🚨 CRITICAL - Remote unauth file overwrite leads to code execution “Matryoshka Mail” (CVE-2026-13014) Thales CERT “Suspicious” application 1.3.4 is exposed to a remote, unauthenticated vulnerability that lets an attacker overwrite writable application files, including Python modules, configuration, cron inputs, and runtime artifacts inside the Django container. The underlying weakness is an arbitrary file overwrite / improper input validation flaw that fails to constrain attacker-controlled paths or file targets to safe locations. Exploitation is straightforward over the network with no credentials required, as the attacker can push crafted content that lands in writable directories and is later imported/executed by the app or scheduled jobs. Impact is severe: arbitrary code execution, persistent denial of service, theft of secrets/integration tokens, and potential root-level execution within the application container. 👉 Affected: Thales CERT “Suspicious” application 1.3.4 | No fix yet - treat as suspicious
