Weaknesses

  • CWE-918: CWE-918 Server-Side Request Forgery (SSRF)

Workarounds

Workarounds/Mitigation guidance:

No complete workaround exists without upgrading. As a partial mitigation, restrict tool-creation

permissions (tools.create) to fully trusted users only, limiting the pool of accounts that could

stage a registration with a controlled hostname. This does not eliminate the vulnerability but

reduces exposure in environments where least-privilege access controls are enforced.

IBM strongly recommends upgrading to v1.0.7 or higher.
