CVE-2025-47482 is a vulnerability classified as CWE-79, indicating an improper neutralization of input during web page generation, commonly known as Cross-site Scripting (XSS). This specific vulnerability affects the SKT Skill Bar plugin developed by sonalsinha21, up to version 2.4. The flaw allows an attacker to inject malicious scripts that are stored persistently within the application, leading to Stored XSS. When a victim accesses a page containing the malicious payload, the script executes in their browser context. This can lead to a range of malicious activities including session hijacking, defacement, redirection to malicious sites, or the execution of arbitrary actions on behalf of the user. The CVSS 3.1 base score of 6.5 reflects a medium severity level, with an attack vector of network (remote exploitation), low attack complexity, requiring privileges (PR:L) and user interaction (UI:R). The scope is changed (S:C), indicating that the vulnerability affects resources beyond the initially vulnerable component. The impact on confidentiality, integrity, and availability is low to medium, as the attacker can partially compromise user data and potentially disrupt service. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability was published on May 7, 2025, and is recognized by CISA, indicating its relevance to cybersecurity stakeholders. The absence of a patch suggests that users of the SKT Skill Bar plugin should consider mitigation strategies promptly to reduce risk.

For European organizations, the impact of this Stored XSS vulnerability can be significant, especially for those relying on the SKT Skill Bar plugin in their web infrastructure. Exploitation could lead to unauthorized access to user sessions, theft of sensitive information, and potential defacement or manipulation of web content. This can damage organizational reputation, lead to regulatory non-compliance under GDPR due to data breaches, and disrupt business operations. Since the vulnerability requires user interaction, phishing or social engineering campaigns could be used to lure users into triggering the exploit. The changed scope means that the attack could affect other components or users beyond the initial vulnerable plugin, potentially amplifying the damage. Organizations in sectors such as finance, healthcare, and e-commerce, which handle sensitive personal data, are particularly at risk. Additionally, the medium severity score indicates that while the vulnerability is not critical, it still poses a tangible threat that should be addressed promptly to avoid exploitation.

Given the absence of an official patch, European organizations should implement immediate compensating controls. These include: 1) Applying strict input validation and output encoding on all user-supplied data related to the SKT Skill Bar plugin to prevent script injection. 2) Employing Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. 3) Conducting thorough code reviews and sanitization routines within the plugin's integration points. 4) Limiting user privileges to reduce the impact of potential exploitation, as the vulnerability requires some level of privilege. 5) Educating users about phishing risks and suspicious links to minimize user interaction exploitation. 6) Monitoring web application logs for unusual activity or script injection attempts. 7) Considering temporary removal or disabling of the SKT Skill Bar plugin until a patch is available. 8) Keeping all web platform components and dependencies up to date to reduce the attack surface. These measures collectively reduce the risk of exploitation and limit potential damage.
