CVE-2026-47749 (opens in a new tab)How to fix?
Upgrade leejet/stable-diffusion.cpp to version master-584-0a7ae07 or higher.
Overview
Affected versions of this package are vulnerable to Out-of-bounds Write via the SHORT_BINUNICODE parsing process for PyTorch checkpoint files. An attacker can cause heap corruption or potentially achieve code execution by supplying a crafted .ckpt file containing a malicious opcode length field. This is only exploitable if an application loads a .ckpt file from an untrusted source.
Workaround
This vulnerability can be mitigated by only loading checkpoint files from trusted sources and preferring safer formats such as .safetensors.
