TrustReport — REJECT

Findings (4)

src/login.py:42 · Source: arbiter_1

CRITICAL

SQL injection vulnerability: user input directly concatenated into query string without parameterization

query = "SELECT * FROM users WHERE name = '" + username + "'"

src/login.py:87 · Source: arbiter_2

HIGH

Password logged in plaintext to application log

logger.info(f"User {username} authenticated with password {password}")

src/session.py:23 · Source: opponent

MEDIUM

Session token lacks HttpOnly flag, vulnerable to XSS-based theft

Set-Cookie: session_id=abc123; Path=/

src/login.py:15 · Source: arbiter_1

LOW

Hardcoded timeout value (300s) without configuration option

TIMEOUT = 300 # seconds

CRITICAL

[security] SQL injection in login handler

Mitigation: Use parameterized queries

HIGH

[security] Plaintext password logging

Mitigation: Remove sensitive data from log statements

MEDIUM

[security] Missing HttpOnly on session cookie

Mitigation: Set HttpOnly=True

LOW

[performance] Hardcoded timeout limits scalability

Mitigation: Make timeout configurable via env var

Role	Model	Verdict	Score	Issues
Primary Auditor	gpt-4o	[FAIL]	42	SQL injection at line 42 Plaintext password in logs
Secondary Auditor	claude-3-5-sonnet	[FAIL]	38	Missing input validation on username field XSS risk in session cookie
Opposition (成本优化)	gpt-4o-mini	[PASS]	75	—

MEDIUM Race condition in session renewal

Reason: Arbiters disagree: one flags it, one considers it mitigated by DB transaction

Suggestion: Manual review of src/session.py:55-72 recommended

HIGH CSRF protection completeness

Reason: Adversarial test coverage incomplete — only 2 of 5 attack vectors covered

Suggestion: Expand adversarial test suite for CSRF scenarios
