An authenticated user whose username or group membership would be denied by an @Group Name auth users entry can connect to a restricted module because the deny rule is silently discarded during parsing.", "title": "Vulnerability description" } ], "product_status": { "fixed": [ "CentOS-Stream-8:rsync-0:3.1.3-19.el8.1.tuxcare.els9.x86_64", "CentOS-Stream-8:rsync-daemon-0:3.1.3-19.el8.1.tuxcare.els9.noarch" ], "known_affected": [ "CentOS-Stream-8:rsync-0:3.1.3-19.el8.1.tuxcare.els1.x86_64", "CentOS-Stream-8:rsync-0:3.1.3-19.el8.1.tuxcare.els2.x86_64", "CentOS-Stream-8:rsync-0:3.1.3-19.el8.1.tuxcare.els4.x86_64", "CentOS-Stream-8:rsync-0:3.1.3-19.el8.1.tuxcare.els5.x86_64", "CentOS-Stream-8:rsync-0:3.1.3-19.el8.1.tuxcare.els6.x86_64", "CentOS-Stream-8:rsync-0:3.1.3-19.el8.1.tuxcare.els7.x86_64", "CentOS-Stream-8:rsync-0:3.1.3-19.el8.1.tuxcare.els8.x86_64", "CentOS-Stream-8:rsync-daemon-0:3.1.3-19.el8.1.tuxcare.els1.noarch", "CentOS-Stream-8:rsync-daemon-0:3.1.3-19.el8.1.tuxcare.els2.noarch", "CentOS-Stream-8:rsync-daemon-0:3.1.3-19.el8.1.tuxcare.els4.noarch", "CentOS-Stream-8:rsync-daemon-0:3.1.3-19.el8.1.tuxcare.els5.noarch", "CentOS-Stream-8:rsync-daemon-0:3.1.3-19.el8.1.tuxcare.els6.noarch", "CentOS-Stream-8:rsync-daemon-0:3.1.3-19.el8.1.tuxcare.els7.noarch", "CentOS-Stream-8:rsync-daemon-0:3.1.3-19.el8.1.tuxcare.els8.noarch" ] }, "references": [ { "category": "self", "summary": "Canonical URL", "url": "https://cve.tuxcare.com/els/cve/CVE-2026-70463" }, { "category": "external", "summary": "https://github.com/RsyncProject/rsync/releases/tag/v3.5.0", "url": "https://github.com/RsyncProject/rsync/releases/tag/v3.5.0" }, { "category": "external", "summary": "https://github.com/RsyncProject/rsync/security/advisories/GHSA-pfj8-79vq-xgvr", "url": "https://github.com/RsyncProject/rsync/security/advisories/GHSA-pfj8-79vq-xgvr" }, { "category": "external", "summary": "https://www.vulncheck.com/advisories/rsync-authorization-bypass-via-auth-users-directive-parsing", "url": "https://www.vulncheck.com/advisories/rsync-authorization-bypass-via-auth-users-directive-parsing" } ], "release_date": "2026-08-13T15:20:00Z", "remediations": [ { "category": "vendor_fix", "date": "2026-09-07T09:31:11.000159Z", "details": "Details on how to apply the fix are available at: https://cve.tuxcare.com/els/releases/CLSA-2026:1788773469", "product_ids": [ "CentOS-Stream-8:rsync-0:3.1.3-19.el8.1.tuxcare.els9.x86_64", "CentOS-Stream-8:rsync-daemon-0:3.1.3-19.el8.1.tuxcare.els9.noarch" ], "url": "https://cve.tuxcare.com/els/releases/CLSA-2026:1788773469" }, { "category": "none_available", "date": "2026-08-13T15:20:00Z", "details": "Affected", "product_ids": [ "CentOS-Stream-8:rsync-0:3.1.3-19.el8.1.tuxcare.els1.x86_64", "CentOS-Stream-8:rsync-0:3.1.3-19.el8.1.tuxcare.els2.x86_64", "CentOS-Stream-8:rsync-0:3.1.3-19.el8.1.tuxcare.els4.x86_64", "CentOS-Stream-8:rsync-0:3.1.3-19.el8.1.tuxcare.els5.x86_64", "CentOS-Stream-8:rsync-0:3.1.3-19.el8.1.tuxcare.els6.x86_64", "CentOS-Stream-8:rsync-0:3.1.3-19.el8.1.tuxcare.els7.x86_64", "CentOS-Stream-8:rsync-0:3.1.3-19.el8.1.tuxcare.els8.x86_64", "CentOS-Stream-8:rsync-daemon-0:3.1.3-19.el8.1.tuxcare.els1.noarch", "CentOS-Stream-8:rsync-daemon-0:3.1.3-19.el8.1.tuxcare.els2.noarch", "CentOS-Stream-8:rsync-daemon-0:3.1.3-19.el8.1.tuxcare.els4.noarch", "CentOS-Stream-8:rsync-daemon-0:3.1.3-19.el8.1.tuxcare.els5.noarch", "CentOS-Stream-8:rsync-daemon-0:3.1.3-19.el8.1.tuxcare.els6.noarch", "CentOS-Stream-8:rsync-daemon-0:3.1.3-19.el8.1.tuxcare.els7.noarch", "CentOS-Stream-8:rsync-daemon-0:3.1.3-19.el8.1.tuxcare.els8.noarch" ] } ], "threats": [ { "category": "impact", "details": "Critical" } ] }, { "cve": "CVE-2026-53786", "cwe": { "id": "CWE-863", "name": "Incorrect Authorization" }, "notes": [ { "category": "description", "text": "rsync before 3.5.0 contains a filter rule bypass vulnerability that allows authenticated clients to override module-level filter restrictions by supplying malicious --filter merge file directives.
