Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Auth0 WordPress plugin (auth0/wordpress) versions 5.0.0-BETA0 through 5.4.x, when built on Auth0-PHP SDK versions 8.0.0 through 8.17.0, fail to properly validate token audience, so applications may accept ID tokens as access tokens. The source does not describe the attacker's required position or the exact impact beyond this. Upgrade the Auth0 WordPress plugin to version 5.5.0 or later.
