CVE-2026-27073Network attack vector

Password recovery exploitation via hard-coded callback credentials

Published Mar 25, 2026 · Updated Mar 25, 2026

Hard-coded credentials in Addi – Cuotas que se adaptan a ti 2.0.4 and earlier allow remote attackers to exploit password recovery. The callback authentication path embeds credentials instead of fetching per-merchant values from Addi’s API, leaving a shared secret recoverable from distributed plugin code. No authentication or user interaction is required; the credential permits unauthorized callback authentication and payment-state changes, with no reported disclosure or service interruption.
