{"id":"CVE-2026-88345","published":"2026-09-22T20:17:10.613","lastModified":"2026-09-24T21:08:55.030","description":"An out-of-bounds read vulnerability exists in the schema lexer of flatcc 4c3b999e. When an exact-length FlatBuffers schema ends with an unterminated quotation mark, the C-string scanning logic in lex() dereferences the input pointer after it has reached the end of the buffer. A specially crafted schema can trigger a one-byte heap buffer over-read, resulting in application crash and denial of service.","cvssScore":7.5,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","cwes":["CWE-125"],"vendors":[],"products":[],"references":[{"url":"https://github.com/dvidelabs/flatcc/issues/385","tags":[]},{"url":"https://github.com/jimjag/flatcc/commit/8581715e8ec4e5de8eea9fd6dad949e4dd7d0fa0","tags":[]},{"url":"https://github.com/dvidelabs/flatcc/issues/385","tags":[]}],"exploitRefs":[{"url":"https://github.com/dvidelabs/flatcc/issues/385","tags":[]},{"url":"https://github.com/jimjag/flatcc/commit/8581715e8ec4e5de8eea9fd6dad949e4dd7d0fa0","tags":[]},{"url":"https://github.com/dvidelabs/flatcc/issues/385","tags":[]}],"hasPoc":true,"ai":null}
