Doc Text:
A flaw was found in Perses, an open-source dashboard and visualization project. A low-privilege user with datasource creation rights can exploit a missing authorization check in the datasource proxy. This allows the user to attach a project or global secret they cannot otherwise read and cause Perses to send the decrypted secret in plaintext to a service controlled by the attacker. This bypasses project and global scope separation, leading to the disclosure of sensitive information.

Description OSIDB Bzimport 2026-09-22 21:03:01 UTC 
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.
