CVE-2026-10724 in Reviews Feed Plugin
Summary
by MITRE • 07/20/2026
The Reviews Feed WordPress plugin before 2.6.5 does not neutralize WordPress shortcodes contained in third-party review content before rendering it through its dynamic block, allowing unauthenticated attackers to execute arbitrary shortcodes on pages that display the feed by planting a shortcode in a review on the connected source.

The vulnerability resides within the Reviews Feed WordPress plugin version 2.6.4 and earlier, where insufficient input sanitization allows for malicious shortcode execution through third-party review content. This flaw represents a classic server-side request forgery vulnerability that enables attackers to inject and execute arbitrary shortcodes without authentication requirements. The issue manifests when the plugin processes review data from external sources and renders it through dynamic blocks without proper neutralization of WordPress shortcode syntax. Attackers can exploit this weakness by submitting malicious shortcodes within review content on connected sources, which then get executed on pages displaying the feed. This vulnerability directly impacts the principle of least privilege as it allows unauthenticated users to execute arbitrary code on the target system through legitimate plugin functionality.
The technical implementation involves the plugin's failure to sanitize user-provided content before rendering it within dynamic blocks. WordPress shortcodes are processed by the wp.shortcode parser which executes registered shortcode handlers when encountering shortcode syntax patterns. The vulnerability occurs because the plugin does not implement proper content sanitization or escaping mechanisms for review data that may contain shortcode delimiters. This flaw can be categorized under CWE-79 as Cross-Site Scripting, specifically in the context of WordPress shortcode execution, and also aligns with CWE-20 as Improper Input Validation. The attack vector operates through the plugin's dynamic rendering mechanism where third-party content is directly processed without proper security checks, allowing attackers to leverage legitimate plugin functionality for malicious purposes.
The operational impact of this vulnerability extends beyond simple code execution, potentially enabling full system compromise through privilege escalation or data exfiltration attacks. An attacker could inject shortcodes that perform actions such as retrieving sensitive information, modifying user permissions, or redirecting traffic to malicious domains. The vulnerability affects any WordPress installation using the affected plugin version and displays a feed on public-facing pages, making it particularly dangerous in environments where third-party reviews are commonly accepted. This weakness can be leveraged through various attack techniques including those listed in the ATT&CK framework under T1190 for Exploit Public-Facing Application and T1059 for Command and Scripting Interpreter. The attack chain typically involves initial compromise through content injection followed by execution of malicious shortcodes that can trigger further exploitation.
Mitigation strategies should focus on immediate plugin updates to version 2.6.5 or later, which contain proper input sanitization measures. Organizations should also implement additional security controls such as content filtering at the network level and monitoring for unusual shortcode patterns in review content. The implementation of proper output escaping for all dynamic content and validation of third-party inputs represents a fundamental security practice that aligns with OWASP Top Ten recommendations for preventing injection attacks. Regular security audits of WordPress plugins and adherence to security best practices including principle of least privilege for plugin functionality should be enforced. Additionally, implementing web application firewalls and monitoring systems can provide additional layers of protection against exploitation attempts through this vulnerability channel.
