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

- Severity: CVSS 6.5 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fix: a fix or patch is referenced
- Published: 2026-03-03 · Updated: 2026-03-04

## Affected

- IBM webMethods API Gateway (on-prem): from 10.11, through 10.11\_Fix32; from 10.15, through 10.15\_Fix27; from 11.1, through 11.1\_Fix7

## 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.
