{"id":"CVE-2026-48114","summary":"Metacat has an unauthenticated SQL injection vulnerability","details":"Metacat is data repository software that helps researchers preserve, share, and discover data. 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.","aliases":["GHSA-wrc6-rc34-hrcg"],"modified":"2026-07-08T08:11:48.828682377Z","published":"2026-06-15T18:52:41.466Z","database_specific":{"cna_assigner":"GitHub_M","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/48xxx/CVE-2026-48114.json","cwe_ids":["CWE-287","CWE-89"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/48xxx/CVE-2026-48114.json"},{"type":"ADVISORY","url":"https://github.com/NCEAS/metacat/security/advisories/GHSA-wrc6-rc34-hrcg"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-48114"},{"type":"FIX","url":"https://github.com/NCEAS/metacat/commit/820d595309b399fdbdf4983bd1b1dd795773472a"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/nceas/metacat","events":[{"introduced":"a2e008f91e042c3eda9caa1bf28b296f3bab5fa6"},{"fixed":"820d595309b399fdbdf4983bd1b1dd795773472a"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"2.0.0"},{"fixed":"3.0.0"}]}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-48114.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
