CVE-2025-6462 is a stored Cross-Site Scripting (XSS) vulnerability identified in the scheeeli EZ SQL Reports Shortcode Widget and DB Backup plugin for WordPress, affecting all versions up to and including 5.25.11. The vulnerability stems from improper neutralization of input during web page generation, specifically within the SQLREPORT shortcode functionality. The plugin fails to adequately sanitize and escape user-supplied attributes, allowing authenticated users with contributor-level permissions or higher to inject arbitrary JavaScript code into pages. When other users access these pages, the injected scripts execute in their browsers, potentially leading to session hijacking, privilege escalation, or unauthorized actions performed on behalf of the victim. The vulnerability requires no user interaction beyond visiting the compromised page and can be exploited remotely over the network. The CVSS v3.1 score of 6.4 reflects a medium severity, with attack vector as network, low attack complexity, privileges required, no user interaction, and a scope change indicating that the vulnerability affects resources beyond the initially compromised component. Although no known exploits have been reported in the wild, the vulnerability poses a significant risk to WordPress sites using this plugin, especially those allowing contributor-level access to untrusted users. The lack of available patches at the time of publication necessitates immediate mitigation efforts.

The impact of CVE-2025-6462 is primarily on the confidentiality and integrity of affected WordPress sites. Successful exploitation allows attackers to execute arbitrary JavaScript in the context of the victim’s browser, enabling theft of authentication cookies, session tokens, or other sensitive information. This can lead to account takeover, unauthorized administrative actions, or defacement of the website. Since the vulnerability requires contributor-level access, it is particularly dangerous in environments where multiple users have content publishing permissions, including multi-author blogs or corporate intranets. The scope change in the CVSS vector indicates that the vulnerability can affect components beyond the plugin itself, potentially compromising the entire site. Although availability is not directly impacted, the resulting compromise can lead to service disruption or loss of user trust. Organizations relying on this plugin face risks of reputational damage, data breaches, and regulatory non-compliance if exploited.

To mitigate CVE-2025-6462, organizations should first check for and apply any official patches or updates released by the plugin vendor. If no patch is available, immediate steps include restricting contributor-level access to trusted users only and auditing existing content for injected scripts. Implementing a Web Application Firewall (WAF) with rules to detect and block malicious script payloads in shortcode attributes can provide temporary protection. Site administrators should also enable Content Security Policy (CSP) headers to limit the execution of unauthorized scripts. Regularly scanning the website for XSS payloads and monitoring user activity logs can help identify exploitation attempts. Additionally, educating content contributors about safe input practices and limiting the use of shortcodes to trusted users reduces risk. Finally, consider disabling or replacing the vulnerable plugin with a more secure alternative if feasible.
