CVE-2026-18817: Improper Authorization in Baserow
CVE-2026-18817 is a low-severity security issue in Baserow versions 2.3.0, 2.3.1, and 2.3.2 involving improper authorization in the BaserowImpersonateAuthTokenSerializer function. The flaw allows manipulation that results in improper authorization, but the project maintainer notes that while a token is issued for a deactivated user, none of the endpoints actually function with it, suggesting it is more a bug than a vulnerability. Upgrading to version 2.3.3 resolves the issue.
AI Analysis
Technical Summary
This vulnerability affects Baserow up to version 2.3.2 in the Inactive Non-Staff User Handler component, specifically the BaserowImpersonateAuthTokenSerializer function. It allows an attacker with high privileges to manipulate authorization tokens for deactivated users, potentially bypassing intended restrictions. However, the maintainer indicates that the tokens issued do not grant access to any endpoints, making exploitation difficult and the security impact minimal. The issue is fixed in version 2.3.3.
Potential Impact
The impact is low due to the high complexity of exploitation and the fact that tokens issued for deactivated users do not grant access to any endpoints. There is no known exploitation in the wild. The vulnerability does not allow unauthorized access to functionality or data beyond what is already permitted.
Mitigation Recommendations
Upgrade affected Baserow instances from versions 2.3.0, 2.3.1, or 2.3.2 to version 2.3.3 where the issue is resolved. Since the maintainer considers this more a bug than a vulnerability and no endpoints are accessible with the token, no urgent action is required beyond applying the update.
