CVE-2025-63032 is a stored Cross-site Scripting (XSS) vulnerability classified under CWE-79 affecting the ThinkUpThemes Consulting product up to version 1.5.0. The vulnerability stems from improper neutralization of user-supplied input during web page generation, allowing attackers to inject malicious scripts that are stored on the server and executed in the context of other users' browsers. This type of vulnerability typically enables attackers to steal session cookies, perform actions on behalf of authenticated users, or deface web content. The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L) indicates that the attack is network exploitable with low attack complexity, requires low privileges, and user interaction is necessary. The scope is changed, meaning the vulnerability affects resources beyond the initially vulnerable component. Although no public exploits are known, the persistent nature of stored XSS makes it a significant threat if weaponized. The vulnerability affects web applications using the Consulting theme by ThinkUpThemes, which is commonly deployed in consulting and business service websites. The lack of available patches at the time of publication increases the urgency for mitigation through alternative controls. This vulnerability highlights the importance of proper input validation, output encoding, and security headers to prevent script injection and execution.

For European organizations, this vulnerability poses a risk to the confidentiality, integrity, and availability of web applications using the ThinkUpThemes Consulting product. Attackers exploiting this stored XSS could hijack user sessions, steal sensitive information, or manipulate website content, potentially damaging brand reputation and customer trust. Given the consulting sector's reliance on client data and communications, such breaches could lead to regulatory non-compliance under GDPR, resulting in fines and legal consequences. The requirement for low privileges and user interaction lowers the barrier for exploitation, increasing risk especially in environments with many users or clients accessing the affected web portals. Persistent XSS can also serve as a foothold for further attacks, including phishing or malware distribution. The impact is amplified in countries with high digital service adoption and stringent data protection laws, where breaches have both operational and financial repercussions.

Organizations should immediately inventory their web assets to identify deployments of ThinkUpThemes Consulting up to version 1.5.0. Until official patches are released, implement strict input validation and output encoding on all user-supplied data to prevent script injection. Deploy Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts. Regularly audit and sanitize stored content to remove any malicious payloads. Limit user privileges to the minimum necessary to reduce exploitation potential. Educate users about the risks of interacting with suspicious content to mitigate social engineering vectors. Monitor web application logs for unusual activities indicative of XSS exploitation attempts. Once patches become available, prioritize their application in all affected environments. Additionally, consider deploying Web Application Firewalls (WAFs) configured to detect and block XSS payloads targeting this vulnerability.
