CVE-2026-59732
Description
A flaw was found in rclone, a command-line program for managing cloud storage. An attacker could craft a malicious archive that, when extracted by a user, allows files to be written outside the intended destination directory. This path traversal vulnerability could lead to the creation or overwrite of other files within the same storage location, potentially compromising data integrity.
Statement
Red Hat ships rclone in the VolSync component of Red Hat Advanced Cluster Management for Kubernetes (RHACM). All shipped versions are affected by this path traversal vulnerability in rclone's archive extraction functionality. Exploitation requires a user to actively run rclone archive extract on an attacker-supplied malicious archive.
Mitigation
Do not use `rclone archive extract` to extract archives from untrusted or unverified sources. If archive extraction is required, inspect the archive contents first using `rclone archive list` to check for suspicious path components (e.g., `../`).
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.

Understanding the Weakness (CWE)
Integrity,Confidentiality,Availability
Technical Impact: Execute Unauthorized Code or Commands
The attacker may be able to create or overwrite critical files that are used to execute code, such as programs or libraries.
Integrity
Technical Impact: Modify Files or Directories
The attacker may be able to overwrite or create critical files, such as programs, libraries, or important data. If the targeted file is used for a security mechanism, then the attacker may be able to bypass that mechanism. For example, appending a new account at the end of a password file may allow an attacker to bypass authentication.
Confidentiality
Technical Impact: Read Files or Directories
The attacker may be able read the contents of unexpected files and expose sensitive data. If the targeted file is used for a security mechanism, then the attacker may be able to bypass that mechanism. For example, by reading a password file, the attacker could conduct brute force password guessing attacks in order to break into an account on the system.
Availability
Technical Impact: DoS: Crash, Exit, or Restart
The attacker may be able to overwrite, delete, or corrupt unexpected critical files such as programs, libraries, or important data. This may prevent the product from working at all and in the case of protection mechanisms such as authentication, it has the potential to lock out product users.
