Summary
StarRocks through 4.0.13 contains an authentication bypass vulnerability in five REST handler classes that override execute() directly instead of implementing executeWithoutPassword(). Attackers can access six unauthenticated endpoints on the frontend HTTP port to disclose cluster topology, database metadata, JVM statistics, and version information without credentials.

Inferred packages
No advisory lists a package for this vulnerability yet. The CVE names these as products and links their GitHub repository, and the package registry names the same repository, so they are probably the affected packages. Low confidence: the versions are the CVE’s own for the product, and a stack check reports the package as unchecked when there are none.
