Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Perses versions before 0.54.0-beta.3 (Go module github.com/perses/perses) contain an authorization bypass in the project query parameter. An authenticated user with only viewer access to one project can read dashboards and datasource specifications, along with variables, from other projects. Upgrade to 0.54.0-beta.3 or later; the source lists no workaround.
