9.6.0-alpha.12- Upgrade parse-server to this version or later
Description
Impact
An unauthenticated attacker can take over any user account that was created with an authentication provider that does not validate the format of the user identifier (e.g. anonymous authentication). By sending a crafted login request, the attacker can cause the server to perform a pattern-matching query instead of an exact-match lookup, allowing the attacker to match an existing user and obtain a valid session token for that user's account. Both MongoDB and PostgreSQL database backends are affected. Any Parse Server deployment that allows anonymous authentication (enabled by default) is vulnerable.
Patches
The fix enforces that the user identifier in authentication data is a string before using it in a database query. Non-string values are rejected with a validation error.
Workarounds
There is no known workaround.

How to fix
Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.
parse-server npm → 9.6.0-alpha.12
- npm
npm install parse-server@9.6.0-alpha.12- yarn
yarn add parse-server@9.6.0-alpha.12- pnpm
