Prior to versions 3.0.16.0 and 3.1.11.0, processing a crafted BMP file through oiiotool or an application linked to OpenImageIO can reach BMP palette handling in src/bmp.imageio/bmpinput.cpp with an empty color table. BmpInput::read_native_scanline then performs an invalid palette read while decoding an RLE-compressed scanline, causing a process crash and denial of service. This issue is fixed in versions 3.0.16.0 and 3.1.11.0.","state":0,"publishedAt":"2026-09-17T21:33:44.377+00:00","modifiedAt":"2026-09-24T20:48:06.366+00:00","affected":[{"ecosystem":"Vendor product","name":"OpenImageIO","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"AcademySoftwareFoundation\",\n                    \"product\": \"OpenImageIO\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 3.0.16.0\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 3.1.0.0, < 3.1.11.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","score":5.5,"severity":"MEDIUM"}],"references":["https://github.com/AcademySoftwareFoundation/OpenImageIO/security/advisories/GHSA-q3c7-3225-66h7","https://github.com/AcademySoftwareFoundation/OpenImageIO/pull/5030","https://github.com/AcademySoftwareFoundation/OpenImageIO/commit/91500ed58ce927b7e710c6bbc3b7f795bb0791b5","https://github.com/AcademySoftwareFoundation/OpenImageIO/commit/be984856e315e0a82cd866745b544c8c4cb8bd45","https://github.com/AcademySoftwareFoundation/OpenImageIO/commit/ee3370d004d5895554239b4302c59eedb721f086","https://github.com/AcademySoftwareFoundation/OpenImageIO/releases/tag/v3.0.16.0","https://github.com/AcademySoftwareFoundation/OpenImageIO/releases/tag/v3.1.11.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-50291","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-50291","identifiers":["CVE-2026-50291"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
