What is CVE-2026-108685?
The WP Post Author plugin for WordPress allows unauthenticated users to exploit a vulnerability where they can update the display name, nickname, and website of the first user account—typically the administrator's account—during front-end registration. This occurs without validating that the user's account was created before making these changes. Versions prior to 4.2.0 are susceptible to this issue, making it essential for users to upgrade to mitigate potential risks.
