CVE-2026-124079

rConfig Core 8.0.0 before 8.2.19 and rConfig Pro before 8.4.1 RCE via Unauthenticated Redis Queue Poisoning

Published Nov 9, 2026 CVSS 4.0 · 9.3 Critical EPSS < 1% KEV · Not listed
Description
rConfig Core 8.0.0 before 8.2.19 and rConfig Pro before 8.4.1 contain a deserialization of untrusted data vulnerability that allows unauthenticated network attackers to execute arbitrary code by pushing a crafted serialized job onto the Redis-backed Laravel Horizon queue, which runs without authentication in affected deployments. Laravel's CallQueuedHandler unserializes the job without class restrictions, allowing attackers to instantiate the existing App\\Jobs\\TaskDownloadRun class and invoke an attacker-controlled Artisan command. Attackers can leverage the bundled laravel/tinker package to execute arbitrary PHP and operating system commands as the queue worker's user, write a persistent web shell into the web-served storage/app/public directory, and read database credentials, stored device credentials, and API tokens. Where Redis is not directly reachable, authenticated attackers can deliver the payload through the application by configuring a device target that points at the rConfig server's loopback address.
