What is CVE-2026-91153?

The Everest Forms plugin for WordPress is susceptible to a vulnerability that allows attackers to access sensitive information from post meta values. This issue affects all versions up to and including 3.6.2, enabling unauthenticated users to extract potentially sensitive data such as license keys, API tokens, and SMTP credentials through form submission notifications or stored entries. The vulnerability arises from the public rendering of the submission nonce in each embedded form, and an exploit can be executed anonymously, requiring no prior authentication. It is crucial for users to update to the latest version to mitigate the risks associated with this vulnerability.
