CVE-2026-1896
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA vulnerability has been found in WeKan up to 8.20. Affected by this vulnerability is the function ComprehensiveBoardMigration of the file server/migrations/comprehensiveBoardMigration.js of the component Migration Operation Handler. The manipulation of the argument boardId leads to improper access controls. The attack is possible to be carried out remotely. Upgrading to version 8.21 addresses this issue. The identifier of the patch is cc35dafef57ef6e44a514a523f9a8d891e74ad8f. Upgrading the affected component is advised.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysisA user or process is granted a privilege it should not have, so anyone who reaches that path inherits capability beyond what was intended. Attackers seek out exactly these over-granted routes. The fix is assigning the minimum privilege required and verifying every grant explicitly rather than assuming it.
