Cross-query data disclosure via cancellation race
Published Aug 7, 2025 · Updated Nov 4, 2025
Race condition in Go database/sql before 1.23.12 and 1.24.0 through 1.24.5 allows attackers to cause cross-query result disclosure. Rows.Scan did not hold its close lock throughout conversion of driver-owned row data; during the race, cancellation closes driver.Rows while Scan is still reading that memory. Reachability requires cancellation during Scan while other queries run in parallel; outcomes are another query’s data, corrupted results, or an error.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=0 <1.23.12
- Affected versionversion=1.24.0 <1.24.6
