CVE-2026-64682

Summary

AstroBlocks prior to v3.4.0 uses a hard-coded JWT secret as a fallback, and due to an environment variable naming mismatch, attackers can bypass authentication by forging valid admin session tokens with 'owner' privileges. This allows full administrative control over the CMS, including content, user, and configuration manipulation.

Exploitability

Exploitation is trivial for attackers who know the publicly exposed fallback JWT secret (published in the package source); no authentication or user interaction is required.

Blast radius

Successful exploitation grants full administrative access to the CMS, enabling complete compromise of content integrity, user data, and system configuration across all affected deployments.

Detection

No reliable host or network indicator is derivable from the published description.

Prioritized remediation

Upgrade to AstroBlocks version 3.4.0 or later, which patches the hard-coded secret and corrects the environment variable handling.
