{"id":"AZL-91197","summary":"CVE-2026-55655 affecting package openssh 9.8p1-9","details":"A flaw was found in OpenSSH. A local unprivileged attacker on a Linux client host can hijack client-side X11 forwarding connections. This is possible by pre-binding the preferred abstract X socket name when X11 forwarding is enabled and a local UNIX-domain X socket is used. A successful attack can compromise the confidentiality of forwarded X11 traffic, including sensitive window contents and input, and may allow some manipulation of the forwarded session.","modified":"2026-09-02T06:51:55Z","published":"2026-06-23T04:17:40Z","upstream":["CVE-2026-55655"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-55655"}],"affected":[{"package":{"name":"openssh","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/openssh"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"9.8p1-9"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-91197.json"}}],"schema_version":"1.9.0"}
