Lifecycle Timeline
9DescriptionCVE.org
WeKan versions prior to 8.19 contain an authorization logic vulnerability where the instance configuration setting allowPrivateOnly is not sufficiently enforced at board creation time. When allowPrivateOnly is enabled, users can still create public boards due to incomplete server-side enforcement.
AnalysisAI
Authorization bypass in WeKan (self-hosted kanban board) versions prior to 8.19 lets an authenticated user create public boards even when the instance-wide allowPrivateOnly setting is enabled, because server-side enforcement of the visibility policy is incomplete at board-creation time. The flaw undermines an administrator's expectation that all boards remain private, potentially exposing board content beyond intended audiences. EPSS is low (0.03%, 9th percentile) with no public exploit identified at time of analysis and no CISA KEV listing; a vendor patch is available.
