Machine-written summary

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

Formie (Packagist verbb/formie) versions below 2.2.23 and from 3.0.0 up to 3.1.31 are affected. An authenticated user who lacks the proper form integration permissions can call the form-settings integration action, which applies attacker-supplied settings such as the API URL to a configured integration, causing the server to send stored API keys or OAuth tokens to an attacker-controlled host and return the response. Upgrade to 3.1.31 (Craft 5) or 2.2.23 (Craft 4); the source notes that restricting front-end registration and CP access only reduces risk until the upgrade is applied.
