CVE-2026-110008
개요
A flaw was found in @fastify/oauth2. Due to inconsistent cookie path handling during the authentication process, temporary verification cookies are not properly removed after the login flow completes. As a result, single-use authentication tokens persist throughout the user's browser session. A remote attacker can exploit this condition to execute a login Cross-Site Request Forgery (CSRF) attack, forcing a victim's browser to authenticate into an attacker-controlled account.
내용
This vulnerability is rated as Moderate severity because exploitation requires user interaction and specific prerequisites to conduct cross-site request forgery during login, without granting arbitrary code execution or direct access to victim credentials. Within Red Hat OpenShift Dev Spaces, the affected library is utilized internally by the dashboard component to handle OAuth authentication workflows. The blast radius is constrained because an attacker can only force a victim to authenticate into an external account under attacker control, rather than hijacking existing user sessions or modifying cluster resources.
완화 방법
Upgrade @fastify/oauth2 to 8.3.2 in devspaces/dashboard-rhel9, or apply upstream workaround (explicit cookie path 'cookie:{path:"/"}', hostPrefixedCookies:true, or single-segment startRedirectPath).
CVSS (Common Vulnerability Scoring System) 점수 세부 사항
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).

It is possible to overflow the number of temporary files because directories typically have limits on the number of files allowed. This could create a denial of service problem.
