CVE-2025-13082 is a vulnerability classified under CWE-451, indicating a User Interface (UI) misrepresentation of critical information within Drupal core. This flaw allows attackers to perform content spoofing by manipulating how information is displayed to end users, potentially misleading them about the authenticity or source of displayed content. The affected versions span from Drupal 8.0.0 up to versions prior to 10.4.9, 10.5.6, 11.1.9, and 11.2.8, covering a broad range of Drupal core releases. The vulnerability has a CVSS v3.1 base score of 4.3, reflecting a medium severity level. The vector indicates that the attack can be performed remotely (AV:N) with low attack complexity (AC:L), requires no privileges (PR:N), but does require user interaction (UI:R). The scope is unchanged (S:U), and the impact is limited to availability (A:L) with no confidentiality or integrity impact. This suggests that while the attacker cannot steal or alter data, they can cause minor disruptions or mislead users through UI content spoofing. No known exploits have been reported in the wild, but the potential for social engineering or phishing attacks leveraging this vulnerability exists. The absence of patch links in the provided data suggests that updates addressing this issue are available in Drupal core versions 10.4.9, 10.5.6, 11.1.9, and 11.2.8 and later, and organizations should upgrade accordingly. The vulnerability may be exploited by crafting specially designed content or URLs that cause the Drupal UI to display misleading information, potentially tricking users into performing unintended actions or disclosing sensitive information.

For European organizations, this vulnerability primarily poses a risk to the integrity of user interactions with web applications powered by Drupal core. While it does not compromise data confidentiality or integrity directly, the UI misrepresentation can facilitate phishing, social engineering, or fraudulent activities by deceiving users about the authenticity of displayed content. This can lead to reputational damage, loss of user trust, and potential indirect financial losses if users are tricked into submitting sensitive information or credentials. Public sector websites, e-commerce platforms, and any Drupal-based portals handling user interactions are particularly vulnerable to exploitation. The availability impact is low but may cause minor service disruptions or user confusion. Since Drupal is widely used across Europe for government, education, and commercial websites, the scope of affected systems is significant. The requirement for user interaction means that attackers must entice users to engage with malicious content, which may limit large-scale automated exploitation but does not eliminate targeted attacks. Organizations failing to patch may face increased risk of targeted phishing campaigns leveraging this vulnerability.

European organizations should immediately assess their Drupal core versions and upgrade to the fixed releases: 10.4.9 or later, 10.5.6 or later, 11.1.9 or later, and 11.2.8 or later. Beyond upgrading, organizations should audit custom themes and modules for any UI rendering logic that could exacerbate spoofing risks and implement strict input validation and output encoding to prevent injection of misleading content. Employing Content Security Policy (CSP) headers can help mitigate the impact of injected scripts or content manipulation. User education campaigns should be conducted to raise awareness about phishing and spoofing risks, emphasizing caution when interacting with unexpected or suspicious UI elements. Web application firewalls (WAFs) can be tuned to detect and block suspicious payloads targeting Drupal UI components. Regular monitoring of web logs and user reports for anomalies related to UI content can help detect exploitation attempts early. Finally, organizations should subscribe to Drupal security advisories to promptly receive updates on patches and related vulnerabilities.
