CyberRota Analysis

AI-Generated

The vulnerability affects Perses versions 0.43.0 to 0.54.0-rc.0, allowing low-privilege users to exploit datasource creation paths to access sensitive project or global Secrets without proper permissions. This can lead to the exposure of decrypted secrets in plaintext, compromising data confidentiality and potentially impacting the security of services controlled by the attacker. Organizations using affected versions of Perses should prioritize upgrading to version 0.54.0-rc.0 to mitigate this high-severity risk.

Original NVD Description

Perses is an open-source dashboard and visualization project for observability data. From 0.43.0 until 0.54.0-rc.0, the datasource creation and unsaved datasource proxy paths authorize the caller on a Datasource or GlobalDatasource scope but do not require read permission for the separately grantable associated project or global Secret before resolving it. A low-privilege user with GlobalDatasource:create or corresponding project datasource creation rights can attach a project or global Secret that the user cannot otherwise read, point the datasource at a service controlled by the user, and cause Perses to send the decrypted secret in plaintext, bypassing project and global scope separation. This issue is fixed in version 0.54.0-rc.0.
