Summary

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.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
