Exceptions message that may contain sensitive information can leak

Moderate
soyuka published GHSA-rfw5-cqjj-7v9r Apr 3, 2025

Package

composer api-platform/core (Composer)

Affected versions

3.2.0

Patched versions

3.2.5

Description

Summary

Exception messages, that are not HTTP exceptions, are visible in the JSON error response.

Details

While we wanted to make our errors compatible with the JSON Problem specification, we ended up handling more exceptions then we did previously (introduced at #5823). Instead of leaving that to Symfony, we ended up serializing errors with our normalizers which lead to not hiding the exception details. Note that the trace is hidden in production but the message is not, and the message can contain sensitive information.

PoC

At https://github.com/ili101/api-platform/tree/test3.2 it triggers an authentication exception as LDAP is not reachable. You can find the message available as a JSON response when trying to reach an endpoint.

Impact

Version 3.2 until 3.2.4 is impacted.

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.
