Vulnerability from github – Published: 2026-10-15 09:30 – Updated: 2026-10-15 09:30

Details

In Eclipse Jetty, HttpClient may receive a redirect of the form:




/secure/../evil

If an attacker is able to control the redirects, then HttpClient matches authentication credentials against /secure rather than normalizing the path to /evil, and will therefore follow the redirect sending the Authorization header for /secure to /evil.

This also mean that the attacker must have an evil application deployed on the same domain as the target.

Severity

8.2 (High)

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.
