CVE-2025-58632 is a stored Cross-site Scripting (XSS) vulnerability classified under CWE-79, affecting the Dadevarzan WordPress Common plugin up to version 2.2.2. This vulnerability arises from improper neutralization of input during web page generation, allowing malicious actors to inject and store arbitrary scripts within the plugin's data handling processes. When a victim accesses a compromised page or interface, the malicious script executes in their browser context, potentially leading to session hijacking, credential theft, unauthorized actions on behalf of the user, or the spread of malware. The CVSS 3.1 base score of 6.5 indicates a medium severity level, reflecting that the vulnerability can be exploited remotely over the network (AV:N), requires low attack complexity (AC:L), but does require privileges (PR:L) and user interaction (UI:R). The scope is changed (S:C), meaning the vulnerability affects resources beyond the initially vulnerable component. The impact affects confidentiality, integrity, and availability to a limited extent (C:L/I:L/A:L). No known exploits are currently reported in the wild, and no patches have been published at the time of this report. The vulnerability is particularly concerning in WordPress environments where the Dadevarzan plugin is installed, as stored XSS can persistently affect multiple users and administrators, potentially compromising entire websites or networks.

For European organizations, the impact of this vulnerability can be significant, especially for those relying on WordPress sites with the Dadevarzan plugin installed. Stored XSS can lead to unauthorized access to sensitive information, including user credentials and session tokens, which may result in data breaches violating GDPR requirements. The integrity of web content and user trust can be compromised, damaging brand reputation and customer confidence. Additionally, attackers could leverage this vulnerability to pivot into internal networks or deploy further malware, affecting operational availability. Organizations in sectors such as finance, healthcare, e-commerce, and government are particularly at risk due to the sensitive nature of their data and regulatory scrutiny. The requirement for user interaction and privileges for exploitation somewhat limits the attack surface but does not eliminate risk, especially in environments with multiple users or lower privilege separation.

European organizations should immediately audit their WordPress installations to identify the presence of the Dadevarzan WordPress Common plugin and its version. Until an official patch is released, organizations should consider disabling or removing the plugin if it is not critical. Implement strict input validation and output encoding on all user-supplied data within the plugin’s context to prevent script injection. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts. Enhance user privilege management to minimize the number of users with elevated permissions (PR:L). Conduct regular security awareness training to reduce the risk of successful social engineering that could trigger user interaction (UI:R). Monitor web application logs for unusual activity indicative of XSS exploitation attempts. Finally, stay updated with vendor advisories and apply patches promptly once available.
