CVE-2025-58022 is a security vulnerability classified as CWE-79, which pertains to Improper Neutralization of Input During Web Page Generation, commonly known as Cross-site Scripting (XSS). Specifically, this vulnerability affects the maxpagels ShortCode product, versions up to 0.8.1. The flaw allows an attacker to inject malicious scripts that are stored and later executed in the context of users visiting the affected web pages. This type of Stored XSS can lead to unauthorized actions performed on behalf of the victim, theft of session cookies, or other sensitive information disclosure. The vulnerability is exploitable remotely (AV:N), requires low attack complexity (AC:L), but does require privileges (PR:L) and user interaction (UI:R) to trigger. The scope is changed (S:C), indicating that the vulnerability affects resources beyond the security scope of the vulnerable component. The impact affects confidentiality, integrity, and availability to a limited but non-negligible extent, reflected in the CVSS score of 6.5 (medium severity). No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability was reserved in August 2025 and published in September 2025, indicating it is a recent discovery. The maxpagels ShortCode is likely a plugin or module used in web content management or development environments, where user input is embedded in web pages without proper sanitization or encoding, leading to this Stored XSS risk.

For European organizations, the impact of CVE-2025-58022 can be significant, especially for those relying on maxpagels ShortCode in their web infrastructure. Stored XSS vulnerabilities can lead to session hijacking, defacement, phishing, and unauthorized actions performed under the victim’s credentials. This can compromise user trust, lead to data breaches involving personal data protected under GDPR, and cause reputational damage. Additionally, the scope change means that the vulnerability could allow attackers to affect other components or users beyond the initially vulnerable system, potentially leading to broader compromise. Organizations in sectors such as e-commerce, finance, healthcare, and government, which often handle sensitive personal or financial data, are particularly at risk. The requirement for some privileges and user interaction reduces the ease of exploitation but does not eliminate the threat, as attackers may leverage social engineering or compromised accounts to trigger the exploit. The absence of known exploits in the wild provides a window for proactive mitigation before widespread attacks occur.

To mitigate CVE-2025-58022, European organizations should: 1) Immediately audit their use of maxpagels ShortCode and identify all instances and versions deployed. 2) Apply any available patches or updates from the vendor as soon as they are released. In the absence of official patches, implement input validation and output encoding measures to neutralize potentially malicious input, especially for user-generated content embedded via ShortCode. 3) Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in web browsers. 4) Conduct thorough security testing, including automated and manual penetration testing focusing on XSS vectors in affected web pages. 5) Educate users and administrators about the risks of phishing and social engineering that could facilitate exploitation requiring user interaction. 6) Monitor web application logs and user activity for suspicious behavior indicative of exploitation attempts. 7) Consider deploying Web Application Firewalls (WAFs) with rules tailored to detect and block XSS payloads targeting the ShortCode component. These steps go beyond generic advice by focusing on the specific product and vulnerability characteristics.
