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." } ], "source": { "advisory": "GHSA-jfwf-28xr-xw6q", "discovery": "UNKNOWN" } }, "adp": [ { "references": [ { "url": "https://github.com/rclone/rclone/security/advisories/GHSA-jfwf-28xr-xw6q", "tags": [ "exploit" ] } ], "metrics": [ { "other": { "type": "ssvc", "content": { "timestamp": "2026-04-24T00:00:00+00:00", "options": [ { "Exploitation": "poc" }, { "Automatable": "yes" }, { "Technical Impact": "total" } ], "role": "CISA Coordinator", "version": "2.0.3", "id": "CVE-2026-41179" } } } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2026-04-28T03:55:17.599Z" } }, { "affected": [ { "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "cpes": [ "cpe:/a:redhat:openshift_api_data_protection:1" ], "defaultStatus": "unaffected", "packageName": "oadp/oadp-mustgather-rhel9", "product": "OpenShift API for Data Protection", "vendor": "Red Hat" }, { "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "cpes": [ "cpe:/a:redhat:openshift_api_data_protection:1" ], "defaultStatus": "unaffected", "packageName": "oadp/oadp-velero-restic-restore-helper-rhel9", "product": "OpenShift API for Data Protection", "vendor": "Red Hat" }, { "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "cpes": [ "cpe:/a:redhat:openshift_api_data_protection:1" ], "defaultStatus": "unaffected", "packageName": "oadp/oadp-velero-rhel9", "product": "OpenShift API for Data Protection", "vendor": "Red Hat" }, { "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "cpes": [ "cpe:/a:redhat:acm:2" ], "defaultStatus": "unaffected", "packageName": "rhacm2/volsync-rhel9", "product": "Red Hat Advanced Cluster Management for Kubernetes 2", "vendor": "Red Hat" } ], "datePublic": "2026-04-23T00:03:36.282Z", "descriptions": [ { "lang": "en", "value": "A flaw was found in Rclone, a command-line program for syncing files with cloud storage.
