CVE-2026-96628— Arcane: Environment access token bypasses the admin-required authorization gate on `/api/debug/pprof`

Quick assessment

Affected
getarcaneapp arcane
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Arcane 是一个用于管理 Docker 容器、镜像、网络和卷的接口。在 2.11.0 版本之前，AuthMiddleware.managerAuth 会接受 X-Arcane-Agent-Token 凭据，而 environment-token 分支在评估 AdminRequired 选项之前就会调用 next。因此，持有有效 X-Arcane-Agent-Token 的攻击者可以通过受 WithAdminRequired 保护的路径请求 /api/debug/pprof/*，因为此时已安装 Environme

Vulnerability Title
Arcane: Environment access token bypasses the admin-required authorization gate on `/api/debug/pprof`
Source: CVE Program / CVE List V5
Vulnerability Description
Arcane is an interface for managing Docker containers, images, networks, and volumes. Prior to 2.11.0, AuthMiddleware.managerAuth accepts X-Arcane-Agent-Token credentials and the environment-token branch calls next before the AdminRequired option is evaluated. An attacker with a valid X-Arcane-Agent-Token can request /api/debug/pprof/* through a route protected by WithAdminRequired because EnvironmentPermissionSet is installed and the request continues without checking IsGlobalAdmin. This exposes administrator-restricted Go pprof runtime and diagnostic information and may impose profiling overhead. This issue is fixed in version 2.11.0.
