Package

npm payload (npm)

Affected versions

< 1.7.0

Patched versions

1.7.0

Description

Details

If a user has access to documents that contain hidden fields or fields they do not have access to, the user could reverse-engineer those values via brute force.

Affected versions: < 1.7.0

Workarounds

If you are unable to update, you can write a beforeOperation hook to remove where queries that attempt to access hidden field data.

Detecting Compromise

Monitor your instance for brute-force style requests against your instance using where queries.

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.
