Starting in version 1.48.0 and prior to version 1.73.5, the RC endpoint `operations/fsinfo` is exposed without `AuthRequired: true` and accepts attacker-controlled `fs` input. Because `rc.GetFs(...)` supports inline backend definitions, an unauthenticated attacker can instantiate an attacker-controlled backend on demand. For the WebDAV backend, `bearer_token_command` is executed during backend initialization, making single-request unauthenticated local command execution possible on reachable RC deployments without global HTTP authentication. Version 1.73.5 patches the issue.","affected":[{"package":{"name":"rclone","ecosystem":"Bitnami","purl":"pkg:bitnami/rclone"},"ranges":[{"type":"SEMVER","events":[{"introduced":"1.48.0"},{"fixed":"1.73.5"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/rclone/BIT-rclone-2026-41179.json"},"severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}],"references":[{"type":"WEB","url":"https://github.com/rclone/rclone/blob/bf55d5e6d37fd86164a87782191f9e1ffcaafa82/backend/webdav/webdav.go"},{"type":"WEB","url":"https://github.com/rclone/rclone/blob/bf55d5e6d37fd86164a87782191f9e1ffcaafa82/fs/operations/rc.go"},{"type":"WEB","url":"https://github.com/rclone/rclone/blob/bf55d5e6d37fd86164a87782191f9e1ffcaafa82/fs/rc/cache.go"},{"type":"ADVISORY","url":"https://github.com/rclone/rclone/security/advisories/GHSA-jfwf-28xr-xw6q"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-41179"},{"type":"WEB","url":"https://github.com/rclone/rclone/commit/2a9e952b38e03a96bf40c9eb6e8e22199865ee3b"},{"type":"WEB","url":"https://github.com/rclone/rclone/releases/tag/v1.73.5"},{"type":"WEB","url":"https://rclone.org/changelog/#v1-73-5-2026-04-19"},{"type":"WEB","url":"https://access.redhat.com/security/cve/CVE-2026-41179"},{"type":"WEB","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2460988"},{"type":"WEB","url":"https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-41179.json"}],"database_specific":{"cpes":["cpe:2.3:a:rclone:rclone:*:*:*:*:*:go:*:*"],"severity":"Critical"}}
