Advices for parsing OCLs

Summary In this postmortem, we analyze the risks of exposing OCL (Object Constraint Language) expressions directly to a web API, as suggested in the query. The core issue is that unvalidated OCL can lead to security vulnerabilities like unauthorized data access and performance issues such as denial-of-service (DoS) via expensive queries. MDriven does provide hooks … Read more

Suspicious opened port on Android 15

Summary An open TCP port (6100, 6300, or 6600) appears on a Samsung Galaxy S21 running Android 15/One UI 7.0.
