From b55d9fa68d27848d9e0367447142771dd0c0fc7b Mon Sep 17 00:00:00 2001 From: master <> Date: Tue, 16 Dec 2025 13:11:57 +0200 Subject: [PATCH] Add comprehensive security tests for OWASP A03 (Injection) and A10 (SSRF) - Implemented InjectionTests.cs to cover various injection vulnerabilities including SQL, NoSQL, Command, LDAP, and XPath injections. - Created SsrfTests.cs to test for Server-Side Request Forgery (SSRF) vulnerabilities, including internal URL access, cloud metadata access, and URL allowlist bypass attempts. - Introduced MaliciousPayloads.cs to store a collection of malicious payloads for testing various security vulnerabilities. - Added SecurityAssertions.cs for common security-specific assertion helpers. - Established SecurityTestBase.cs as a base class for security tests, providing common infrastructure and mocking utilities. - Configured the test project StellaOps.Security.Tests.csproj with necessary dependencies for testing. --- .config/dotnet-tools.json | 12
