Sentry-Javascript deals with leaked sensitive headers when `sendDefaultPii` is set to `true`
Sentry-Javascript is an official Sentry SDKs for JavaScript. From version 10.11.0 to before 10.27.0, when a Node.js application using the Sentry SDK has sendDefaultPii: true it is possible to inadvertently send certain sensitive HTTP headers, including the Cookie header, to Sentry. Those headers would be stored within a Sentry organization as part of the associated trace. A person with access to the Sentry organization could then view and use these sensitive values to impersonate or escalate their privileges within the application. This issue has been patched in version 10.27.0.
### Impact
The [ContextLines integration](https://docs.sentry.io/platforms/javascript/guides/node/configuration/integrations/contextlines/) uses readable streams to more efficiently use memory when reading files. The ContextLines integration is used to attach source context to outgoing events.
The stream was not explicitly closed after use. This could lead to excessive amounts of file handles open on the system and potentially lead to a Denial of Service (DoS).
The ContextLines integration is enabled by default in the Node SDK (`@sentry/node`) and SDKs that run in Node.js environments (`@sentry/astro`, `@sentry/aws-serverless`, `@sentry/bun
