CVE-2025-61119 identifies an improper access control vulnerability in the Kanova Android application version 1.0.27, developed by Karely L.L.C. The vulnerability arises from insufficient validation of API request parameters, allowing attackers to manipulate these parameters to access unauthorized user details and group information, including entry codes that control group access. This flaw compromises the confidentiality and integrity of user data and group security mechanisms within the app. The vulnerability does not require user interaction but depends on the attacker’s ability to send crafted API requests, potentially through intercepted or forged network traffic. Although no known exploits are currently reported in the wild, the risk remains significant due to the sensitive nature of the exposed information. The lack of a CVSS score indicates that the vulnerability is newly published and awaiting further evaluation. The app’s improper access control could be exploited to breach privacy, gain unauthorized entry to groups, and misuse platform functionalities, potentially impacting organizational security where the app is used for group management or access control. The vulnerability highlights the importance of robust API security, including strict parameter validation and authentication enforcement.

For European organizations, this vulnerability poses a significant risk to privacy and security, especially for those using the Kanova app for group management or access control. Unauthorized access to user details and group entry codes could lead to data breaches, unauthorized physical or logical access to restricted groups, and potential misuse of organizational resources. The exposure of entry codes could facilitate unauthorized physical access if these codes control physical entry points, increasing the risk of theft, espionage, or sabotage. Privacy breaches could also result in regulatory non-compliance under GDPR, leading to legal and financial consequences. The impact is heightened in sectors with sensitive data or critical infrastructure, such as finance, healthcare, and government. The absence of known exploits provides a window for proactive mitigation, but the vulnerability’s nature demands urgent attention to prevent exploitation. The potential for widespread impact depends on the app’s adoption rate within European organizations and the sensitivity of the groups managed through the platform.

To mitigate CVE-2025-61119, organizations should prioritize updating the Kanova Android app once a patch is released by Karely L.L.C. In the interim, restrict app usage to trusted networks and monitor API traffic for unusual or unauthorized requests that could indicate exploitation attempts. Implement network-level controls such as API gateways or web application firewalls (WAFs) to enforce strict validation of API parameters and block malformed or unauthorized requests. Conduct thorough access reviews of groups managed via the app to identify and revoke unnecessary permissions or entry codes. Educate users about the risks of using outdated app versions and encourage prompt updates. For organizations managing physical access via the app, consider additional authentication layers or alternative access control methods until the vulnerability is resolved. Regularly audit logs for suspicious activity related to group access and user detail retrieval. Engage with Karely L.L.C. to obtain timelines for patches and request security advisories. Finally, incorporate this vulnerability into incident response plans to ensure rapid containment if exploitation is detected.
