Summary
EspoCRM before 9.3.10 contains a path traversal flaw (CWE-22) in the administrative Label Manager. An authenticated administrator can supply crafted input that moves file paths outside the intended directory. This lets the administrator read, modify, create or delete JSON files the application can access, subject to filesystem permissions and server configuration.

Description from the CNA
EspoCRM is an open source customer relationship management application. Prior to 9.3.10, an authenticated administrator can provide crafted input to the administrative Label Manager. Insufficient path validation allows traversal outside the intended directory and permits reading, modifying, creating, or deleting JSON files accessible to the application, subject to filesystem permissions and server configuration. This issue is fixed in version 9.3.10.
