{"id":"AZL-95795","summary":"CVE-2026-70452 affecting package rsync 3.4.3-1","details":"rsync 3.1.0 before 3.5.0 contains an access control bypass vulnerability that allows remote attackers to circumvent hosts deny rules by inducing DNS resolution failures during hostname-based access control evaluation. When a DNS lookup for a hostname-based deny rule fails, the daemon skips the rule rather than defaulting to a deny decision, enabling attackers who can trigger DNS failures to bypass module-level IP access controls and gain unauthorized access to restricted module file trees.","modified":"2026-08-30T05:26:50Z","published":"2026-08-13T15:19:58Z","upstream":["CVE-2026-70452"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-70452"}],"affected":[{"package":{"name":"rsync","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/rsync"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"3.4.3-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-95795.json"}}],"schema_version":"1.9.0"}
