SQL injection via protocol message length overflow
Published Mar 6, 2024 · Updated Dec 12, 2024
SQL injection in pgx before 4.18.2 and 5.0.0 through 5.5.3 allows remote attackers to execute injected SQL via oversized input. Protocol encoders cast a message length above 4 GB into a 32-bit field, causing PostgreSQL to parse the remaining bytes as attacker-controlled messages. Exploitation requires an application to place attacker-controlled data into one query or bind message exceeding 4 GB, enabling database reads, writes, or service interruption.

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 <4.18.2
- Affected versionversion=< 4.18.2
- Affected versionversion=>= 5.0.0, < 5.5.4
- Affected versionversion=5.0.0 <5.5.4
