EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 7.2 under NVD CVSS v3. EPSS exploit probability: 0.4%, top 63% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

EspoCRM is an open source customer relationship management application. Prior to version 9.3.4, the admin template management endpoints accept attacker-controlled name and scope values and pass them into template path construction without normalization or traversal filtering. As a result, an authenticated admin can use ../ sequences to escape the intended template directory and read, create, overwrite, or delete arbitrary files that resolve to body.tpl or subject.tpl under the web application user's filesystem permissions. Version 9.3.4 fixes the issue.
