CVE-2025-65944
Sentry-Javascript deals with leaked sensitive headers when `sendDefaultPii` is set to `true`
Description
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.
