GHSA-P85C-J652-88PJ

Vulnerability from github – Published: 2026-09-11 15:32 – Updated: 2026-09-11 15:32

Details

The XSLT Transformer Step builds a bare TransformerFactory without the proper security options set, so XXE injection can allow data exfiltration and denial-of-service attacks.

Severity

8.2 (High)


                  
                    CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:L

Detection rules are retrieved from Rulezet.

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.
