{"apiVersion":"1.0","identifier":"CVE-2026-53798","description":"rsync before 3.5.0 contains a privilege confusion vulnerability in the name-converter subprocess uid/gid mapping that allows local attackers to cause transferred files to be owned by root by influencing name-converter responses to return empty values. When the name-converter subprocess returns an empty response for a uid or gid lookup, rsync incorrectly interprets it as a successful resolution to uid/gid 0 (root) rather than a lookup failure, and if the name-converter also signals fake super-user status, rsync proceeds with root ownership assignments for transferred files.","publishedAt":"2026-08-13T15:19:51","lastModifiedAt":"2026-08-26T17:00:56","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-53798","cvssScore":5.3,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","epssProbability":0.00278,"riskScore":0.54,"affectedProduct":"rsync","affectedVersions":"<3.5.0","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-53798","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-53798","en":"https://www.redsauce.net/en/cves/CVE-2026-53798","fr":"https://www.redsauce.net/fr/cves/CVE-2026-53798","pt":"https://www.redsauce.net/pt/cves/CVE-2026-53798","de":"https://www.redsauce.net/de/cves/CVE-2026-53798","sk":"https://www.redsauce.net/sk/cves/CVE-2026-53798","el":"https://www.redsauce.net/el/cves/CVE-2026-53798"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-53798"}}
