{"id":"CVE-2026-16651","published":"2026-09-21T12:17:10.167","lastModified":"2026-09-21T16:17:07.067","description":"temporalio/sqlparser can panic when Parse, ParseStrictDDL, or ParseNext processes a MySQL version comment whose contents are empty or consist only of one to five decimal digits. ExtractMysqlComment does not check the -1 result returned by strings.IndexFunc before using it as a slice boundary. The resulting Go runtime panic propagates unless the caller recovers it on the parsing goroutine, so applications that parse attacker-controlled SQL can terminate. Temporal Server exposes the affected parser through ListWorkers. When that API is enabled, an authenticated caller with namespace read permission can submit a malformed query that terminates the receiving Matching process. Repeated requests can sustain a denial of service. The issue affects availability only; no confidentiality or integrity impact was identified.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-129"],"vendors":[],"products":[],"references":[{"url":"https://github.com/temporalio/sqlparser/commit/74181ffcbaaf0c52faa925f4cf27ed6c0c2be86f","tags":[]},{"url":"https://github.com/temporalio/sqlparser/pull/5","tags":[]},{"url":"https://github.com/temporalio/sqlparser/tree/v0.1.0","tags":[]},{"url":"https://github.com/temporalio/temporal/pull/11090","tags":[]},{"url":"https://github.com/temporalio/temporal/pull/11190","tags":[]},{"url":"https://github.com/temporalio/temporal/releases/tag/v1.30.7","tags":[]},{"url":"https://github.com/temporalio/temporal/releases/tag/v1.31.3","tags":[]}],"exploitRefs":[{"url":"https://github.com/temporalio/sqlparser/commit/74181ffcbaaf0c52faa925f4cf27ed6c0c2be86f","tags":[]},{"url":"https://github.com/temporalio/sqlparser/pull/5","tags":[]},{"url":"https://github.com/temporalio/sqlparser/tree/v0.1.0","tags":[]},{"url":"https://github.com/temporalio/temporal/pull/11090","tags":[]},{"url":"https://github.com/temporalio/temporal/pull/11190","tags":[]},{"url":"https://github.com/temporalio/temporal/releases/tag/v1.30.7","tags":[]},{"url":"https://github.com/temporalio/temporal/releases/tag/v1.31.3","tags":[]}],"hasPoc":true,"ai":null}
