{"id":"PYSEC-2026-3794","details":"openssl_encrypt 1.4.x before 1.4.9 contains an optional D-Bus crypto service whose org.freedesktop.DBus.Properties.Set method performs neither a polkit authorization check nor value validation. Any local user on the system bus can call Set without authorization and set MaxConcurrentOperations (to 0/negative, causing the concurrency gate to refuse all subsequent operations, or to a huge value removing the limit) or the unbounded DefaultTimeout, resulting in a persistent denial of service of the root daemon. The D-Bus service exists only on the 1.4.x line and was removed in 1.5.x.","aliases":["CVE-2026-81686","GHSA-7fhx-8rmv-qjj3"],"modified":"2026-09-03T11:00:03.933864475Z","published":"2026-08-27T17:20:58.257Z","references":[{"type":"ADVISORY","url":"https://github.com/jahlives/openssl_encrypt/security/advisories/GHSA-7fhx-8rmv-qjj3"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/openssl-encrypt-before-1.4.9-d-bus-properties-authorization-bypass"}],"affected":[{"package":{"name":"openssl-encrypt","ecosystem":"PyPI","purl":"pkg:pypi/openssl-encrypt"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.4.9"}]}],"versions":["0.2.2","0.2.3","0.2.4","0.2.5","0.2.6","0.3.0","0.3.1","0.3.2","0.3.3","0.4.0","0.4.1","0.4.2","0.4.3","0.4.4","0.5.0","0.5.1","0.5.3","0.6.0rc1","0.7.0rc2","0.7.1","0.7.2","0.8.0","0.8.1","0.8.2","0.9.2","1.0.0","1.0.1","1.0.2","1.0.3","1.1.0","1.2.0","1.2.1","1.3.0","1.3.1","1.3.2","1.3.3","1.3.4","1.3.5","1.4.0","1.4.0b3","1.4.0b4","1.4.0b5","1.4.0b6","1.4.0b7","1.4.0b8","1.4.1","1.4.1rc2","1.4.2","1.4.4","1.4.5","1.4.6","1.4.7","1.4.8"],"ecosystem_specific":{},"database_specific":{"source":"https://github.com/pypa/advisory-database/blob/main/vulns/openssl-encrypt/PYSEC-2026-3794.yaml"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
