{"id":"CVE-2026-120061","published":"2026-11-02T19:18:03.273","lastModified":"2026-11-02T20:17:39.313","description":"The psqlODBC parser for ODBC escape sequences in application SQL text writes the argument offsets of a {fn} escape into a fixed 16-entry stack array without a bound and does not initialize the array. An escape with too many arguments overflows the stack, and a reference to an unsupplied argument copies arbitrary bytes into the query. The copy of a {d}, {t}, {ts}, or {escape} body also writes one byte past a 128-byte stack buffer. An application that forwards untrusted SQL text to the driver exposes its process to memory corruption. Versions before psqlODBC 18.00.0006 are affected.","cvssScore":7.5,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","cwes":["CWE-121","CWE-193","CWE-457"],"vendors":[],"products":[],"references":[{"url":"https://github.com/postgresql-interfaces/psqlodbc/security/advisories/GHSA-hfm6-qfx8-v4xq","tags":[]}],"exploitRefs":[{"url":"https://github.com/postgresql-interfaces/psqlodbc/security/advisories/GHSA-hfm6-qfx8-v4xq","tags":[]}],"hasPoc":true,"ai":null}
