## Affected

- lightdash: through 2.556.0

## Description

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.
