Sentry is an error tracking and performance monitoring platform. Starting in version 22.1.0 and prior to version 23.7.2, an attacker with access to a token with few or no scopes can query /api/0/api-tokens/ for a list of all tokens created by a user, including tokens with greater scopes, and use those tokens in other requests. There is no evidence that the issue was exploited on sentry.io.

For self-hosted users, it is advised to rotate user auth tokens. A fix is available in version 23.7.2 of sentry and self-hosted. There are no known workarounds.
