Rclone is a command-line program to sync files and directories to and from different cloud storage providers. From 1.46.0 until 1.74.3, rclone rcd --rc-serve accepts unauthenticated GET and HEAD requests to paths of the form: /[remote:path]/object. The remote value is parsed from the URL and passed to normal backend initialization. Inline remote configuration can set backend options that execute local commands during initialization. As a result, a single unauthenticated GET or HEAD request can execute a command as the rclone process user. This vulnerability is fixed in 1.74.3.

A flaw was found in Rclone, a command-line program for cloud storage synchronization. When the `rcd --rc-serve` option is enabled, an unauthenticated remote attacker can send specially crafted GET or HEAD requests to execute arbitrary commands as the Rclone process user. This vulnerability allows for remote code execution, potentially compromising the system where Rclone is running.

OpenShift API for Data Protection (OADP) and Red Hat Advanced Cluster Management for Kubernetes (RHACM) do not run rclone rcd --rc-serve with an unauthenticated RC listener. OADP relies on Restic (rclone serve restic --stdio) and Kopia (WebDAV serve with RC authentication), while RHACM VolSync uses rclone sync/copy or only compile-time dependencies. Until upgraded: 1. Stop using --rc-serve 2. Add RC auth (--rc-user + --rc-pass or --rc-htpasswd), and 3. Keep RC on localhost only (do not bind 0.0.0.0 without auth) Cryostat 4 Not affected cryostat/cryostat-storage-rhel9 OpenShift API for Data Protection Not affected oadp/oadp-mustgather-rhel9 OpenShift API for Data Protection Not affected oadp/oadp-velero-restic-restore-helper-rhel9 OpenShift API for Data Protection Not affected oadp/oadp-velero-rhel9 Red Hat Advanced Cluster Management for Kubernetes 2 Not affected rhacm2/volsync-operator-bundle Red Hat Advanced Cluster Management for Kubernetes 2 Not affected rhacm2/volsync-rhel9 https://www.cve.org/CVERecord?id=CVE-2026-49980 https://nvd.nist.gov/vuln/detail/CVE-2026-49980 https://github.com/rclone/rclone/security/advisories/GHSA-qw24-gh76-8rvv
