Summary

Vulnerable versions of `loopback` may allow attackers to create Authentication Tokens on behalf of other users due to Improper Authorization. If the AccessToken model is publicly exposed, an attacker can create Authorization Tokens for any user as long as they know the target's `userId`. This will allow the attacker to access the user's data and their privileges.

## Recommendation

For loopback 2.x, upgrade to version 2.40.0 or later For loopback 3.x, upgrade to version 3.22.0 or later

Patch / fix

  • npm loopback 2.40.0, 3.22.0

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
