CVE-2026-53575

EspoCRM is an open source customer relationship management application. Prior to 9.3.9, an authenticated administrator can place crafted content in the applicationName setting through CSP nonce injection. The persistent injection is inserted into the main application page without escaping, allowing attacker-controlled JavaScript to run in users' sessions and leak page data, including unsaved user input. This issue is fixed in version 9.3.9.
