CVE-2026-2606 — Ibm Webmethods Api Gateway security vulnerability

Medium CVSS 6.5

IBM webMethods API Gateway (on-prem) 10.11 through 10.11_Fix3210.15 to 10.15_Fix2711.1 to 11.1_Fix7 IBM webMethods API Management (on-prem) fails to properly validate user-supplied input passed to the url parameter on the /createapi endpoint. An attacker can modify this parameter to use a file:// URI schema instead of the expected https:// schema, enabling unauthorized arbitrary file read access on the underlying server file system.

Path traversal, unsafe upload, and file handling

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace untrusted filenames, archive entries, URLs, and path segments into read, write, include, extraction, and upload operations.
  • Identify filesystem roots, mount permissions, symbolic-link behavior, archive handling, and whether uploaded content is web-accessible or executable.
  • Review canonicalization and containment checks across supported operating systems and storage backends.

Remediate safely

  • Generate server-side storage identifiers and resolve paths beneath a fixed root using filesystem-aware containment checks.
  • Reject absolute, parent-relative, alternate-separator, device, link, and archive entries that escape the intended root.
  • Store uploads outside executable or served paths, validate type and size, and use private atomic temporary files.
