In versions prior to master-584-0a7ae07, the pickle .ckpt parser in src/model.cpp contained a heap buffer overflow vulnerability in the GLOBAL opcode handler. The issue was caused by missing validation when searching for newline-delimited fields. A crafted .ckpt file without the expected newline could cause the parser to use -1 as a copy length, resulting in immediate heap corruption. The attack requires the victim or application to load a .ckpt file from an untrusted source, such as a downloaded model from a model sharing site. The issue has been resolved in version master-584-0a7ae07. If developers are unable to immediately update their applications they can work around this issue by following these instructions: do not load .ckpt checkpoint files from untrusted sources, and prefer trusted model sources and safer formats such as .safetensors where possible."}], "lastModified": "2026-06-25T13:55:19.500", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:leejet:stable-diffusion.cpp:*:*:*:*:*:c\\+\\+:*:*", "vulnerable": true, "matchCriteriaId": "EF9A4C1B-8396-48E6-8E46-3A3767DA17FC", "versionEndExcluding": "master-584-0a7ae07"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
