{"apiVersion":"1.0","identifier":"CVE-2026-48050","description":"Arc is an open, SQL-native time-series database for telemetry. Versions prior to 26.06.1 register Go-s `net/http/pprof` handlers at `/debug/pprof/*` via `app.Use(pprof.New())` in `internal/api/server.go`, and `/debug/pprof` is added to `PublicPrefixes` in `cmd/arc/main.go`. The auth middleware short-circuits before the token check on prefix match, so the endpoints are reachable without any authentication. Version 26.06.1 contains a patch. Some workarounds are available. Block `/debug/pprof*` at a reverse proxy / load balancer in front of Arc, restrict Arc-s API port to known-trusted networks via firewall rules, and/or patch the running build: comment out `app.Use(pprof.New())` in `internal/api/server.go` and rebuild.","publishedAt":"2026-08-21T23:16:25","lastModifiedAt":"2026-08-25T17:17:14","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-48050","cvssScore":8.8,"cvssVector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","epssProbability":0.00358,"riskScore":0.91,"affectedProduct":"Arc","affectedVersions":"<26.06.1","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-48050","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-48050","en":"https://www.redsauce.net/en/cves/CVE-2026-48050","fr":"https://www.redsauce.net/fr/cves/CVE-2026-48050","pt":"https://www.redsauce.net/pt/cves/CVE-2026-48050","de":"https://www.redsauce.net/de/cves/CVE-2026-48050","sk":"https://www.redsauce.net/sk/cves/CVE-2026-48050","el":"https://www.redsauce.net/el/cves/CVE-2026-48050"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-48050"}}
