Vulnerability from github – Published: 2026-09-02 15:34 – Updated: 2026-09-02 15:34

Details

Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') (CWE-22) in Elastic Maps Server can lead to information disclosure via Path Traversal (CAPEC-126). An unauthenticated attacker able to reach the service over the network could cause it to return the contents of files outside its intended content directory that are readable by the server process.

Severity

5.3 (Medium)
