Vulnerability from cvelistv5 – Published: 2026-03-03 19:38 – Updated: 2026-03-04 21:11

Title

IBM webMethods API Management fails to validate user input and enables unauthorized arbitrary file read

Summary

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.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
