Prior to 3.20.1780-lts, the authenticated endpoint POST /api/data-sources/decrypt returns the decrypted plaintext for any credential whose credential_id is supplied in the request body. Unlike every neighbouring data-source route, this handler is not protected by ValidateDataSourceGuard, does not receive the calling @User(), and the underlying CredentialsService.getValue() looks the credential up by id only, with no organization scoping. As a result, any authenticated user of any organization can decrypt the data-source secrets of any other organization by supplying that organization's credential_id — a cross-tenant confidentiality breach. This vulnerability is fixed in 3.20.1780-lts.","published_at":"2026-06-25T16:08:14.766000Z","last_modified_at":null,"cvss_v3_score":6.8,"cvss_v3_vector":"CVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:C/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-639","CWE-863"],"nvd_references":["https://github.com/ToolJet/ToolJet/security/advisories/GHSA-x7qj-hfg8-p4cw"],"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":"MEDIUM","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"A","value_label":"Adjacent"},{"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":"C","value_label":"Changed"},{"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":"tooljet","vendor_name":"ToolJet","product_slug":"tooljet","product_name":"ToolJet","version_start":"< 3.20.1780-lts","version_start_inclusive":true,"version_end":"< 3.20.1780-lts","version_end_inclusive":true,"cpe23_uri":"cve5:tooljet:tooljet:< 3.20.1780-lts:< 3.20.1780-lts"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/ToolJet/ToolJet/security/advisories/GHSA-x7qj-hfg8-p4cw","source_type":"VENDOR_ADVISORY","tags":["advisory"]}],"timeline":[{"type":"published","at":"2026-06-25T16:08:14.766000Z","label":"CVE published","source":null}]}
