Description

An issue was discovered in Wekan The Open Source kanban board system up to version 18.15, fixed in 18.16. Attachment upload API treats the Authorization bearer value as a userId and enters a non-terminating body-handling branch for any non-empty bearer token, enabling trivial application-layer DoS and latent identity-spoofing.
