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.","published_at":"2026-06-16T18:17:41.349000Z","last_modified_at":null,"cvss_v3_score":7.8,"cvss_v3_vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","cvss_v3_severity":"HIGH","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-787"],"nvd_references":["https://github.com/leejet/stable-diffusion.cpp/security/advisories/GHSA-v37x-jwp7-mcvc","https://github.com/leejet/stable-diffusion.cpp/pull/1443","https://github.com/leejet/stable-diffusion.cpp/commit/0a7ae07f948eff4611968a65a22bd7c7031ad74f"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-28T23:30:41.527238Z"},"effective_severity":"HIGH","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"L","value_label":"Local"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"R","value_label":"Required"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"H","value_label":"High"},{"metric":"I","name":"Integrity","value":"H","value_label":"High"},{"metric":"A","name":"Availability","value":"H","value_label":"High"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"leejet","vendor_name":"leejet","product_slug":"stable-diffusion.cpp","product_name":"stable-diffusion.cpp","version_start":"< master-584-0a7ae07","version_start_inclusive":true,"version_end":"< master-584-0a7ae07","version_end_inclusive":true,"cpe23_uri":"cve5:leejet:stable-diffusion.cpp:< master-584-0a7ae07:< master-584-0a7ae07"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/leejet/stable-diffusion.cpp/security/advisories/GHSA-v37x-jwp7-mcvc","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/leejet/stable-diffusion.cpp/pull/1443","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/leejet/stable-diffusion.cpp/commit/0a7ae07f948eff4611968a65a22bd7c7031ad74f","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2026-06-16T18:17:41.349000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:54:57.553414Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:54:57.553414Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:54:57.553414Z","label":"CVSS score revised","source":"cvelistv5"}]}
