- Summary
- Parse Server session creation endpoint allows overwriting server-generated session fields
- Details
-
Impact
An authenticated user can overwrite server-generated session fields (
sessionToken,expiresAt,createdWith) when creating a session object viaPOST /classes/_Session. This allows bypassing the server's session expiration policy by setting an arbitrary far-future expiration date. It also allows setting a predictable session token value.Patches
The session creation endpoint now filters out server-generated fields from user-supplied data, preventing them from being overwritten.
Workarounds
Add a
beforeSavetrigger on the_Sessionclass to validate and reject or strip any user-supplied values forsessionToken,expiresAt, andcreatedWith. - Database specific
