Binding parameter number 32768 wraps that count to -32768. Binding parameter 32769 then writes about 2.5 MB of zeros starting 1.25 MB before the binding array, which crashes the application or leaves it running on a corrupted heap. Applications that build parameter lists from untrusted input, such as an IN (?, ?, ...) list, are exposed. Versions before psqlODBC 18.00.0005 are affected.","published":"2026-10-12T18:17:23.000Z","lastModified":"2026-10-16T18:17:31.000Z","status":"Awaiting Analysis","sourceIdentifier":"f86ef6dc-4d3a-42ad-8f28-e6d5547a5007","cvss":{"version":"3.1","score":5.9,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H"},"cwe":["CWE-124","CWE-190"],"affected":[],"epss":{"score":0.00222,"percentile":0.12737,"date":"2026-10-26","history":[{"date":"2026-10-13","score":0.00222,"percentile":0.11856}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.22%).
