CriticalCVSS 9.1Exploitation Probability (EPSS)
Low risk21th percentile — higher than 21% of all known CVEs
Summary
Capgo before version 12.128.2 contains a vulnerability in its API key generation mechanism that allows for broken authentication. API keys are exposed in frontend requests, and the backend fails to validate that keys are securely generated and bound to the authenticated user.
Risk Assessment
An attacker can tamper with the API key parameter in the generation request, leading to the ability to create custom API keys without proper authorization. This can result in unauthorized access to protected endpoints.
Recommendation
It is recommended to upgrade to version 12.128.2 or later to fix the authentication vulnerability. Additionally, implement API key validation mechanisms to ensure their security.
Original NVD description (English source)
Capgo before 12.128.2 contains a broken authentication vulnerability in its API key generation mechanism. API keys are exposed in frontend requests, and the backend fails to validate that keys are securely generated and bound to the authenticated user. An attacker can tamper with the API key parameter in the generation request and supply arbitrary values, generating custom API keys without proper authorization, which can lead to unauthorized access to protected endpoints.
