Summary

### Impact In case a Prototype Pollution vulnerability is present in a user's application or bundled libraries, the Sentry SDK could potentially serve as a gadget to exploit that vulnerability. The exploitability depends on the specific details of the underlying Prototype Pollution issue. > [!NOTE] > This advisory does not indicate the presence of a Prototype Pollution within the Sentry SDK itself. Users are strongly advised to first address any Prototype Pollution vulnerabilities in their application, as they pose a more critical security risk. ### Patches The issue was patched in all Sentry JavaScript SDKs starting from the [8.33.0](https://github.com/getsentry/sentry-javascript/releases/tag/8.33.0) version.
