Description

WeKan versions prior to 8.19 contain an authorization vulnerability where certain card update API paths validate only board read access rather than requiring write permission. This can allow users with read-only roles to perform card updates that should require write access.

Affected products

WeKan: before 8.19 — fixed in 8.19

How to fix

Upgrade to a fixed version: WeKan 8.19. Check the vendor advisory for mitigations.
