EspoCRM: Admin path traversal in LabelManager (Custom Label saving) allows arbitrary `.json` file read, write and delete

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

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.
