Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 35.7th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Deeper analysis
CVE-2025-1770, published on 2025-03-20, is a Local File Inclusion (LFI) vulnerability (CWE-22) in the Event Manager, Events Calendar, Tickets, Registrations – Eventin plugin for WordPress. It affects all versions up to and including 4.0.24 and stems from improper handling of the 'style' parameter, which allows the inclusion and execution of arbitrary files on the server. The vulnerability carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).
Authenticated attackers with Contributor-level access or higher can exploit this issue over the network with low complexity and no user interaction. By manipulating the 'style' parameter, they can include arbitrary files, execute PHP code within them, bypass access controls, obtain sensitive data, or achieve code execution, particularly if images or other "safe" file types containing PHP payloads can be uploaded and included.
Advisories and patches are detailed in the provided references, including Wordfence's threat intelligence report and WordPress plugin trac entries. Specific code locations in events-calendar.php (line 715) and tab-1.php (line 53) from version 4.0.24 are implicated, with changeset 3257023 indicating the applied fix.

Mitigating Controls (NIST 800-53 r5) AI
Directly mitigates CVE-2025-1770 by identifying, prioritizing, and applying the vendor patch that corrects the improper 'style' parameter handling in the Eventin plugin.
Requires validation of the 'style' parameter inputs to reject arbitrary file paths, preventing local file inclusion and subsequent PHP code execution.
Enforces least privilege for Contributor-level users, limiting the scope and impact of exploitation even if the LFI is triggered.
