Description

Vendure vulnerable to timing attack that enables user enumeration in NativeAuthenticationStrategy

Summary

The NativeAuthenticationStrategy.authenticate() method is vulnerable to a timing attack that allows attackers to enumerate valid usernames (email addresses).

Details

In packages/core/src/config/auth/native-authentication-strategy.ts, the authenticate method returns immediately if a user is not found:

```typescript

const user = await this.userService.getUserByEmailAddress(ctx, data.username);

if (!user) {

return false; // Instant return (~1-5ms)

}

const passwordMatch = await this.verifyUserPassword(ctx, user.id, data.password);

// Password check takes ~200-400ms with bcrypt (12 rounds)

```

The significant timing difference (~200-400ms for bcrypt vs ~1-5ms for DB miss) allows attackers to reliably distinguish between existing and non-existing accounts.

Impact

  • Attackers can enumerate valid user accounts
  • Enables targeted brute-force or phishing attacks
  • Information disclosure (account existence)

Recommended Fix

Perform a dummy bcrypt check when user is not found to ensure consistent response times.

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is low, an attacker needs no privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality low, integrity none, availability none.

CVSS metrics in full

The score comes from this vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N

  • Attack vector: Network — reachable from anywhere that can route to the service.
  • Attack complexity: Low — the attack works reliably, with no preparation.
  • Privileges required: None — an unauthenticated stranger can try it.
  • User interaction: None — nobody has to be tricked into anything.
  • Scope: Unchanged — the damage stays inside the vulnerable component.
  • Confidentiality impact: Low — limited, and the attacker does not choose what is affected.
  • Integrity impact: None.
  • Availability impact: None.
