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." } ], "source": { "advisory": "GHSA-mfcg-m7j5-7v72", "discovery": "UNKNOWN" } } } }
