CVE-2025-58832 is a medium-severity Stored Cross-Site Scripting (XSS) vulnerability classified under CWE-79, affecting the 'Search by Google' product developed by webvitaly. The vulnerability arises from improper neutralization of input during web page generation, allowing malicious actors to inject and store malicious scripts within the application. When a victim accesses the affected page, the stored script executes in their browser context. This vulnerability affects all versions up to 1.9, with no specific version exclusions noted. The CVSS 3.1 base score is 5.9, reflecting a network attack vector (AV:N), low attack complexity (AC:L), but requiring high privileges (PR:H) and user interaction (UI:R). The scope is changed (S:C), indicating that the vulnerability affects resources beyond the security scope of the vulnerable component. The impact includes low confidentiality, integrity, and availability impacts, but the stored nature of the XSS can facilitate persistent attacks such as session hijacking, credential theft, or defacement. No known exploits are reported in the wild, and no patches are currently linked. The vulnerability was published on September 5, 2025, and assigned by Patchstack. Stored XSS vulnerabilities are particularly dangerous because they can affect multiple users and persist until remediated. The requirement for high privileges and user interaction somewhat limits exploitation but does not eliminate risk, especially in environments where privileged users interact with the vulnerable component frequently.

For European organizations, this vulnerability poses a risk primarily to web applications or services utilizing the 'Search by Google' plugin or product by webvitaly. If integrated into customer-facing or internal portals, attackers could exploit the stored XSS to execute malicious scripts in the browsers of users with elevated privileges, potentially leading to session hijacking, unauthorized actions, or data leakage. Given the scope change, the vulnerability could allow attackers to affect resources beyond the immediate application, increasing the risk of lateral movement or privilege escalation within organizational networks. This can impact confidentiality by exposing sensitive information, integrity by enabling unauthorized data manipulation, and availability by potentially disrupting services through script-based attacks. European organizations with strict data protection regulations such as GDPR must be cautious, as exploitation could lead to data breaches and regulatory penalties. The requirement for high privileges and user interaction reduces the likelihood of widespread automated exploitation but does not eliminate targeted attacks against administrators or privileged users. The absence of known exploits in the wild suggests the threat is currently theoretical but should be addressed proactively to prevent future exploitation.

1. Immediate mitigation should include input validation and output encoding to ensure that all user-supplied data is properly sanitized before rendering in web pages, specifically targeting the 'Search by Google' component. 2. Implement Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of potential XSS payloads. 3. Restrict access to the vulnerable component to only necessary privileged users and monitor their activities for suspicious behavior. 4. Conduct regular security audits and penetration testing focusing on web application components that integrate third-party plugins like 'Search by Google'. 5. Since no patches are currently linked, organizations should engage with the vendor webvitaly for updates or consider disabling or replacing the vulnerable component until a fix is available. 6. Educate privileged users about the risks of interacting with untrusted content and the importance of cautious behavior to reduce the risk of social engineering that could trigger user interaction requirements. 7. Employ web application firewalls (WAFs) configured to detect and block common XSS attack patterns targeting this component. 8. Monitor logs and alerts for any signs of attempted exploitation or anomalous script execution related to the vulnerable product.
