Detailsinfo

A vulnerability classified as critical was found in getarcaneapp Arcane up to 2.10.x. This vulnerability affects the function AuthMiddleware.managerAuth of the file /api/debug/pprof/* of the component Authentication Middleware. The manipulation of the argument X-Arcane-Agent-Token with an unknown input leads to a improper authentication vulnerability. The CWE definition for the vulnerability is CWE-287. When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

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.

The advisory is shared for download at github.com. This vulnerability was named CVE-2026-96628 since 09/23/2026. The exploitation appears to be easy. The attack can be initiated remotely. There are known technical details, but no exploit is available.
