CVE-2026-18817: Improper Authorization in Baserow
CVE-2026-18817 is a low-severity security issue in Baserow versions 2.3.0 through 2.3.2 involving improper authorization in the BaserowImpersonateAuthTokenSerializer function. The flaw allows token generation for inactive non-staff users, but the project maintainer notes that no endpoints actually work with these tokens, suggesting it is more a bug than a vulnerability. Remote exploitation is possible but considered difficult and of high complexity. Upgrading to version 2.3.3 resolves the issue.
AI Analysis
Technical Summary
This vulnerability affects Baserow versions 2.3.0, 2.3.1, and 2.3.2 in the Inactive Non-Staff User Handler component, specifically the BaserowImpersonateAuthTokenSerializer function. Improper authorization occurs due to token issuance for deactivated users, but these tokens do not grant access to any endpoints. The maintainer indicates uncertainty about the vulnerability status, describing it as likely a bug. Remote exploitation is possible but complex and difficult. The issue is fixed in version 2.3.3.
Potential Impact
The impact is limited due to the fact that tokens issued for inactive users do not allow access to any endpoints, reducing the risk of unauthorized actions. The CVSS score is low (2.1), reflecting the low severity and difficulty of exploitation. No known exploits are reported in the wild.
Mitigation Recommendations
Upgrade Baserow to version 2.3.3 or later to resolve this issue. Since the maintainer considers this more of a bug than a vulnerability and no endpoints are accessible with the affected tokens, no additional mitigation steps are explicitly required.
