Attackers can place a symlink at a predictable --files-from or --password-file path, or supply a --files-from path that escapes the daemon module root, to read arbitrary files accessible to the rsync process.","published_at":"2026-08-13T14:32:26.170000Z","last_modified_at":"2026-08-26T17:00:56.943000Z","cvss_v3_score":7.1,"cvss_v3_vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","cvss_v3_severity":"HIGH","cvss_v4_score":8.4,"cvss_v4_vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","cvss_v4_severity":"HIGH","ssvc_decision":null,"ssvc_exploitation":"none","ssvc_automatable":false,"ssvc_technical_impact":"total","cwes":["CWE-61"],"nvd_references":["https://github.com/RsyncProject/rsync/security/advisories/GHSA-4mfr-8jrv-49x4","https://github.com/RsyncProject/rsync/releases/tag/v3.5.0","https://www.vulncheck.com/advisories/rsync-arbitrary-file-read-via-symlink-following"],"vuln_status":"Undergoing Analysis","trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-08-13T16:21:52.865932Z","updated_at":"2026-08-27T17:38:41.369924Z"},"effective_severity":"HIGH","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"L","value_label":"Local"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"L","value_label":"Low"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"H","value_label":"High"},{"metric":"I","name":"Integrity","value":"H","value_label":"High"},{"metric":"A","name":"Availability","value":"N","value_label":"None"}]},"cvss_v4_decoded":{"version":"4.0","metrics":[{"metric":"AV","name":"Attack Vector","value":"L","value_label":"Local"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"AT","name":"Attack Requirements","value":"N","value_label":"None"},{"metric":"PR","name":"Privileges Required","value":"L","value_label":"Low"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"VC","name":"Confidentiality (Vulnerable System)","value":"H","value_label":"High"},{"metric":"VI","name":"Integrity (Vulnerable System)","value":"H","value_label":"High"},{"metric":"VA","name":"Availability (Vulnerable System)","value":"N","value_label":"None"},{"metric":"SC","name":"Confidentiality (Subsequent System)","value":"N","value_label":"None"},{"metric":"SI","name":"Integrity (Subsequent System)","value":"N","value_label":"None"},{"metric":"SA","name":"Availability (Subsequent System)","value":"N","value_label":"None"}]},"affected":[{"vendor_slug":"rsyncproject","vendor_name":"RsyncProject","product_slug":"rsync","product_name":"rsync","version_start":"0","version_start_inclusive":true,"version_end":"3.4.4","version_end_inclusive":true,"cpe23_uri":"cve5:rsyncproject:rsync:0:3.4.4"},{"vendor_slug":"rsyncproject","vendor_name":"RsyncProject","product_slug":"rsync","product_name":"rsync","version_start":"3.5.0","version_start_inclusive":true,"version_end":"3.5.0","version_end_inclusive":true,"cpe23_uri":"cve5:rsyncproject:rsync:3.5.0:3.5.0"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/RsyncProject/rsync/security/advisories/GHSA-4mfr-8jrv-49x4","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/RsyncProject/rsync/releases/tag/v3.5.0","source_type":"PATCH","tags":["patch"]},{"url":"https://www.vulncheck.com/advisories/rsync-arbitrary-file-read-via-symlink-following","source_type":"VENDOR_ADVISORY","tags":["advisory"]}],"timeline":[{"type":"published","at":"2026-08-13T14:32:26.170000Z","label":"CVE published","source":null}]}
