## Summary

- **CVE ID:** CVE-2026-79783
- **Severity:** LOW
- **CVSS Score:** 3.6 (CVSS:4.0/AV:L/AC:H/AT:P/PR:N/UI:P/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N)
- **CWE:** CWE-732
- **Published:** Aug 25, 2026
- **Last Modified:** Aug 25, 2026

## Description

rclone before 1.74.4 fails to mask special permission bits when applying source-supplied mode metadata in the local backend, allowing attackers to set setuid/setgid bits on attacker-controlled files. When copying with metadata preservation from an untrusted remote, attackers can plant a setuid binary that escalates privileges to root if rclone runs as root, or to the service account user otherwise.

## Affected Products

- rclone — rclone (0)
- rclone — rclone (1.74.4)
