Alek-Sentry

**Name of the Vulnerable Software and Affected Versions** Sentry's Astro SDK versions 7.78.0 through 7.86.0 **Description** A ReDoS (Regular expression Denial of Service) vulnerability has been identified in Sentry's Astro SDK. 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 they're using Sentry instrumentation, have manually registered Sentry Middleware, or have configured Astro in SSR (server) or hybrid mode. They must also have configured routes with at least two path params. **Recommendations** For versions 7.78.0 through 7.86.0, upgrade to version 7.87.0 to patch the vulnerability. As a temporary workaround, consider disabling auto instrumentation if you're using Astro 3.5.0 or newer, and remove the manually added Sentry middleware. This will prevent the vulnerability from being exploited, but some details such as server-side transactions will be omitted.

**Name of the Vulnerable Software and Affected Versions** sentry-javascript versions prior to 7.77.0 **Description** The issue is related to insufficient input validation in the sentry-javascript SDK, specifically affecting the Next.js SDK tunnel endpoint. This allows an attacker to send HTTP requests to arbitrary URLs and reflect the response back to the user, potentially leading to client-side vulnerabilities such as XSS/CSRF, interaction with internal networks, reading cloud metadata endpoints, or local/remote port scans. The problem only affects users with the Next.js SDK tunneling feature enabled. **Recommendations** For versions prior to 7.77.0, update to version 7.77.0 to fix the issue. As a temporary workaround, consider disabling the tunneling feature by removing the `tunnelRoute` option from the Sentry Next.js SDK config in `next.config.js` or `next.config.mjs`.
