{"id":"CVE-2026-74886","summary":"openssl_encrypt before 1.4.0 Plugin Import Guard Bypass","details":"openssl_encrypt versions before 1.4.0 contain a plugin sandbox bypass vulnerability where the PluginImportGuard blocks a different set of modules than the AST analyzer's DANGEROUS_MODULES set. Attackers can bypass AST analysis through string obfuscation or encoding to import unblocked dangerous modules like sys, shutil, multiprocessing, importlib, and pickle for arbitrary code execution.","aliases":["GHSA-9pgj-v69p-q586"],"modified":"2026-08-19T03:48:59.530523605Z","published":"2026-08-17T11:04:51.120Z","database_specific":{"cwe_ids":["CWE-184"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/74xxx/CVE-2026-74886.json","cna_assigner":"VulnCheck"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/74xxx/CVE-2026-74886.json"},{"type":"ADVISORY","url":"https://github.com/jahlives/openssl_encrypt/security/advisories/GHSA-9pgj-v69p-q586"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-74886"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/openssl-encrypt-before-plugin-import-guard-bypass"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/jahlives/openssl_encrypt","events":[{"introduced":"0"},{"fixed":"768df5cd1910e349509f07a27eeac6951e0003bf"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"1.4.0"}],"source":["AFFECTED_FIELD","DESCRIPTION"]}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-74886.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
