Wukong_HRM ParamAspect Auth Bypass CVE-2026-108707 Risks Remote HR Data Manipulation and Deletion

Wukong_HRM contains a critical authentication bypass vulnerability within its ParamAspect component, identified as CVE-2026-108707. This flaw allows unauthenticated attackers to access every HRM API endpoint by simply omitting the AUTH-TOKEN header from their requests. The issue grants immediate HR administrator privileges without requiring valid credentials.

Root cause

The vulnerability stems from improper input validation in the ParamAspect module, classified under CWE-287. According to the NVD record, the system fails to enforce authentication checks when the AUTH-TOKEN header is absent. This logical error permits direct access to protected resources. The flaw affects Wukong_HRM versions up to commit 186115e1a5a0b827ad9596ff8c2f3a876fb0cc55.

Attack path

An attacker sends an HTTP request to any HRM API endpoint without including the AUTH-TOKEN header. The ParamAspect component processes this request as valid, granting full administrative access. Attackers can then read sensitive data such as payslips and salary history. They can also download attachments, modify company-wide HR records, or delete employee data entirely.

Affected versions

• WuKongOpenSource Wukong_HRM versions prior to and including commit 186115e1a5a0b827ad9596ff8c2f3a876fb0cc55 are affected.
• The vulnerability is present in the ParamAspect component of these builds.
• No later versions are mentioned in the current advisory as being patched or safe.

Mitigation

• Restrict network access to Wukong_HRM API endpoints using firewalls or web application firewalls.
• Monitor logs for API requests that lack the AUTH-TOKEN header, as this indicates exploitation attempts.
• Ensure strict access controls are applied at the network perimeter to prevent unauthorised external connections.
• Verify that all internal systems interacting with the HRM API enforce additional authentication layers.

What to do and how to stay safe: Wukong_HRM

• Audit firewall rules to block unauthorised external access to HR management API endpoints.
• Monitor server logs for requests missing the AUTH-TOKEN header to detect active exploitation attempts.
• Implement network segmentation to isolate HR systems from general corporate networks.
• Review access controls for all administrative interfaces to ensure secondary verification is required.
