CVE-2026-17614 · Severity: medium · CVSS 4.4 · Published 2026-08-04

WildFly is an open-source Java application server widely used in enterprise environments. A path traversal vulnerability in the domain mode implementation allows attackers who have compromised a slave host controller to read arbitrary files on the Domain Controller, potentially exposing sensitive configuration files, keystores, and system credentials.

Technologies: [Red Hat WildFly](https://junglewise.ai/threats/technologies/wildfly). Vendors: [Red Hat](https://junglewise.ai/threats/vendors/red-hat).

## Technical details

The vulnerability exists in the LocalFileRepository.getFile() and getConfigurationFile() methods in wildfly-core/deployment-repository, which fail to validate that resolved file paths remain within configured repository or configuration directories. A remote attacker with the slave host controller secret or who has compromised a slave host controller can supply a crafted relative path containing directory traversal sequences (e.g., ../../etc/passwd) via the slave-DC wire protocol. The Domain Controller will then resolve and serve arbitrary files readable by the DC process. No patch availability information is provided in the advisory.
