What is CVE-2026-107151?
CVE-2026-107151 is a medium-severity missing authorization vulnerability in Red Hat Satellite 6, published on 7 Oct 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
Missing authentication has been found in remote-execution task updates in the smart_proxy_dynflow package. The progress and completion callbacks accept a report when the one-time token is missing. A network attacker or user must already know the identifier of a running job. This applies when remote execution is set to pull or pull-mqtt mode. They can send their own job output and mark the job as a success or a failure. The job is then recorded with that result.
Weakness: CWE-306
