CVE-2025-8105 in Soledad Plugin
Summary
by MITRE • 08/16/2025
The The Soledad theme for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 8.6.7. This is due to the software allowing users to execute an action that does not properly validate a value before running do_shortcode. This makes it possible for unauthenticated attackers to execute arbitrary shortcodes.

The CVE-2025-8105 vulnerability affects the Soledad theme for WordPress, representing a critical security flaw that enables unauthenticated attackers to execute arbitrary shortcodes. This vulnerability exists in all versions up to and including 8.6.7, making it a widespread concern for WordPress site administrators who rely on this theme. The flaw stems from inadequate input validation within the theme's shortcode execution mechanism, specifically in how the software handles user-provided values before processing them through the do_shortcode function. This type of vulnerability falls under CWE-20, which describes improper input validation, and represents a significant risk to WordPress installations using the affected theme.
The technical implementation of this vulnerability allows attackers to inject malicious shortcodes through user input fields or parameters that are processed by the theme without proper sanitization. When the do_shortcode function executes without adequate validation, it processes any shortcode present in the input, potentially enabling attackers to execute arbitrary code or perform unauthorized actions within the WordPress environment. This weakness creates a pathway for attackers to leverage the theme's functionality against the target system, potentially leading to complete compromise of the affected WordPress installation. The vulnerability's impact is amplified by the fact that no authentication is required to exploit it, making it particularly dangerous for publicly accessible websites.
The operational consequences of this vulnerability extend beyond simple code execution, as it can enable attackers to perform a wide range of malicious activities including data exfiltration, defacement, or installation of backdoors. Attackers could potentially exploit this flaw to inject malicious content, modify website functionality, or gain unauthorized access to sensitive data stored within the WordPress environment. The vulnerability's presence in all versions up to 8.6.7 means that a substantial number of WordPress installations could be at risk, particularly those that have not updated to newer versions of the theme. This creates a significant attack surface that aligns with tactics described in the MITRE ATT&CK framework under T1190 for exploitation of remote services and T1059 for execution through command and scripting interpreters.
Mitigation strategies for CVE-2025-8105 should prioritize immediate theme updates to versions that address the input validation flaw. WordPress administrators should ensure they are running the latest version of the Soledad theme, which should include proper validation of shortcode parameters before execution. Additionally, implementing input sanitization measures and restricting user input through proper validation routines can help prevent exploitation. Organizations should also consider implementing web application firewalls and monitoring for suspicious shortcode execution patterns. The vulnerability's classification as a remote code execution risk means that administrators should perform immediate security assessments of their WordPress installations and ensure that all theme components are properly updated. Regular security audits and vulnerability scanning should be implemented to identify similar weaknesses in other themes or plugins that might present comparable risks to the WordPress ecosystem.
