{"id":"CVE-2026-48114","state":"PUBLISHED","title":"Metacat has an unauthenticated SQL injection vulnerability","description":"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.","publishedAt":"2026-06-15T18:52:41.466Z","updatedAt":"2026-06-15T22:07:41.397Z","severity":{"score":9.8,"label":"Critical","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["NCEAS metacat"],"affected":[{"vendor":"NCEAS","product":"metacat","versions":[{"version":">= 2.0.0, < 3.0.0","status":"affected"}]}],"references":["https://github.com/NCEAS/metacat/security/advisories/GHSA-wrc6-rc34-hrcg","https://github.com/NCEAS/metacat/commit/820d595309b399fdbdf4983bd1b1dd795773472a"],"weaknesses":["CWE-89","CWE-287"],"ingestedAt":"2026-10-29T20:12:07.131Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/48xxx/CVE-2026-48114.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-48114","state":"PUBLISHED","datePublished":"2026-06-15T18:52:41.466Z","dateUpdated":"2026-06-15T22:07:41.397Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-05-20T18:46:58.289Z"},"containers":{"cna":{"title":"Metacat has an unauthenticated SQL injection vulnerability","descriptions":[{"lang":"en","value":"Metacat is data repository software that helps researchers preserve, share, and discover data.
