{"apiVersion":"1.0","identifier":"CVE-2026-53799","description":"rsync before 3.5.0 contains a symlink race condition vulnerability that allows local attackers to cause rsync to apply arbitrary ACLs or extended attributes to unintended files by substituting a symlink at a predictable destination path between the file write and the subsequent acl_set_file() or lsetxattr() call. Attackers can exploit this timing window to redirect ACL and xattr application through a crafted symlink to files outside the intended destination tree, potentially granting elevated permissions and enabling local privilege escalation.","publishedAt":"2026-08-13T15:19:52","lastModifiedAt":"2026-08-26T17:00:56","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-53799","cvssScore":6.3,"cvssVector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:N","epssProbability":0.00128,"riskScore":0.64,"affectedProduct":"rsync","affectedVersions":"<3.5.0","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-53799","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-53799","en":"https://www.redsauce.net/en/cves/CVE-2026-53799","fr":"https://www.redsauce.net/fr/cves/CVE-2026-53799","pt":"https://www.redsauce.net/pt/cves/CVE-2026-53799","de":"https://www.redsauce.net/de/cves/CVE-2026-53799","sk":"https://www.redsauce.net/sk/cves/CVE-2026-53799","el":"https://www.redsauce.net/el/cves/CVE-2026-53799"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-53799"}}
