CVE-2026-59732: rclone archive extract allows S3 destination prefix escape via crafted archive paths

MediumCVSS 5.0 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 20/100)

The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
Probability of exploitation in the next 30 days: 0.26% (FIRST EPSS).
Someone with local access to the system can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
Fixed version: rclone rclone 1.74.4.

Low priority for now. Upgrade to rclone rclone 1.74.4 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Rclone is a command-line program to sync files and directories to and from different cloud storage providers. Prior to 1.74.4, rclone archive extract can write extracted files outside the user-selected destination prefix when extracting a crafted archive containing parent path components such as ../, allowing creation or overwrite of sibling objects in the same bucket or path scope. This issue is fixed in version 1.74.4.

Root cause

A user-supplied file name is joined with the allowed directory, but the result is never checked to confirm it is still inside that directory.

The bug in code

The whole CWE-22 class

A representative example of this vulnerability class. Not the vendor's source code; it shows the faulty pattern and its fix.

Vulnerable

Fixed

1const file = path.resolve(ROOT, req.query.name);
