CVE-2025-3491
Published: 26 April 2025
Summary
CVE-2025-3491 is a high-severity Code Injection (CWE-94) vulnerability in Wordpress (inferred from references). Its CVSS base score is 7.2 (High).
Operationally, ranked in the top 30.8% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
The Add custom page template plugin for WordPress is vulnerable to PHP Code Injection that leads to remote code execution in all versions through 2.0.1. The flaw resides in the acpt_validate_setting function, which performs insufficient sanitization of the template_name parameter and is tracked as CWE-94.
Authenticated attackers who possess Administrator-level privileges or higher can supply a crafted template_name value to inject and execute arbitrary PHP code on the underlying server, resulting in full compromise of the WordPress site and its data.
Public references include the plugin’s SVN repository and a Wordfence vulnerability entry that detail the affected code path; administrators should replace the plugin with a patched release once one becomes available and restrict administrative accounts to trusted users.
The EPSS probability rose from a low baseline to a recorded peak of 0.0188 on 2026-02-20 before receding, indicating that exploitation interest emerged after disclosure.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Makes persistent code injection into loaded programs impossible when the executable image itself resides on hardware-protected read-only media.
Dynamically generated code can be produced and executed inside the isolated chamber, preventing host compromise from code-injection payloads.
Validates inputs used in dynamic code generation to block injected directives.
Directly prevents execution of attacker-supplied code written into data memory regions.
