High CVSS 7.5

CVE-2026-14603

The WowOptin: Next-Gen Popup Maker WordPress plugin before 1.4.38 does not have proper authorization on a REST endpoint, allowing unauthenticated users to disable all of the site's opt-in forms and insert new template-based opt-in rows into the database.

What this means

Exposure
Exploitable remotely over the network, without authentication and with no action from the victim.
Impact
An attacker can read sensitive data.
Weakness
Access control is applied incorrectly, leaving a protected resource reachable without the required rights.
Likelihood
Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.

What to doFold into the next patch cycle. Start with the instances exposed to the internet.
