Rclone is a command-line program to sync files and directories to and from different cloud storage providers. Prior to 1.74.4, rclone serve restic --private-repos enforces authorization using the routed user path segment while building the backend object key from the raw uncleaned URL path, allowing an authenticated user to include .. in a request such as //..//config and read, overwrite, or delete another user's private repository on backends that clean path components. This issue is fixed in version 1.74.4.

    (CVE-2026-59733)

The remote Fedora 45 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2026-612edb2029 advisory.

    Update to 1.75.0


Tenable has extracted the preceding description block directly from the Fedora security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-2002 advisory.

    Rclone is a command-line program to sync files and directories to and from different cloud storage     providers. Prior to 1.74.4, with -l/--links, rclone serializes symlinks as .rclonelink text objects and     recreates them on a local destination without validating the target, allowing an attacker-controlled     remote to plant an escaping symlink and cause a following object write to land outside the destination     with attacker-chosen contents. This issue is fixed in version 1.74.4. (CVE-2026-54572)
