CVE-2025-26924

Vulnerability

Overview The Ohio Extra plugin for WordPress (versions up to and including 3.4.7) contains an Improper Control of Generation of Code (Code Injection) vulnerability [1]. This flaw allows an attacker to inject arbitrary shortcodes, enabling code injection within the affected WordPress installations.

Exploitation

Attackers can exploit this vulnerability without authentication by sending specially crafted requests containing malicious shortcodes. The vulnerability is classified as content injection (CAPEC-242), which enables the injection of arbitrary content into posts or pages [1]. No special privileges or complex conditions are required for exploitation.

Impact

Successful exploitation allows an attacker to inject their own content into the target website's pages and posts. This can be abused to insert phishing pages or other malicious content, potentially compromising visitors' data or credentials. The vulnerability is considered moderately dangerous and is expected to be used in automated mass-exploit campaigns against thousands of sites [1].

Mitigation

The vendor has not released a patch; the recommended immediate action is to update the plugin to a version beyond 3.4.7 once available. If updating is not immediately possible, users should consult their hosting provider or web developer for mitigation strategies [1].
