Prior to 8.5.1, 8.4.4, 8.3.6, 8.2.6, 8.1.6, 8.0.7, and 7.10.13, the POST /api/v1/fingerprint REST endpoint enforces authentication (authRequired: true) but performs no authorization check. Any authenticated user — including a standard user role account — can call this endpoint with {\"setDeploymentAs\": \"new-workspace\"} to permanently deregister the workspace from Rocket.Chat Cloud. This wipes all cloud credentials, removes the workspace license, breaks push notifications for all users, and requires manual re-registration to recover. This vulnerability is fixed in 8.5.1, 8.4.4, 8.3.6, 8.2.6, 8.1.6, 8.0.7, and 7.10.13.","published_at":"2026-06-24T21:08:01.271000Z","last_modified_at":null,"cvss_v3_score":8.1,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H","cvss_v3_severity":"HIGH","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-862"],"nvd_references":["https://github.com/RocketChat/Rocket.Chat/security/advisories/GHSA-8hhc-j325-rxqp"],"vuln_status":null,"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":"2026-06-28T17:55:37.240342Z","updated_at":"2026-06-28T23:30:55.940411Z"},"effective_severity":"HIGH","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"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":"N","value_label":"None"},{"metric":"I","name":"Integrity","value":"H","value_label":"High"},{"metric":"A","name":"Availability","value":"H","value_label":"High"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"rocketchat","vendor_name":"RocketChat","product_slug":"rocket.chat","product_name":"Rocket.Chat","version_start":">= 8.5.0-rc.0, < 8.5.1","version_start_inclusive":true,"version_end":">= 8.5.0-rc.0, < 8.5.1","version_end_inclusive":true,"cpe23_uri":"cve5:rocketchat:rocket.chat:>= 8.5.0-rc.0, < 8.5.1:>= 8.5.0-rc.0, < 8.5.1"},{"vendor_slug":"rocketchat","vendor_name":"RocketChat","product_slug":"rocket.chat","product_name":"Rocket.Chat","version_start":">= 8.4.0-rc.0, < 8.4.4","version_start_inclusive":true,"version_end":">= 8.4.0-rc.0, < 8.4.4","version_end_inclusive":true,"cpe23_uri":"cve5:rocketchat:rocket.chat:>= 8.4.0-rc.0, < 8.4.4:>= 8.4.0-rc.0, < 8.4.4"},{"vendor_slug":"rocketchat","vendor_name":"RocketChat","product_slug":"rocket.chat","product_name":"Rocket.Chat","version_start":">= 8.3.0-rc.0, < 8.3.6","version_start_inclusive":true,"version_end":">= 8.3.0-rc.0, < 8.3.6","version_end_inclusive":true,"cpe23_uri":"cve5:rocketchat:rocket.chat:>= 8.3.0-rc.0, < 8.3.6:>= 8.3.0-rc.0, < 8.3.6"},{"vendor_slug":"rocketchat","vendor_name":"RocketChat","product_slug":"rocket.chat","product_name":"Rocket.Chat","version_start":">= 8.2.0-rc.0, < 8.2.6","version_start_inclusive":true,"version_end":">= 8.2.0-rc.0, < 8.2.6","version_end_inclusive":true,"cpe23_uri":"cve5:rocketchat:rocket.chat:>= 8.2.0-rc.0, < 8.2.6:>= 8.2.0-rc.0, < 8.2.6"},{"vendor_slug":"rocketchat","vendor_name":"RocketChat","product_slug":"rocket.chat","product_name":"Rocket.Chat","version_start":">= 8.1.0-rc.0, < 8.1.6","version_start_inclusive":true,"version_end":">= 8.1.0-rc.0, < 8.1.6","version_end_inclusive":true,"cpe23_uri":"cve5:rocketchat:rocket.chat:>= 8.1.0-rc.0, < 8.1.6:>= 8.1.0-rc.0, < 8.1.6"},{"vendor_slug":"rocketchat","vendor_name":"RocketChat","product_slug":"rocket.chat","product_name":"Rocket.Chat","version_start":">= 7.11.0-rc.0, < 8.0.7","version_start_inclusive":true,"version_end":">= 7.11.0-rc.0, < 8.0.7","version_end_inclusive":true,"cpe23_uri":"cve5:rocketchat:rocket.chat:>= 7.11.0-rc.0, < 8.0.7:>= 7.11.0-rc.0, < 8.0.7"},{"vendor_slug":"rocketchat","vendor_name":"RocketChat","product_slug":"rocket.chat","product_name":"Rocket.Chat","version_start":"< 7.10.13","version_start_inclusive":true,"version_end":"< 7.10.13","version_end_inclusive":true,"cpe23_uri":"cve5:rocketchat:rocket.chat:< 7.10.13:< 7.10.13"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/RocketChat/Rocket.Chat/security/advisories/GHSA-8hhc-j325-rxqp","source_type":"VENDOR_ADVISORY","tags":["advisory"]}],"timeline":[{"type":"published","at":"2026-06-24T21:08:01.271000Z","label":"CVE published","source":null}]}
