Prior to 1.20.6, a Stored Cross-Site Scripting (XSS) vulnerability exists in the BlockNote editor component. Due to a lack of protocol validation in the FileBlock component and insufficient server-side inspection of block content, an attacker can inject a javascript: URI into the url property of a file block. This allows the execution of arbitrary JavaScript when a user clicks on the malicious file attachment. This vulnerability is fixed in 1.20.6.","published_at":"2026-04-21T16:22:30.378000Z","last_modified_at":null,"cvss_v3_score":5.7,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:N/A:N","cvss_v3_severity":"MEDIUM","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-79"],"nvd_references":["https://github.com/twentyhq/twenty/security/advisories/GHSA-7w89-7q26-gj7q","https://github.com/twentyhq/twenty/commit/8da69e0f77ea820a6845a4c3c025b6af3861d523"],"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":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-28T23:30:03.101844Z"},"effective_severity":"MEDIUM","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":"R","value_label":"Required"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"H","value_label":"High"},{"metric":"I","name":"Integrity","value":"N","value_label":"None"},{"metric":"A","name":"Availability","value":"N","value_label":"None"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"twentyhq","vendor_name":"twentyhq","product_slug":"twenty","product_name":"twenty","version_start":"< 1.20.6","version_start_inclusive":true,"version_end":"< 1.20.6","version_end_inclusive":true,"cpe23_uri":"cve5:twentyhq:twenty:< 1.20.6:< 1.20.6"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/twentyhq/twenty/security/advisories/GHSA-7w89-7q26-gj7q","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/twentyhq/twenty/commit/8da69e0f77ea820a6845a4c3c025b6af3861d523","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2026-04-21T16:22:30.378000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:53:30.970244Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:53:30.970244Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:53:30.970244Z","label":"CVSS score revised","source":"cvelistv5"}]}
