Executive Summary

This vulnerability is an authorization bypass in Lightdash versions up to 2.556.0. It allows authenticated organization members to delete other users' personal access tokens by supplying the victim's token UUID. Attackers can send DELETE requests to the personal-access-tokens route, even across organizations, to revoke tokens and disrupt API integrations.

Detection Guidance

To detect this vulnerability, monitor Lightdash API logs for DELETE requests to the /personal-access-tokens endpoint with a victim's token UUID. Check for unauthorized cross-organization token deletions or repeated failed attempts to delete tokens.

Impact Analysis

This vulnerability can lead to denial of service for any API integrations or automations relying on the revoked token. It does not involve data exposure or code execution but can break critical integrations by removing access tokens.

Compliance Impact

This vulnerability could impact compliance with GDPR and HIPAA by enabling unauthorized token revocation, potentially disrupting API integrations that handle sensitive data. Unauthorized deletion of personal access tokens may lead to loss of access to critical systems, affecting data processing integrity and availability required by these regulations.

Mitigation Strategies

Immediately update Lightdash to the latest version beyond 2.556.0. If updating is not possible, restrict DELETE permissions for personal access tokens to token owners only and implement ownership validation in the delete route.
