CVE-2023-49094Network attack vector

Authenticated internal data disclosure via unrestricted URL fetching

Published Nov 30, 2023 · Updated Jun 5, 2025

Server-side request forgery in Sentry Symbolicator 0.3.3 through 23.11.1 allows remote authenticated users to read internal HTTP responses. Its HTTP source-fetching path accepts attacker-supplied endpoint URLs and follows them to internal IP addresses without restricting the destination. A registered Sentry account can submit the crafted endpoint and receive the fetched response through Symbolicator's API, exposing only data returned by the internal service.
