CVE-2026-18817
LowCVSS 2.2Exploitation Probability (EPSS)
Low risk10th percentile - higher than 10% of all known CVEs
Summary
Baserow up to version 2.3.2 has an issue in the BaserowImpersonateAuthTokenSerializer function within the Inactive Non-Staff User Handler component, leading to improper authorization. Remote exploitation is possible but requires high complexity. The maintainer suggests it may be more of a bug than a vulnerability, but recommends upgrading to 2.3.3.
Risk Assessment
Potential risk of unauthorized access or token manipulation, though the maintainer indicates the actual impact may be limited because tokens for inactive users do not work on any endpoint.
Recommendation
Upgrade Baserow to version 2.3.3 or later to resolve this issue.
Original NVD description (English source)
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."
