{"id":"AZL-95777","summary":"CVE-2026-70454 affecting package rsync for versions less than 3.5.0-1","details":"rsync 3.2.0 through 3.2.3 (openssl mode) and rsync-ssl through 3.4.4 (stunnel mode) contain a TLS certificate validation vulnerability that allows on-path attackers to intercept encrypted sessions by presenting self-signed or otherwise invalid certificates. Attackers can exploit the failure to validate server TLS certificates against a trusted CA or verify certificate hostname matching to decrypt or tamper with rsync session content without detection by the client.","modified":"2026-08-31T05:26:27Z","published":"2026-08-13T15:19:59Z","upstream":["CVE-2026-70454"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-70454"}],"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-95777.json"}}],"schema_version":"1.9.0"}
