Attackers controlling the release distribution path can prepend an unsigned checksum line matching a malicious archive, causing selfupdate to install an attacker-controlled rclone executable.","published":"2026-10-25T14:16:59.120","modified":"2026-10-25T14:16:59.120","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://github.com/rclone/rclone/security/advisories/GHSA-w33h-3qgq-8mv8"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/rclone-1.55.0-before-1.75.2-selfupdate-signature-verification-bypass-via-sha256sums"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-10-25T14:16:59.120"}}
