Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Perses versions from 0.43.0 before 0.54.0-rc.0 are affected. A user who holds only the datasource create permission can attach a secret they are not allowed to read, either to a saved datasource or through the unsaved datasource connectivity check, and then read the secret's plain text through the datasource proxy. Upgrade to 0.54.0-rc.0 or later. Until then, create datasources through provisioning and remove datasource create rights from users who should not hold them.
