When Default Typing is enabled (either globally or for a specific property) for an externally exposed JSON endpoint, the service has the mysql-connector-java jar (8.0.14 or earlier) in the classpath, and an attacker can host a crafted MySQL server reachable by the victim, an attacker can send a crafted JSON message that allows them to read arbitrary local files on the server. This occurs because of missing com.mysql.cj.jdbc.admin.MiniAdmin validation.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-502"],"references":["http://russiansecurity.expert/2016/04/20/mysql-connect-file-read/","http://www.securityfocus.com/bid/109227","https://access.redhat.com/errata/RHSA-2019:2858","https://access.redhat.com/errata/RHSA-2019:2935","https://access.redhat.com/errata/RHSA-2019:2936"],"products":["debian:debian_linux","fasterxml:jackson-databind"],"source":"nvd","synced_at":"2026-10-19T20:56:19.218283075+00:00"},"epss":{"cve":"CVE-2019-12086","score":0.21949,"percentile":0.97638,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-5ww9-j83m-q7qx","url":"https://osv.dev/vulnerability/GHSA-5ww9-j83m-q7qx","summary":"Information exposure in FasterXML jackson-databind","modified":"2024-03-15T01:17:50.016820Z","packages":[{"ecosystem":"Maven","name":"com.fasterxml.jackson.core:jackson-databind","purl":"pkg:maven/com.fasterxml.jackson.core/jackson-databind","ranges":[">=2.9.0 <2.9.9"],"fixed":["2.9.9"]},{"ecosystem":"Maven","name":"com.fasterxml.jackson.core:jackson-databind","purl":"pkg:maven/com.fasterxml.jackson.core/jackson-databind","ranges":[">=2.8.0 <2.8.11.4"],"fixed":["2.8.11.4"]},{"ecosystem":"Maven","name":"com.fasterxml.jackson.core:jackson-databind","purl":"pkg:maven/com.fasterxml.jackson.core/jackson-databind","ranges":[">=2.7.0 <2.7.9.6"],"fixed":["2.7.9.6"]},{"ecosystem":"Maven","name":"com.fasterxml.jackson.core:jackson-databind","purl":"pkg:maven/com.fasterxml.jackson.core/jackson-databind","ranges":[">=2.0.0 <2.6.7.3"],"fixed":["2.6.7.3"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
