CVE-2025-11029 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the givanz Vvveb product versions up to 1.0.7.2. CSRF vulnerabilities allow attackers to trick authenticated users into submitting unwanted actions on a web application in which they are currently authenticated, without their consent or knowledge. This particular vulnerability affects unknown code components within Vvveb, a web-based tool or framework developed by givanz. The attack can be executed remotely and does not require any privileges or authentication, but it does require user interaction (e.g., clicking a malicious link or visiting a crafted webpage). The CVSS 4.0 base score of 5.3 reflects a medium severity level, indicating a moderate impact primarily on the integrity of the affected system, with no direct impact on confidentiality or availability. The vulnerability has been publicly disclosed, and while an exploit is available, there are no known exploits actively used in the wild at this time. The project maintainer has acknowledged the issue and committed to releasing a fixed version on GitHub, demonstrating a responsible disclosure and remediation process. The vulnerability’s exploitation could allow attackers to perform unauthorized state-changing operations on behalf of legitimate users, potentially leading to unauthorized modifications or actions within applications using Vvveb. However, the lack of privilege requirements and the need for user interaction somewhat limit the attack scope and impact.

For European organizations using givanz Vvveb, this vulnerability poses a moderate risk. If Vvveb is integrated into internal or customer-facing web applications, attackers could exploit the CSRF flaw to perform unauthorized actions, potentially leading to data integrity issues or unauthorized changes in application state. This could affect business processes, user trust, and compliance with data protection regulations such as GDPR if personal data is indirectly impacted. The remote exploitability and lack of required privileges mean that attackers can target a broad range of users, increasing the risk of successful attacks. However, since the vulnerability requires user interaction and does not affect confidentiality or availability directly, the overall impact is contained but still significant enough to warrant prompt remediation. Organizations relying on Vvveb for web content editing or similar functions should prioritize patching to prevent potential misuse that could disrupt workflows or compromise application integrity.

European organizations should immediately upgrade to the fixed version of givanz Vvveb once it is released on GitHub, as indicated by the maintainer. Until the patch is applied, organizations can implement several practical mitigations: 1) Employ anti-CSRF tokens in all state-changing requests within applications using Vvveb to ensure requests are legitimate. 2) Enforce strict SameSite cookie attributes (e.g., SameSite=Lax or Strict) to reduce the risk of CSRF attacks via cross-site requests. 3) Educate users about the risks of clicking unknown or suspicious links, especially when authenticated to sensitive applications. 4) Monitor web application logs for unusual or unexpected state-changing requests that could indicate attempted exploitation. 5) Use Content Security Policy (CSP) headers to restrict the sources of executable scripts and reduce the attack surface. 6) If feasible, implement multi-factor authentication (MFA) to add an additional layer of security, although it does not directly prevent CSRF, it can limit the impact of compromised sessions. These measures, combined with timely patching, will significantly reduce the risk posed by this vulnerability.
