{"apiVersion":"1.0","identifier":"CVE-2026-53790","description":"rsync before 3.5.0 contains multiple command and argument injection vulnerabilities that allow attackers to execute arbitrary commands by supplying malicious input through several code paths, including the RSYNC_CONNECT_PROG environment variable, daemon hooks, the rsync-ssl wrapper, and remote-shell command newline injection. Attackers can inject shell metacharacters or newline characters into unsanitized user-supplied values such as hostnames and hostspecs to execute arbitrary commands under the privileges of the rsync process or the invoking user.","publishedAt":"2026-08-13T15:19:43","lastModifiedAt":"2026-08-13T16:18:06","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-53790","cvssScore":8.1,"cvssVector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00515,"riskScore":0.85,"affectedProduct":"rsync","affectedVersions":"<3.5.0","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-53790","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-53790","en":"https://www.redsauce.net/en/cves/CVE-2026-53790","fr":"https://www.redsauce.net/fr/cves/CVE-2026-53790","pt":"https://www.redsauce.net/pt/cves/CVE-2026-53790","de":"https://www.redsauce.net/de/cves/CVE-2026-53790","sk":"https://www.redsauce.net/sk/cves/CVE-2026-53790","el":"https://www.redsauce.net/el/cves/CVE-2026-53790"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-53790"}}
