Search: CVE-2026-48050

CVE-2026-48050 is a high-severity vulnerability in Basekick-Labs' Arc time-series database prior to version 26.06.1. The issue arises because the application registers Go's pprof debugging endpoints under /debug/pprof/* without proper authentication, allowing unauthorized access to sensitive profiling information. This exposure occurs due to the authentication middleware bypassing token checks for these endpoints. The vulnerability is patched in version 26.06.1. Workarounds include blocking access to /debug/pprof* at the reverse proxy or load balancer, restricting API port access via firewall rules, or disabling the pprof handler in the source code and rebuilding the application.
