Perses: Missing authorization in datasource proxy allows cross-scope secret disclosure

CVSS 4.0 8.3 HIGHCheck source for fixed versionsKEV status unknown

Published

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.
