CVE-2025-11026 is a medium severity information disclosure vulnerability affecting the givanz Vvveb product versions 1.0.7.0 through 1.0.7.2. The vulnerability resides in an unspecified functionality of the Configuration File Handler component. This flaw allows an attacker to remotely manipulate the component to disclose sensitive information. The vulnerability can be exploited over the network without requiring authentication, though it does require some user interaction. The CVSS 4.0 vector indicates the attack complexity is low, no privileges are required, but user interaction is necessary. The impact is limited to confidentiality with no effect on integrity or availability. The project maintainer has acknowledged the vulnerability and committed to releasing a patched version on GitHub, demonstrating a responsible disclosure and remediation approach. No known exploits are currently active in the wild, but the exploit code has been publicly disclosed, increasing the risk of exploitation. The exact nature of the information disclosed is not detailed, but given the involvement of a configuration file handler, it could potentially expose configuration data, credentials, or other sensitive operational parameters. The vulnerability’s remote attack vector and low complexity make it a concern for organizations using affected versions of Vvveb, especially if the software is exposed to untrusted networks or the internet.

For European organizations, the information disclosure vulnerability in givanz Vvveb could lead to leakage of sensitive configuration data, which might include credentials, API keys, or internal system details. This could facilitate further attacks such as privilege escalation, lateral movement, or targeted exploitation of other systems. Organizations using Vvveb in web development or content management may face risks to confidentiality, potentially impacting customer data privacy and compliance with regulations such as GDPR. While the vulnerability does not directly affect system integrity or availability, the indirect consequences of leaked information could be significant, especially in sectors handling sensitive or regulated data. The requirement for user interaction slightly reduces the risk but does not eliminate it, particularly in environments where social engineering or phishing could be leveraged. The public disclosure of exploit code increases the urgency for European entities to apply patches or mitigations promptly to prevent exploitation.

European organizations should immediately identify all instances of givanz Vvveb versions 1.0.7.0 through 1.0.7.2 in their environments. They should prioritize upgrading to the fixed version once released by the maintainer on GitHub. Until patches are applied, organizations should restrict network access to the affected component, ideally limiting it to trusted internal networks and blocking external access via firewalls or network segmentation. Implementing strict input validation and monitoring for unusual access patterns to the Configuration File Handler component can help detect exploitation attempts. User awareness training to reduce the risk of social engineering that could trigger the required user interaction is also recommended. Additionally, organizations should audit configuration files and credentials potentially exposed by this vulnerability and rotate any sensitive keys or passwords as a precaution. Employing web application firewalls (WAFs) with custom rules to detect and block suspicious requests targeting the vulnerable functionality can provide an additional layer of defense.
