### Impact A ReDoS (Regular expression Denial of Service) vulnerability has been identified in Sentry's Astro SDK 7.78.0-7.86.0. Under certain conditions, this vulnerability allows an attacker to cause excessive computation times on the server, leading to denial of service (DoS).

Applications that are using Sentry's Astro SDK are affected if:

1. They're using Sentry instrumentation: - they have [manually registered](https://docs.sentry.io/platforms/javascript/guides/astro/manual-setup/#manually-add-server-instrumentation) Sentry Middleware (affected versions 7.78.0-7.86.0); - or [configured](https://docs.sentry.io/platforms/javascript/guides/astro/manual-setup/#configure-server-instrumentation) Astro in SSR (server) or hybrid mode, use Astro 3.5.0 and newer and didn’t [disable the automatic server instrumentation](https://docs.sentry.io/platforms/javascript/guides/astro/manual-setup/#disable-auto-server-instrumentation) (affected versions 7.82.0-7.86.0). 2. They have configured routes with at least two path params (e.g. `/foo/[p1]/bar/[p2]`).

### Patches The problem has been patched in [@sentry/astro@7.87.0](https://www.npmjs.com/package/@sentry/astro/v/7.87.0). The corresponding PR: https://github.com/getsentry/sentry-javascript/pull/9815

### Workarounds We strongly recommend upgrading to the latest SDK version. However, if it's not possible, the steps to mitigate the vulnerability without upgrade are: * [disable auto instrumentation](https://docs.sentry.io/platfo…
