Authenticated RCE via unchecked LIMIT and KNN bounds
Published Jan 8, 2025 · Updated Jan 8, 2025
Integer overflow in affected Redis RediSearch 2.x releases allows remote authenticated users to execute code via crafted LIMIT or KNN arguments. The query and aggregation paths accept oversized LIMIT offsets and counts or KNN K values, and subsequent size calculations wrap before heap writes. Exploitation requires authenticated Redis access and affected-command permission; successful heap corruption executes code in the Redis server context.

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=>= 2.0.0, < 2.6.24
- Affected versionversion=>= 2.10.0, < 2.10.10
