SQL injection via PDO SQLite length overflow
Published Feb 12, 2025 · Updated Feb 13, 2025
SQL injection in PDO_SQLITE in PHP before 8.0.27, 8.1.15, or 8.2.2 in each supported branch allows remote attackers to alter queries. The PDO_SQLITE quoter passes a length derived from an unrestricted 64-bit string to sqlite3_snprintf's int parameter, causing integer overflow and malformed output. Exploitation requires an application to pass attacker-controlled input exceeding normal memory and request-size limits into PDO::quote() and then interpolate its result into SQL.

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=8.0.x <8.0.27
- Affected versionversion=8.1.x <8.1.15
- Affected versionversion=8.2.x <8.2.2
