An attacker who successfully exploited the vulnerability could read privileged data from the enclave heap across trust boundaries. To exploit this vulnerability, an attacker would have to log on to an affected system and run a specially crafted application. The vulnerability would not allow an attacker to elevate user rights directly, but it could be used to obtain information otherwise considered confidential in an enclave, which could be used in further compromises. The issue has been addressed in version 0.12.0 and the current master branch. Users will need to to recompile their applications against the patched libraries to be protected from this vulnerability.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N","score":6.8},"cwes":["CWE-552"],"references":["https://github.com/openenclave/openenclave/blob/master/CHANGELOG.md#v0120","https://github.com/openenclave/openenclave/commit/bcac8e7acb514429fee9e0b5d0c7a0308fd4d76b","https://github.com/openenclave/openenclave/security/advisories/GHSA-525h-wxcc-f66m","https://github.com/openenclave/openenclave/blob/master/CHANGELOG.md#v0120","https://github.com/openenclave/openenclave/commit/bcac8e7acb514429fee9e0b5d0c7a0308fd4d76b"],"products":["openenclave:openenclave"],"source":"nvd","synced_at":"2026-10-19T21:09:53.489947993+00:00"},"epss":{"cve":"CVE-2020-15224","score":0.00635,"percentile":0.50459,"date":"2026-10-31"},"kev":null,"osv":[],"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).
