CVE-2025-10053 is a stored cross-site scripting (XSS) vulnerability identified in the TableGen – Data Table Generator plugin for WordPress, affecting all versions up to and including 1.3.1. The root cause is improper neutralization of input during web page generation, specifically due to insufficient sanitization and output escaping of administrator-configured settings. This flaw allows authenticated users with administrator or higher privileges to inject arbitrary JavaScript code into pages generated by the plugin. The vulnerability is limited to multi-site WordPress installations or those where the unfiltered_html capability is disabled, restricting the attack surface somewhat. When a user visits a page containing the injected script, the malicious code executes in their browser context, potentially enabling session hijacking, credential theft, or further privilege escalation. The CVSS 3.1 vector indicates network attack vector (remote), high attack complexity, requiring high privileges, no user interaction, and a scope change with low confidentiality and integrity impact but no availability impact. No patches or exploits are currently publicly available, but the vulnerability is published and should be addressed promptly. The vulnerability is cataloged under CWE-79, a common and well-understood XSS weakness. Given the requirement for administrator-level access, exploitation is limited to insiders or compromised admin accounts, but the impact on confidentiality and integrity can be significant in such cases.

The primary impact of CVE-2025-10053 is the potential for attackers with administrator privileges to inject malicious scripts that execute in the context of other users visiting affected pages. This can lead to session hijacking, theft of sensitive data, or execution of unauthorized actions on behalf of users, undermining confidentiality and integrity. Since the vulnerability affects multi-site WordPress installations or those with unfiltered_html disabled, organizations running large WordPress networks or those with strict content filtering are at higher risk. The requirement for high privileges limits exploitation to insiders or attackers who have already compromised admin accounts, reducing the likelihood of external exploitation but increasing the risk of insider threats or privilege escalation chains. The vulnerability does not impact availability directly but can facilitate further attacks that degrade system trustworthiness. Organizations relying on this plugin for data table generation in WordPress environments may face reputational damage, data breaches, or compliance violations if exploited.

To mitigate CVE-2025-10053, organizations should immediately update the TableGen – Data Table Generator plugin to a patched version once available. Until a patch is released, restrict administrator access to trusted personnel only and monitor admin activities closely. Implement strict input validation and output encoding in custom plugin configurations if possible. Consider disabling or limiting multi-site WordPress installations if not required, as the vulnerability specifically affects these setups. Enable web application firewalls (WAFs) with rules to detect and block XSS payloads targeting the plugin’s admin settings. Regularly audit user permissions to ensure no unnecessary administrator accounts exist. Employ Content Security Policy (CSP) headers to reduce the impact of injected scripts. Finally, maintain comprehensive logging and alerting on suspicious admin changes or unusual page content modifications to detect exploitation attempts early.
