CVE-2025-0506 is a medium-severity vulnerability identified in the Rise Blocks – A Complete Gutenberg Page Builder plugin for WordPress. This vulnerability allows for Stored Cross-Site Scripting (XSS) via the titleTag parameter, affecting all versions up to and including 3.6. The root cause of this issue stems from insufficient input sanitization and output escaping, making it a significant concern for WordPress site administrators.
The vulnerability is classified as medium severity due to its CVSS score of 6.4. This score indicates potential risks for organizations using the plugin, particularly those with Contributor-level users who could exploit this flaw to inject arbitrary scripts. Such scripts may execute whenever a user accesses an affected page, leading to unauthorized actions and data exposure.
Given the nature of the vulnerability and the potential impact on web applications, organizations should prioritize patching the Rise Blocks plugin immediately. Failure to address this vulnerability exposes users to various risks, including data theft and compromised user sessions.
Currently, there are no known exploits publicly available for this vulnerability, but organizations should remain vigilant and update their systems as soon as patches are released.
Vulnerability Details
The Rise Blocks plugin is utilized to create and manage content within WordPress sites. The vulnerability identified in CVE-2025-0506 allows for Stored Cross-Site Scripting due to inadequate sanitization of user inputs in the titleTag parameter. Authenticated attackers with Contributor access can exploit this vulnerability to inject malicious scripts into pages. The CVSS score of 6.4 signifies a medium severity level, which indicates that while the exploit may require some user interaction, the impact can still be significant.
The vulnerability was first published on February 12, 2025. It falls under the Common Weakness Enumeration category CWE-79, which denotes improper neutralization of input during web page generation. This classification highlights the necessity for proper coding practices to prevent such vulnerabilities.
Technical Analysis
The root cause of the vulnerability lies in the lack of sufficient input sanitization and output escaping in the Rise Blocks plugin. Attackers can leverage this weakness via the titleTag parameter, which is designed to handle user-generated content. The attack vector is classified as network-based, which means the vulnerability can be exploited remotely over the internet.
The attack complexity is low, requiring minimal technical effort to exploit the vulnerability. Additionally, the privileges required to execute the attack are low, as authenticated users with Contributor-level access can perform the exploitation without needing additional permissions. User interaction is not necessary for the attack, making it easier for attackers to execute malicious scripts.
The impact of this vulnerability affects both confidentiality and integrity, with potential data exposure and unauthorized actions being executed without the user’s consent. However, it does not impact the availability of the application.
Risk & Impact Analysis
Risk to organizations includes unauthorized access to sensitive information and potential manipulation of user sessions due to the injection of malicious scripts. The vulnerability can have a wide blast radius, affecting all users interacting with the compromised pages. Given the low exploitability score and the specific user requirements to exploit this vulnerability, the urgency for remediation is classified as medium.
Organizations should assess their risk management strategies and ensure that they are prepared to apply patches promptly. This could prevent exploitation, especially considering that the attack vector is network-based, making it accessible for remote attackers.
Urgency for defenders is high, as failing to patch the vulnerability may result in compromised web applications, leading to reputational damage and loss of user trust.
