CVE-2026-84823Network attack vector

Credential disclosure via snapshot path traversal

Published Oct 15, 2026 · Updated Oct 15, 2026

Path traversal in WildFly's take-snapshot operation allows remote authenticated users to read server configuration, including credentials. The operation accepts a manipulated name parameter that redirects a configuration copy to an arbitrary location for subsequent readback. Exploitation requires management access with the Monitor role and bypasses its restrictions on sensitive configuration data.
