miniOrange SAML plugin under active auth bypass attacks
π Attackers are exploiting two critical authentication bypass flaws in the miniOrange SAML 2.0 Single Sign On WordPress plugin to forge SAML responses and gain administrator access. The plugin, used to integrate WordPress with corporate IdPs like Microsoft Entra ID, Okta, and Google Workspace, improperly accepts the incoming signature algorithm and mishandles OpenSSL verification errors. Fixes were released in July for free and paid editions, but incomplete vendor disclosure left many paid installations unpatched and exposed to exploitation.
