CVE-2026-22202
wpDiscuz before 7.6.47 contains a cross-site request forgery vulnerability that allows attackers to delete all comments associated with an email address by crafting a malicious GET request with a valid HMAC key.
Does this matter?
Lower severity and a low EPSS score (0.17%). Track it; it rarely justifies an emergency change on its own.
