CVE-2025-10498 — Ninja Forms – The Contact Form Builder That Grows With You <= 3.12.0 - Cross-Site Request Forgery to Limited File Deletion

The Ninja Forms – The Contact Form Builder That Grows With You plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 3.12.0. This is due to missing or incorrect nonce validation when exporting CSV files. This makes it possible for unauthenticated attackers to delete those files granted they can trick an administrator into performing an action such as clicking on a link.

Low

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.

How the score was calculated

EPSS 0.2% (30-day exploitation probability)+1
Technical severity (medium)+3

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Exploitation

Not confirmed

Not in CISA KEV — an absence of record, not proof it is unexploited.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

Identify exposed assets running the affected vendor/product/version combinations (Kstover Ninja Forms – The Contact Form Builder That Grows With You, Ninjaforms Ninja Forms).
The attack is network-based and needs no privileges: restrict exposure (ACLs, VPN, WAF) until patched.
Apply the fixed version or the patch documented under Remediation.
Exploitation requires user interaction: tighten email/web filtering and warn affected users.
Search available logs for exploit probes matching the vulnerability class (csrf), errors and authentication anomalies.
