• Severity: high (CVSS 7.1 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.4% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-10-16 · updated 2026-10-26

Description

A flaw was found in WildFly. A user with the `Monitor` role, which is the lowest standard Role-Based Access Control (RBAC) role, can exploit a path traversal vulnerability in the `take-snapshot` operation. By manipulating the `name` parameter, this user can write a copy of the server configuration to an arbitrary location. This allows the `Monitor` role to read back the server configuration, including sensitive credentials, which would otherwise be restricted by RBAC, leading to information disclosure.
