CVE-2026-91827

7.5 highEPSS 0.3%

High (7.5). EPSS 0.3% chance of exploitation in the next 30 days.

The Ninja Forms WordPress plugin 3.15.3 does not prevent user-submitted form field values from being deserialised when an administrator later exports form submissions to CSV, allowing unauthenticated attackers to perform PHP Object Injection; if a suitable POP chain is present via another installed plugin or theme, this can lead to actions such as arbitrary file operations or remote code execution.
