AstroBlocks is a block-first CMS for Astro projects. Prior to version 3.4.0, admin session tokens can be forged due to a hard-coded fallback JWT secret and a mismatched environment variable name. An attacker who knows the public fallback value (readable in the published package) can forge a valid session token with role: "owner" and obtain full administrative control of the CMS — creating/deleting content, users, media, redirects, and configuration. This issue has been patched in version 3.4.0.
