CVE-2023-28117

Sentry SDK is the official Python SDK for Sentry, real-time crash reporting software. When using the Django integration of versions prior to 1.14.0 of the Sentry SDK in a specific configuration it is possible to leak sensitive cookies values, including the session cookie to Sentry. These sensitive cookies could then be used by someone with access to your Sentry issues to impersonate or escalate their privileges within your application. In order for these sensitive values to be leaked, the Sentry SDK configuration must have `sendDefaultPII` set to `True`; one must use a custom name for either `SESSION_COOKIE_NAME` or `CSRF_COOKIE_NAME` in one's Django settings; and one must not be configured in one's organization or project settings to use Sentry's data scrubbing features to account for the custom cookie names. As of version 1.14.0, the Django integration of the `sentry-sdk` will detect the custom cookie names based on one's Django settings and will remove the values from the payload before sending the data to Sentry. As a workaround, use the SDK's filtering mechanism to remove the cookies from the payload that is sent to Sentry. For error events, this can be done with the `before_send` callback method and for performance related events (transactions) one can use the `before_send_transaction` callback method. Those who want to handle filtering of these values on the server-side can also use Sentry's advanced data scrubbing feature to account for the custom cookie names. Look for the `$http.cookies`, `$http.headers`, `$request.cookies`, or `$request.headers` fields to target with a scrubbing rule.

### Impact When using the [Django integration](https://docs.sentry.io/platforms/python/guides/django/) of the Sentry SDK in a specific configuration it is possible to leak sensitive cookies values, including the session cookie to Sentry. These sensitive cookies could then be used by someone with access to your Sentry issues to impersonate or escalate their privileges within your application. The below must be true in order for these sensitive values to be leaked: 1. Your Sentry SDK configuration has `sendDefaultPII` set to `True` 2. You are using a custom name for either of the cookies below in your Django settings. - [`SESSION_COOKIE_NAME`](https://docs.djangoproject.com/en/4.1/ref/settings/#std-setting-SESSION_COOKIE_NAME) or - [`CSRF_COOKIE_NAME`](https://docs.djangoproject.com/en/4.1/ref/settings/#std-setting-CSRF_COOKIE_NAME) Django settings 3. You are not configured in your organization or project settings to use [our data scrubbing features](https://docs.sentry.io/product/data-management-settings/scrubbing/) to account for the custom cookie names ### Patches As of version `1.14.0`, the Django integration of the `sentry-sdk` will detect the custom cookie names based on your Django settings and will remove the values from the payload _before_ sending the data to Sentry. ### Workarounds If you can not update your `sentry-sdk` to a patched version than you can use the SDKs filtering mechanism to remove the cookies from the payload that is sent to Sentry. For error events this can be done with the [before_send](https://docs.sentry.io/platforms/python/configuration/filtering/#using-platformidentifier-namebefore-send-) callback method and for performance related events (transactions) you can use the [before_send_transaction](https://docs.sentry.io/platforms/python/configuration/filtering/#using-platformidentifier-namebefore-send-transaction-) callback method. If you'd like to handle filtering of these values on the server-side, you can also use our [advanced data scrubbing feature](https://docs.sentry.io/product/data-management-settings/scrubbing/advanced-datascrubbing/) to account for the custom cookie names.
