CVE-2025-58805 is a medium-severity vulnerability classified under CWE-79, indicating an improper neutralization of input during web page generation, commonly known as a Cross-site Scripting (XSS) flaw. This vulnerability affects the OTWthemes product 'Widgetize Pages Light' up to version 3.0. Specifically, it is a Stored XSS vulnerability, meaning that malicious input submitted by an attacker is persistently stored by the application and later rendered in web pages viewed by other users without proper sanitization or encoding. The vulnerability allows an attacker with at least some level of authenticated access (as indicated by the CVSS vector requiring privileges and user interaction) to inject malicious scripts into the web interface. These scripts can execute in the context of other users' browsers, potentially leading to session hijacking, credential theft, or unauthorized actions performed on behalf of the victim. The CVSS score of 5.9 reflects a moderate risk, with network attack vector, low attack complexity, but requiring privileges and user interaction, and impacting confidentiality, integrity, and availability to a limited extent. The scope is changed, indicating the vulnerability affects components beyond the initially vulnerable module. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability was published recently in September 2025, suggesting that affected organizations should prioritize assessment and remediation. Since Widgetize Pages Light is a WordPress-related theme plugin, it is likely used in content management systems for website customization and widget management, making it a relevant target for attackers seeking to compromise websites and their users through XSS attacks.

For European organizations, this vulnerability poses a risk primarily to websites using the Widgetize Pages Light plugin, which may include corporate, governmental, or e-commerce sites relying on WordPress themes for content presentation. Successful exploitation could lead to session hijacking, defacement, or unauthorized actions performed by attackers impersonating legitimate users. This can result in data leakage, reputational damage, and potential regulatory non-compliance under GDPR if personal data is compromised. The requirement for privileges and user interaction somewhat limits the attack surface but does not eliminate risk, especially in environments with multiple users having varying access levels. Attackers could leverage social engineering to trick privileged users into triggering the malicious payload. The impact on availability is limited but possible if injected scripts disrupt normal site functionality. Given the interconnected nature of European digital infrastructure and the high reliance on web platforms, exploitation could have cascading effects on business operations and user trust.

Organizations should immediately audit their WordPress installations to identify the presence of the Widgetize Pages Light plugin, especially versions up to 3.0. Until an official patch is released, administrators should consider disabling or removing the plugin to eliminate exposure. Implementing strict input validation and output encoding on all user-supplied data fields within the plugin's scope is critical to prevent script injection. Web Application Firewalls (WAFs) can be configured with custom rules to detect and block typical XSS payloads targeting this plugin. Additionally, enforcing the principle of least privilege to limit user roles and permissions reduces the risk of exploitation requiring privileged access. User awareness training to recognize phishing or social engineering attempts that could trigger user interaction is also recommended. Monitoring web logs for unusual script injections or anomalous user behavior can help detect attempted exploitation early. Finally, organizations should stay alert for official patches or updates from OTWthemes and apply them promptly once available.
