are required; it is repeatable.
  • Fixed version: Blender Foundation Blender 4.5.15, 5.2.3.

Low priority for now. Upgrade to Blender Foundation Blender 4.5.15, 5.2.3 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Blender before 4.5.15 and 5.x before 5.2.3 contains a heap out-of-bounds access vulnerability in read_struct() that skips size validation when a .blend file's SDNA struct layout compares equal. 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.
