Quick Start

1. Create Jira ticket first

See global/rules/jira-ticket-workflow.md for ticket creation.

2. Get alerts by severity

REPO=$(gh repo view --json nameWithOwner -q '.nameWithOwner')
gh api --paginate repos/$REPO/dependabot/alerts --jq '.[] | select(.state == "open") | {
  number, severity: .security_advisory.severity, package: .dependency.package.name,
  patched_version: .security_vulnerability.first_patched_version.identifier,
  cve: .security_advisory.cve_id
}'

3. Fix by severity (CRITICAL first, then HIGH, MEDIUM, LOW)

See references/fix-strategies.md for strategy hierarchy.

4. Verify with dependency graph

./gradlew -I gradle/dependency-graph-init.gradle \
    --dependency-verification=off \
    :ForceDependencyResolutionPlugin_resolveAllDependencies

# Check ONLY patched versions appear
grep -i "package-name" build/reports/dependency-graph-snapshots/dependency-list.txt

5. Commit and create PR

git commit -m "🤖 🛡️ fix(security): [JIRA-KEY] resolve CRITICAL vulnerabilities"

Key Concepts

Severity-Based Processing

Process ONE severity level at a time, creating separate PRs for each:

Priority	Severity	When to Process
1	CRITICAL	Always first
2	HIGH	After no CRITICAL
3	MEDIUM	After no HIGH
4	LOW	After no MEDIUM

Dependency Graph vs Runtime Resolution

The dependency graph plugin reports ALL versions to GitHub, not just the resolved version. Force rules alone won't fix dependency-review failures - use substitution to remove old versions.

Fix Strategy Hierarchy

BOM Update - Update Spring Boot, gRPC, Protobuf BOM versions
Version Catalog - Update direct dependencies in libs.versions.toml
Dependency Substitution - Replace transitive dependencies
Constraints - Set minimum version floors
Force Rules - Quick fix (combine with substitution)
Exclude + Add - Last resort
