CVE-2026-18817
Published:August 04, 2026
Updated:August 06, 2026
A security flaw has been discovered in Baserow up to 2.3.2. Affected by this issue is the function BaserowImpersonateAuthTokenSerializer of the file backend/src/baserow/api/admin/users/serializers.py of the component Inactive Non-Staff User Handler. Performing a manipulation results in improper authorization. Remote exploitation of the attack is possible. The complexity of an attack is rather high. The exploitation is known to be difficult. The presence of this vulnerability remains uncertain at this time. Upgrading to version 2.3.3 can resolve this issue. The affected component should be upgraded. The project maintainer explains: "While the problem exists, I'm not really sure if it's a vulnerability. (....) Even though the back gives a token for a deactivate user, none of the endpoints actually work. That said, we will fix it, but so far it seems more like a bug instead of a vulnerability."
