Wpmu Dev Dashboard
Monthly
Authentication bypass in the WPMU DEV Dashboard WordPress plugin (all versions through 5.0.1) lets an unauthenticated attacker forge a valid administrator session by abusing an HMAC signature-verification flaw in the Hub SSO login flow. Because the signing routine in the unauthenticated wdpsso_step1 action covers a different, unseparated field concatenation than the verifier in wdpsso_step2, an attacker can obtain a legitimately signed token and replay it with fields rearranged to authenticate as admin. No public exploit is identified at time of analysis, but the network-reachable, unauthenticated nature and 9.8 CVSS make this a high-priority patch item.
Authentication bypass in WPMU DEV Dashboard (WordPress plugin) versions up to and including 5.0.0 enables unauthenticated remote attackers to invoke privileged Hub actions - including remote code execution by installing a plugin from an attacker-controlled URL, takeover of an administrator account via SSO, deletion of plugins and themes, and forced WordPress core upgrades - on any site not yet connected to the WPMU DEV Hub. The default post-installation state is unconnected, meaning every fresh installation is immediately exposed until Hub onboarding is completed. No public exploit or CISA KEV listing has been identified at time of analysis, though the impact ceiling (unauthenticated RCE) and the breadth of default-state exposure make this a high-priority remediation target.
