CVE-2026-50132: Budibase has an Account Impersonation Issue — Chat Identity Link Hijacking via Missing Consent & CSRF

June 22, 2026

DimensionDetail
ConfidentialityHigh — attacker reads all table rows, files, and knowledge base data accessible to victim
IntegrityHigh — attacker writes rows and triggers automations (email, external API calls, record creation) as victim
AvailabilityNone
Auth requiredLow — attacker only needs a Slack/Discord account in the same workspace as the Budibase bot
User interactionRequired — victim clicks one link (trivial social engineering in any enterprise Slack)
ScopeUnchanged — impact is within the victim’s Budibase tenant
PersistencePermanent — the link document persists in CouchDB until explicitly deleted; re-exploitation survives token rotation
