CVE-2026-48050 (opens in a new tab)How to fix?
Upgrade github.com/basekick-labs/arc/internal/api to version 26.06.1 or higher.
Overview
Affected versions of this package are vulnerable to Missing Authentication for Critical Function via unauthenticated access to the /debug/pprof endpoints. An attacker can retrieve sensitive runtime information, including in-memory state, call stacks, and authentication cache data, or exhaust CPU resources by making crafted HTTP requests to these endpoints. This can be achieved without authentication, rate limiting, or resource constraints, allowing remote exploitation.
Workaround
This vulnerability can be mitigated by blocking /debug/pprof* at a reverse proxy or load balancer, restricting the API port to trusted networks via firewall rules, or commenting out app.Use(pprof.New()) in the relevant server file and rebuilding.
