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." } ] }, "impact": { "cvss": { "attackComplexity": "HIGH", "attackVector": "NETWORK", "availabilityImpact": "NONE", "baseScore": 5.9, "baseSeverity": "MEDIUM", "confidentialityImpact": "HIGH", "integrityImpact": "NONE", "privilegesRequired": "NONE", "scope": "UNCHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N", "version": "3.1" } }, "problemtype": { "problemtype_data": [ { "description": [ { "lang": "eng", "value": "CWE-200: Exposure of Sensitive Information to an Unauthorized Actor" } ] } ] }, "references": { "reference_data": [ { "name": "https://github.com/Karlatemp/UnsafeAccessor/security/advisories/GHSA-cr6p-23cf-w9g9", "refsource": "CONFIRM", "url": "https://github.com/Karlatemp/UnsafeAccessor/security/advisories/GHSA-cr6p-23cf-w9g9" }, { "name": "https://github.com/Karlatemp/UnsafeAccessor/commit/4ef83000184e8f13239a1ea2847ee401d81585fd", "refsource": "MISC", "url": "https://github.com/Karlatemp/UnsafeAccessor/commit/4ef83000184e8f13239a1ea2847ee401d81585fd" }, { "name": "https://github.com/Karlatemp/UnsafeAccessor/releases/tag/1.7.0", "refsource": "MISC", "url": "https://github.com/Karlatemp/UnsafeAccessor/releases/tag/1.7.0" } ] }, "source": { "advisory": "GHSA-cr6p-23cf-w9g9", "discovery": "UNKNOWN" } }
