CVE-2026-47768Public exploit

API key disclosure via redirect query string

Published Jul 28, 2026 · Updated Jul 28, 2026

Sensitive-data exposure in juev nebula-mesh before 0.3.2 allows local users to read newly created operator API keys. The handleOperatorCreateAPIKey handler places each raw 32-byte bearer token in a 303 Location query string, exposing it to browser history, Referer headers, and intermediary access logs. An administrator must create the key, and exploitation requires access to the operator's browser history or infrastructure logs; disclosure grants the key's operator API privileges.
