{"id":"CVE-2022-31139","summary":"No security checking for UnsafeAccess.getInstance() in UnsafeAccessor","details":"UnsafeAccessor (UA) is a bridge to access jdk.internal.misc.Unsafe & sun.misc.Unsafe. Normally, if UA is loaded as a named module, the internal data of UA is protected by JVM and others can only access UA via UA's standard API. The main application can set up `SecurityCheck.AccessLimiter` for UA to limit access to UA. Starting with version 1.4.0 and prior to version 1.7.0, when `SecurityCheck.AccessLimiter` is set up, untrusted code can access UA without limitation, even when UA is loaded as a named module. This issue does not affect those for whom `SecurityCheck.AccessLimiter` is not set up. Version 1.7.0 contains a patch.","aliases":["GHSA-cr6p-23cf-w9g9"],"modified":"2026-04-10T04:47:55.793998Z","published":"2022-07-11T18:25:11Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/31xxx/CVE-2022-31139.json","cwe_ids":["CWE-200"],"cna_assigner":"GitHub_M"},"references":[{"type":"WEB","url":"https://github.com/Karlatemp/UnsafeAccessor/releases/tag/1.7.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/31xxx/CVE-2022-31139.json"},{"type":"ADVISORY","url":"https://github.com/Karlatemp/UnsafeAccessor/security/advisories/GHSA-cr6p-23cf-w9g9"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-31139"},{"type":"FIX","url":"https://github.com/Karlatemp/UnsafeAccessor/commit/4ef83000184e8f13239a1ea2847ee401d81585fd"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/karlamoe/unsafe-accessor","events":[{"introduced":"0"},{"fixed":"4ef83000184e8f13239a1ea2847ee401d81585fd"},{"fixed":"de5d97c6eb5f6af5df929bb02a1ccce3849628fe"}]}],"versions":["1.2.2","1.4.0","1.6.0","1.6.1","1.6.2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-31139.json"}},{"ranges":[{"type":"GIT","repo":"https://github.com/karlatemp/unsafeaccessor","events":[{"introduced":"42a3ec0012ee32af040ec0c83d32ff03b5b72a89"},{"fixed":"de5d97c6eb5f6af5df929bb02a1ccce3849628fe"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-31139.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}
