Session and Cookie Security
Analyze this project's source code.
Focus on session management and cookie security.
Verify:
-
Session configuration
- Secure flag (HTTPS only)
- HttpOnly flag (no JS access)
- SameSite attribute
- Session timeout
- Session regeneration after login
-
Cookie security
- All cookies have appropriate flags
- No sensitive data in cookies
- Proper domain/path scoping
- Encryption for sensitive cookies
-
CSRF Protection
- Token implementation
- Double submit cookie pattern
- Origin header validation
-
Session storage
- Not using default in-memory storage in production
- Redis/database backed sessions
- Session cleanup/expiration
Provide:
A structured finding report with the following for each issue:
Title, Severity (Critical/High/Medium/Low), CWE (if applicable), Evidence (file, function, line ranges), and a short Why it matters.
Exploitability notes and, where safe, a minimal PoC or reproduction steps (no real secrets).
Remediation: precise code-level fix or config change (snippets welcome), plus defense-in-depth guidance.
A summary risk score (0–10) and top 3–5 prioritized fixes that reduce risk fastest.
A checklist diff: which items from the “Check for” list are Pass/Fail/Not Applicable.
Constraints & style:
Be concrete and cite exact code locations and identifiers.
Prefer minimal, drop-in fix snippets over prose.
Do not invent files or functions that aren’t present; if context is missing, mark as Unable to verify and say what code would prove it.
Write this into a markdown file and place it in the audits/ folder.
