CVE-2023-46729Network attack vector

SSRF via unsanitized tunnel rewrite parameters

Published Nov 10, 2023 · Updated Sep 3, 2024

SSRF in Sentry's Next.js SDK 7.26.0 through 7.76.0 allows remote attackers to send arbitrary HTTPS requests via a tunnel route. The generated Next.js rewrite accepts unrestricted o and p query values and embeds them into the ingestion hostname and API path. Exposure requires tunnelRoute to be enabled; crafted requests can reflect attacker-controlled responses or reach private-network services.
