CNA source text (English)
SAML Single Sign On 4.8.85 - 5.4.6 - Unauthenticated Administrator Account Takeover via SAML Trust Anchor Overwrite
The SAML Single Sign On WordPress plugin before 5.4.7 does not verify the signature of a SAML response before storing the certificate it carries, and offers an administrator a one-click control that promotes that stored certificate to the site's trusted signing certificate, allowing unauthenticated attackers to have a certificate of their own trusted and then authenticate as any user, including an administrator.
