Summary

CVE-2025-30831 is a high-severity PHP Remote File Inclusion (CWE-98) vulnerability. Its CVSS base score is 7.5 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 16.6% of CVEs by exploit likelihood; 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-2025-30831 is a PHP Local File Inclusion vulnerability arising from improper control of filenames in include/require statements. It affects the Themify Event Post WordPress plugin developed by themifyme, with all versions through 1.3.2 impacted. The flaw is tracked under CWE-98 and carries a CVSS 3.1 score of 7.5.

An authenticated attacker with low privileges can supply a crafted filename parameter over the network to force inclusion of arbitrary local files on the server. Successful exploitation can yield disclosure of sensitive information as well as the ability to execute arbitrary code, resulting in high impact to confidentiality, integrity, and availability despite the noted attack complexity.

The public advisory published via PatchStack identifies the issue in the Themify Event Post plugin and points administrators to the need for an update once a fixed release becomes available.

EPSS for the CVE remains low and unchanged at 0.0186 with no observed rise after disclosure.

Affected Assets

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly mitigates the improper filename control in PHP include/require by enforcing validation of user-supplied inputs used for file inclusion in the Themify Event Post plugin.

prevent

Requires timely identification, reporting, and patching of the LFI vulnerability in Themify Event Post plugin versions through 1.3.2 to eliminate the exploitable flaw.

prevent

Enforces secure configuration settings for PHP and web server environments, such as open_basedir restrictions and disabling dangerous includes, to limit local file access even if input validation fails.
