⚠️ Risk & Real-World Impact
Worst Case
Attackers gain access to log files containing credentials, API keys, or sensitive data, leading to unauthorized system access and data breaches.
Likely Case
Internal users or administrators inadvertently expose sensitive information through log files, potentially violating compliance requirements.
If Mitigated
With proper log file permissions and monitoring, the exposed information remains inaccessible to unauthorized users.
🎯 Exploit Status
Exploitation requires access to log files, which typically needs some level of system access or misconfigured permissions.
