CVE-2026-85788: Aws Labs MySQL Mcp Server

Medium severity, CVSS 5.5. EPSS: 0.2% chance of exploitation in the next 30 days.

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.

Affected products

• Aws Aws Labs MySQL Mcp Server: up to and including 1.0.21
