High CVSS 8.1

CVE-2026-14553

NVD analysis in progress

The zportals WordPress plugin before 6.3.4 does not properly validate uploaded files, trusting the client-supplied content type and preserving the original file extension, allowing any authenticated user (Subscriber or higher) to upload arbitrary PHP files and achieve remote code execution.

What this means

Exposure
Exploitable remotely over the network, with an ordinary user account and with no action from the victim.
Impact
An attacker can read sensitive data and modify or destroy data.
Weakness
Upload accepts a dangerous file type, often one the server will execute.
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.

Read automatically from the CVSS vector, the weakness type (CWE) and the EPSS score. The technical description above remains the one published by NIST.
