Gitlab GitLab 2023-04-15 CVSS v3.1

CVSS

5.3

Description

An issue was discovered in GitLab Community and Enterprise Edition before 11.1.7, 11.2.x before 11.2.4, and 11.3.x before 11.3.1. Attackers may have been able to obtain sensitive access-token data from Sentry logs via the GRPC::Unknown exception.

Summary dbcve.org

GitLab versions before 11.1.7, 11.2.x before 11.2.4, and 11.3.x before 11.3.1 improperly handle GRPC::Unknown exceptions, causing sensitive access tokens to be logged to Sentry error tracking. Attackers with access to Sentry logs could retrieve these tokens and gain unauthorized authentication.

Mitigation

Upgrade GitLab to version 11.1.7, 11.2.4, 11.3.1 or later to remediate the improper exception handling that exposes access tokens in Sentry logs.
