CVE-2026-2606— IBM webMethods API Management fails to validate user input and enables unauthorized arbitrary file read

Quick assessment

Affected
IBM webMethods API Gateway (on-prem)
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

IBM webMethods API Gateway是美国国际商业机器（IBM）公司的一个接口网关。 IBM webMethods API Gateway 10.11至10.11_Fix3210.15版本、10.15至10.15_Fix2711.1版本和11.1至11.1_Fix7版本存在路径遍历漏洞，该漏洞源于未能正确验证用户提供给/createapi端点url参数的输入，可能导致攻击者修改参数使用file:// URI方案，从而对底层服务器文件系统进行未经授权的任意文件读取访问。

Vulnerability Description
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.
