CVE-2026-63130Network attack vectorHinoki check available

JSON-file tampering via unchecked label paths

Published Oct 15, 2026 · Updated Oct 15, 2026

Path traversal in EspoCRM before 9.3.10 allows remote authenticated users with administrator access to alter JSON files via Label Manager. LabelManager accepts language and scope values without restricting them to path basenames, and the Language utility incorporates them into JSON-file paths outside the intended directory. Administrator access is required, and reading, creating, modifying, or deleting JSON files is limited by server configuration and filesystem permissions.
