description

OpenProject 17.2.0 and later contain an authorization flaw in the in-place project attribute editing endpoint. Attackers who can view a project can trigger unintended project operations or access information beyond their permissions; on public instances without required login, this may include anonymous users.

mitigation

Upgrade OpenProject to 17.5.2, 17.6.1, 17.7.3, 17.9.7, 17.8.2 or later.

fixed in 17.5.2, 17.6.1, 17.7.3, 17.9.7, 17.8.2
