Moderate severity GitHub Reviewed Published Jun 20, 2023 in remult/remult • Updated Nov 9, 2023

Package

npm remult (npm)

Affected versions

< 0.20.6

Patched versions

Description

Impact

If you used the apiPrefilter option of the @Entity decorator, by setting it to a function that returns a filter that prevents unauthorized access to data, an attacker who knows the id of an entity instance she is not authorized to access, can gain read, update and delete access to it.

Patches

The issue is fixed in version 0.20.6

Workarounds

Set the apiPrefilter option to a filter object instead of a function.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
