Versions 2.0.0 and and above contain an unauthenticated SQL injection in the /harvesterRegistration endpoint. HarvesterRegistration.dbInsert() builds an INSERT against HARVEST_SITE_SCHEDULE via string concatenation, using a quoteString() helper that performs raw single-quote wrapping without escaping. Three request parameters reach the sink: unit, contactEmail, and documentListURL. The servlet does not verify a real LDAP identity. Allowing the vulnerable insert to proceed. Since the PostgreSQL backend permits stacked queries via Statement.executeUpdate(), this vulnerability allows full read/write/execute access in the Metacat database context. The vulnerability was remediated in Metacat 3.0.0.","published_at":"2026-06-15T18:52:41.466000Z","last_modified_at":null,"cvss_v3_score":9.8,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","cvss_v3_severity":"CRITICAL","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-89","CWE-287"],"nvd_references":["https://github.com/NCEAS/metacat/security/advisories/GHSA-wrc6-rc34-hrcg","https://github.com/NCEAS/metacat/commit/820d595309b399fdbdf4983bd1b1dd795773472a"],"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":"2026-06-28T23:30:42.802049Z"},"effective_severity":"CRITICAL","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":"N","value_label":"None"},{"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":"H","value_label":"High"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"nceas","vendor_name":"NCEAS","product_slug":"metacat","product_name":"metacat","version_start":">= 2.0.0, < 3.0.0","version_start_inclusive":true,"version_end":">= 2.0.0, < 3.0.0","version_end_inclusive":true,"cpe23_uri":"cve5:nceas:metacat:>= 2.0.0, < 3.0.0:>= 2.0.0, < 3.0.0"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/NCEAS/metacat/security/advisories/GHSA-wrc6-rc34-hrcg","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/NCEAS/metacat/commit/820d595309b399fdbdf4983bd1b1dd795773472a","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2026-06-15T18:52:41.466000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:55:03.830140Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:55:03.830140Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:55:03.830140Z","label":"CVSS score revised","source":"cvelistv5"}]}
