CVE-2026-111985

Status: DeferredLow (2.1)—
Severity2.1Low · CVSS 4.0
Exploitation probability0.55 %higher than 45% of CVEs
Active exploitationNonot in the CISA catalog
Public exploitNot knownno public code found

A vulnerability was found in AUTOMATIC1111 stable-diffusion-webui up to 1.10.1. This impacts the function read_metadata_from_safetensors of the file modules/sd_models.py of the component Metadata Extraction. The manipulation of the argument header length field results in allocation of resources. It is possible to launch the attack remotely. The exploit has been made public and could be used. The project was informed of the problem early through an issue report but has not responded yet.
