Attackers can inject shell metacharacters or newline characters into unsanitized user-supplied values such as hostnames and hostspecs to execute arbitrary commands under the privileges of the rsync process or the invoking user.","modified":"2026-08-31T05:26:27Z","published":"2026-08-13T15:19:43Z","upstream":["CVE-2026-53790"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53790"}],"affected":[{"package":{"name":"rsync","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/rsync"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.5.0-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-95834.json"}}],"schema_version":"1.9.0"}
