The issue is related to the leakage of sensitive cookie values, including session cookies, to Sentry when using the Django integration of the Sentry SDK in a specific configuration. This can occur when the Sentry SDK configuration has `sendDefaultPII` set to `True`, a custom name is used for either `SESSION COOKIE NAME` or `CSRF COOKIE NAME` in Django settings, and data scrubbing features are not configured to account for the custom cookie names. The leaked cookies could be used by someone with access to Sentry issues to impersonate or escalate privileges within the application.
