Lightdash through 2.556.0 contains an authorization bypass vulnerability that allows authenticated organization members to delete other users' personal access tokens by supplying their UUID. Attackers can send DELETE requests to the personal-access-tokens route with a victim's token UUID, even across organizations, to revoke it and break API integrations.

Lightdash version 0.1024.6 allows users with the necessary permissions, such as Administrator or Editor, to create and share dashboards. A dashboard that contains HTML elements which point to a threat actor controlled source can trigger an SSRF request when exported, via a POST request to /api/v1/dashboards//export. The forged request contains the value of the exporting user’s session token. A threat actor could obtain the session token of any user who exports the dashboard. The obtained session token can be used to perform actions as the victim on the application, resulting in session takeover.

Multiple stored cross-site scripting (“XSS”) vulnerabilities in the markdown dashboard and dashboard comment functionality of Lightdash version 0.1024.6 allows remote authenticated threat actors to inject malicious scripts into vulnerable web pages. A threat actor could potentially exploit this vulnerability to store malicious JavaScript which executes in the context of a user’s session with the application.

packages/backend/src/routers in Lightdash before 0.510.3 has insecure file endpoints, e.g., they allow .. directory traversal and do not ensure that an intended file extension (.csv or .png) is used.
