{"id":"AZL-95825","summary":"CVE-2026-53783 affecting package rsync for versions less than 3.5.0-1","details":"rsync before 3.5.0 contains a time-of-check to time-of-use (TOCTOU) race condition vulnerability in the rrsync restricted shell wrapper that allows authenticated clients to escape enforced directory restrictions by substituting a symlink for a path component after validation but before transfer processing. Attackers can additionally leverage unrestricted flags such as --copy-unsafe-links, -D, and --log-file through rrsync to read or write files outside the permitted directory subtree.","modified":"2026-08-31T05:26:27Z","published":"2026-08-13T15:19:41Z","upstream":["CVE-2026-53783"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53783"}],"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-95825.json"}}],"schema_version":"1.9.0"}
