A SQL injection vulnerability exists in some types implementing ILiteralType.ObjectToSQLString. Callers of these methods are exposed to the vulnerability, which includes mappings using inheritance with discriminator values; HQL queries referencing a static field of the application; users of the SqlInsertBuilder and SqlUpdateBuilder utilities, calling their AddColumn overload taking a literal value; and any direct use of the ObjectToSQLString methods for building SQL queries on the user side. This vulnerability is fixed in 5.4.9 and 5.5.2.","published":"2024-07-08T14:52:39.053Z","modified":"2026-08-12T03:51:28.642133170Z","cvss":{"score":5.9,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"NuGet","name":"NHibernate","fixedVersion":"5.4.9"},{"ecosystem":"NuGet","name":"NHibernate","fixedVersion":"5.5.2"}],"fix":{"url":"https://github.com/nhibernate/nhibernate-core/commit/b4a69d1a5ff5744312478d70308329af496e4ba9","label":"nhibernate/nhibernate-core@b4a69d1"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/39xxx/CVE-2024-39677.json"},{"type":"ADVISORY","url":"https://github.com/nhibernate/nhibernate-core/security/advisories/GHSA-fg4q-ccq8-3r5q"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-39677"},{"type":"REPORT","url":"https://github.com/nhibernate/nhibernate-core/issues/3516"},{"type":"FIX","url":"https://github.com/nhibernate/nhibernate-core/commit/b4a69d1a5ff5744312478d70308329af496e4ba9"},{"type":"FIX","url":"https://github.com/nhibernate/nhibernate-core/pull/3517"},{"type":"FIX","url":"https://github.com/nhibernate/nhibernate-core/pull/3547"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:28.642133170Z"}}
