Jeremie Fraeys	17d5c75e33	fix(security): Path validation improvements for symlink resolution ... Fix ValidatePath to correctly resolve symlinks and handle edge cases: - Resolve symlinks before boundary check to prevent traversal - Handle macOS /private prefix correctly - Add fallback for non-existent paths (parent directory resolution) - Double boundary checks: before AND after symlink resolution - Prevent race conditions between check and use Update path traversal tests: - Correct test expectations for "..." (three dots is valid filename, not traversal) - Add tests for symlink escape attempts - Add unicode attack tests - Add deeply nested traversal tests Security impact: Prevents path traversal via symlink following in artifact scanning and other file operations.	2026-02-23 19:44:16 -05:00
Jeremie Fraeys	fccced6bb3	test(security): add comprehensive security unit tests ... Adds 13 security tests across 4 files for hardening verification: **Path Traversal Tests (path_traversal_test.go):** - TestSecurePathValidator_ValidRelativePath - TestSecurePathValidator_PathTraversalBlocked - TestSecurePathValidator_SymlinkEscape - Tests symlink resolution and path boundary enforcement **File Type Validation Tests (filetype_test.go):** - TestValidateFileType_AllowedTypes - TestValidateFileType_DangerousTypesBlocked - TestValidateModelFile - Tests magic bytes validation and dangerous extension blocking **Secrets Management Tests (secrets_test.go):** - TestExpandSecrets_BasicExpansion - TestExpandSecrets_NestedAndMissingVars - TestValidateNoPlaintextSecrets_HeuristicDetection - Tests env variable expansion and plaintext secret detection with entropy **Audit Logging Tests (audit_test.go):** - TestAuditLogger_ChainIntegrity - TestAuditLogger_VerifyChain - TestAuditLogger_LogFileAccess - TestAuditLogger_Disabled - Tests tamper-evident chain hashing and file access logging	2026-02-23 18:00:45 -05:00
