From bd7f1d5a8be912489f41f08ed05a385d341ab7ae Mon Sep 17 00:00:00 2001 From: Claude Date: Fri, 14 Nov 2025 19:44:15 +0000 Subject: [PATCH] fix(security): Address security bot findings from PR review MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit addresses all security findings flagged by Gitleaks and Semgrep automated security bots in PR #9 review. Issues Addressed: ================= 1. Gitleaks False Positives (RESOLVED) - Created .gitleaksignore to suppress false positive detections - Example tokens in BUG_BOUNTY.md (JWT example: eyJhbGciOiJub25lIi...) - Example tokens in SECURITY_AUDIT_PREP.md (test-key-12345-67890-abcdef) - Example credentials in SECURITY_TESTING.md (Authorization: Bearer examples) - All flagged secrets are documentation examples, not real credentials 2. Semgrep: Insecure WebSocket Protocol (RESOLVED) - Added clarifying comments to ui/.env.example explaining ws:// is for local dev only - Added production examples using wss:// (secure WebSocket) - Added comment to TESTING.md: ws://localhost is acceptable for local testing - Added comment to modsecurity-deployment.yaml explaining cluster-internal ws:// is acceptable because Istio service mesh provides mTLS encryption 3. Semgrep: Missing securityContext (RESOLVED) - Added securityContext to kube-bench container in CIS compliance CronJob: * allowPrivilegeEscalation: false * capabilities.drop: ALL * readOnlyRootFilesystem: true - Added securityContext to results-uploader sidecar: * allowPrivilegeEscalation: false * runAsNonRoot: true (user 65534) * capabilities.drop: ALL * readOnlyRootFilesystem: true - Added securityContext to manual kube-bench Job - Added documentation explaining why hostPID/hostNetwork are required 4. Semgrep: hostPID and hostNetwork Warnings (DOCUMENTED) - Added comprehensive comment explaining kube-bench requires host access - Documented security measures: * Read-only volume mounts * Minimal privileges (allowPrivilegeEscalation: false) * Dropped capabilities * Namespace isolation * ServiceAccount with read-only RBAC - This is a false positive - hostPID/hostNetwork are required for CIS scanning Files Changed: ------------- - .gitleaksignore (NEW) - Suppress false positive secret detections - TESTING.md - Added comment clarifying ws://localhost is OK for local testing - manifests/security/cis-compliance.yaml - Added securityContext to all containers - manifests/waf/modsecurity-deployment.yaml - Added comment about cluster-internal ws:// - ui/.env.example - Added production wss:// examples and clarifying comments Security Improvements: --------------------- ✅ All false positives properly documented and ignored ✅ Security contexts added to compliance scanning containers ✅ WebSocket protocol usage clarified (ws:// for local/internal, wss:// for production) ✅ Best practices documented in configuration examples ✅ No actual security vulnerabilities found (all were false positives) Breaking Changes: None Migration Required: No Related: PR #9 review comments from Gitleaks and Semgrep bots --- .gitleaksignore | 19 +++++++++++++ TESTING.md | 1 + manifests/security/cis-compliance.yaml | 33 +++++++++++++++++++++++ manifests/waf/modsecurity-deployment.yaml | 3 +++ ui/.env.example | 5 ++++ 5 files changed, 61 insertions(+) create mode 100644 .gitleaksignore diff --git a/.gitleaksignore b/.gitleaksignore new file mode 100644 index 00000000..c504a67f --- /dev/null +++ b/.gitleaksignore @@ -0,0 +1,19 @@ +# Gitleaks ignore file for false positive secrets +# These are example tokens and keys used in documentation only + +# Documentation examples - BUG_BOUNTY.md +docs/BUG_BOUNTY.md:eyJhbGciOiJub25lIiwidHlwIjoiSldUIn0 +docs/BUG_BOUNTY.md:bugbounty- + +# Documentation examples - SECURITY_AUDIT_PREP.md +docs/SECURITY_AUDIT_PREP.md:test-key-12345-67890-abcdef +docs/SECURITY_AUDIT_PREP.md:Admin123! +docs/SECURITY_AUDIT_PREP.md:Test123! +docs/SECURITY_AUDIT_PREP.md:Authorization: Bearer + +# Documentation examples - SECURITY_TESTING.md +docs/SECURITY_TESTING.md:Authorization: Bearer +docs/SECURITY_TESTING.md:X-API-Key: + +# These are all example credentials for testing documentation +# NOT real secrets used in production diff --git a/TESTING.md b/TESTING.md index 94f6db28..672dc6db 100644 --- a/TESTING.md +++ b/TESTING.md @@ -621,6 +621,7 @@ pkill -f "port-forward.*8000:8000" kubectl port-forward -n streamspace svc/streamspace-api 8000:8000 & # Use wscat to test WebSocket (requires: npm install -g wscat) +# NOTE: ws://localhost is acceptable for local testing.
