{"id":"CVE-2026-81686","summary":"openssl_encrypt before 1.4.9 D-Bus Properties Authorization Bypass","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":["GHSA-7fhx-8rmv-qjj3"],"modified":"2026-08-30T03:30:40.813156723Z","published":"2026-08-27T14:50:51.068Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-20"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/81xxx/CVE-2026-81686.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/81xxx/CVE-2026-81686.json"},{"type":"ADVISORY","url":"https://github.com/jahlives/openssl_encrypt/security/advisories/GHSA-7fhx-8rmv-qjj3"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-81686"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/openssl-encrypt-before-1.4.9-d-bus-properties-authorization-bypass"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/jahlives/openssl_encrypt","events":[{"introduced":"768df5cd1910e349509f07a27eeac6951e0003bf"},{"fixed":"39b0a010cae90520f74b7194f61fedd43af04ef8"}],"database_specific":{"source":["AFFECTED_FIELD","DESCRIPTION"],"extracted_events":[{"introduced":"0"},{"fixed":"1.4.9"},{"introduced":"1.4.x"}]}}],"versions":["v1.4.7","v1.4.6","v1.4.5","v1.4.4","v1.4.2","v1.4.1rc2","v1.4.1rc1","v1.4.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-81686.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N"}]}
