CVE-2026-22469 identifies a Cross-Site Scripting (XSS) vulnerability in the mwtemplates DeepDigital product, specifically in versions up to and including 1.0.2. The root cause is improper neutralization of script-related HTML tags within web pages generated or managed by DeepDigital, which allows attackers to inject arbitrary code. This vulnerability is classified as a basic XSS flaw, meaning that malicious scripts can be embedded into web content and executed in the browsers of users who visit the affected pages. The CVSS score of 5.3 (medium severity) reflects that the attack vector is network-based (remote), requires no privileges or user interaction, and impacts integrity but not confidentiality or availability. Exploitation could allow attackers to modify the displayed content, perform actions on behalf of users, or conduct phishing attacks by injecting deceptive scripts. Although no public exploits have been reported, the vulnerability poses a risk to web applications using DeepDigital, especially those exposed to the internet. The lack of available patches at the time of publication necessitates immediate attention to alternative mitigations. The vulnerability's presence in a web template product suggests that multiple websites or services could be affected if they utilize the vulnerable versions of DeepDigital.

For European organizations, this vulnerability can undermine the integrity of web applications relying on DeepDigital, potentially leading to unauthorized script execution in users' browsers. This can facilitate phishing, session hijacking, or defacement attacks, damaging organizational reputation and user trust. While confidentiality and availability are not directly impacted, the integrity compromise can indirectly lead to data exposure or service misuse. Organizations in sectors with high web presence such as e-commerce, government services, and media are particularly vulnerable. The risk is amplified for entities with large user bases or those handling sensitive user interactions through affected web pages. Additionally, regulatory frameworks like GDPR emphasize protecting user data and privacy, so exploitation leading to user data compromise could result in compliance violations and penalties. The absence of known exploits currently reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits over time.

European organizations should immediately inventory their use of mwtemplates DeepDigital to identify affected versions (<= 1.0.2). In the absence of official patches, implement strict input validation and output encoding to neutralize script tags and other potentially malicious inputs. Deploy Content Security Policies (CSP) to restrict the execution of unauthorized scripts on affected web pages. Utilize web application firewalls (WAFs) with rules targeting XSS attack patterns to provide an additional layer of defense. Conduct thorough code reviews and penetration testing focusing on injection points within DeepDigital-managed content. Educate developers and administrators on secure coding practices to prevent similar vulnerabilities. Monitor web traffic and logs for signs of attempted exploitation. Plan for timely updates once patches become available from the vendor. Finally, ensure incident response plans include procedures for handling XSS incidents to minimize impact.
