CVE-2025-46875 is a reflected Cross-Site Scripting (XSS) vulnerability affecting Adobe Experience Manager (AEM) versions 6.5.22 and earlier. This vulnerability arises when an attacker crafts a malicious URL referencing a vulnerable page within AEM, which, when visited by a victim, causes the execution of attacker-controlled JavaScript code in the context of the victim's browser. The vulnerability requires the attacker to have low privileges and to convince the victim to click or visit the malicious URL, implying user interaction is necessary. The reflected nature of the XSS means the malicious script is not stored persistently on the server but reflected off a web request, making it a transient attack vector. The CVSS 3.1 base score is 5.4 (medium severity), with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), low privileges required (PR:L), user interaction required (UI:R), scope changed (S:C), and impacts on confidentiality and integrity (C:L/I:L) but no impact on availability (A:N). The vulnerability could allow attackers to steal session cookies, perform actions on behalf of the victim, or manipulate the victim's view of the web application, potentially leading to further attacks such as privilege escalation or data leakage. No known exploits are currently reported in the wild, and no patches or mitigation links are provided yet, indicating the vulnerability is newly disclosed and may require urgent attention from organizations using affected versions of AEM.

For European organizations using Adobe Experience Manager, this vulnerability poses a moderate risk to the confidentiality and integrity of their web applications and user data. Given AEM's widespread use in enterprise content management and digital experience delivery, exploitation could lead to unauthorized access to sensitive information, session hijacking, or manipulation of web content, undermining trust and compliance with data protection regulations such as GDPR. The requirement for user interaction means phishing or social engineering campaigns could be used to exploit this vulnerability, targeting employees or customers. This could result in reputational damage, regulatory penalties, and operational disruptions. Organizations in sectors with high reliance on digital customer engagement platforms, such as finance, government, healthcare, and retail, are particularly at risk. The reflected XSS could also serve as an initial foothold for more complex attacks, including lateral movement or deployment of malware within corporate networks.

European organizations should prioritize upgrading Adobe Experience Manager to the latest version once a patch is released by Adobe. In the interim, organizations can implement strict input validation and output encoding on all user-supplied data to prevent script injection. Web Application Firewalls (WAFs) should be configured to detect and block common XSS attack patterns targeting AEM endpoints. Security teams should conduct phishing awareness training to reduce the likelihood of users clicking malicious links. Additionally, Content Security Policy (CSP) headers can be deployed to restrict the execution of unauthorized scripts in browsers. Regular security assessments and penetration testing focused on web application vulnerabilities should be conducted to identify and remediate similar issues proactively. Monitoring web traffic for unusual patterns and implementing multi-factor authentication can further reduce the impact of potential session hijacking.
