Prior to 2026.04.1, shared-base sessions were granted the same base-member capabilities as authenticated viewers. Using only the shared-base UUID (xc-shared-base-id), an attacker could enumerate base members and invite an arbitrary email into the base as a real member. The invited user could then redeem the invite via the normal signup flow and retain authenticated access even after the owner revoked the shared link. Shared-base sessions were mapped to ProjectRoles.VIEWER in packages/nocodb/src/strategies/base-view.strategy/base-view.strategy.ts, and packages/nocodb/src/utils/acl.ts granted baseUserList and userInvite to that role. The shared frontend (packages/nc-gui/composables/useApi/interceptors.ts) deliberately removed auth headers in favour of the shared-base header, but the ACL middleware did not distinguish shared sessions from genuine viewers. This vulnerability is fixed in 2026.04.1."}], "source": {"advisory": "GHSA-chqv-vrj7-qffp", "discovery": "UNKNOWN"}}}}
