CVE-2026-10050
Description
A flaw was found in Eclipse Jetty, a widely used web server and servlet container. This vulnerability affects its HTTP Digest authentication mechanism, which is used to verify user identities. The issue arises because Jetty's hash computation for passwords does not correctly handle certain characters, leading to a weakness in how passwords are processed. A remote attacker could exploit this by crafting a specific password that generates the same internal hash as a legitimate user's password, thereby bypassing authentication and gaining unauthorized access to the victim's account.
Statement
Important: This flaw allows an authentication bypass in Eclipse Jetty's HTTP Digest authentication. An attacker who knows a victim's username can craft a collision password if the original password contains non-Latin-1 characters, leading to unauthorized access in affected Red Hat products that utilize this authentication method.
Mitigation
To mitigate this vulnerability, ensure that all user passwords configured for HTTP Digest authentication in affected Eclipse Jetty deployments exclusively use characters within the Latin-1 character set. This prevents the character encoding collision that leads to authentication bypass.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
