CVE-2026-33620Public exploitNetwork attack vector

API token disclosure via query-string authentication

Published Mar 26, 2026 · Updated Mar 26, 2026

Credential exposure in PinchTab 0.7.8 through 0.8.3 allows attackers to obtain API tokens from recorded query-string request URLs. The authentication middleware reads the token parameter from r.URL.Query and treats it as the bearer credential, while first-party setup and dashboard flows generate and consume tokenized URLs. Exposure requires a configured token, use of the query form, and access to a proxy log, browser or shell history, clipboard history, or tracing record; header-only clients are unaffected.
