Incomplete list of disallowed inputs in awslabs mysql-mcp-server

Assigner: AMZN
Reserved: 04.09.2026 Published: 09.09.2026 Updated: 09.09.2026

Incomplete list of disallowed inputs in the mutable SQL detector component in Amazon awslabs mysql-mcp-server might allow context-dependent actors to bypass the read-only enforcement gate and reach file-read and file-write SQL sinks via SQL inline comments that the regex engine does not treat as whitespace.

To remediate this issue, users should upgrade to version 1.0.23.
