Some checks failed
Aegis CI / lint-and-test (push) Has been cancelled
security: fix 6 vulnerabilities identified in SDLC audit
- fix(auth): enforce API key scopes in require_role/require_any_role;
  attach _api_key_scopes to user on API key auth; add require_scope()
  dependency — scopes were stored but never enforced (CWE-285)

- fix(sso): read SECURE_COOKIES env var for SSO cookie instead of
  hardcoded secure=False — SAML sessions now respect HTTPS config (CWE-614)

- fix(webhooks): SSRF prevention — validate webhook URLs against private
  and reserved CIDRs at creation/update time (CWE-918)

- fix(knowledge): restrict playbook/lesson create, update and restore
  to admin/red_lead/blue_lead roles — was open to any authenticated user (CWE-284)

- fix(alerts): restrict alert acknowledge/resolve/dismiss to admin/lead
  roles — any user could silence security alerts (CWE-284)

- security: delete get_admin_creds.py, check_auth.py, deploy.py scripts
  containing hardcoded root SSH credentials and production DB access;
  add scripts/.gitignore to prevent reintroduction (CWE-798)
