{"id":"CVE-2026-53790","summary":"rsync \u003c 3.5.0 Command Injection via Multiple Code Paths","details":"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.","aliases":["GHSA-5hcf-7xxm-rmqq"],"modified":"2026-08-15T11:46:14.590577355Z","published":"2026-08-13T14:37:41.052Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-78","CWE-88"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53790.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53790.json"},{"type":"ADVISORY","url":"https://github.com/RsyncProject/rsync/releases/tag/v3.5.0"},{"type":"ADVISORY","url":"https://github.com/RsyncProject/rsync/security/advisories/GHSA-5hcf-7xxm-rmqq"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53790"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/rsync-command-injection-via-multiple-code-paths"},{"type":"PACKAGE","url":"https://github.com/RsyncProject/rsync"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/rsyncproject/rsync","events":[{"introduced":"0"},{"fixed":"471e17dc0d68233db84db11be82c9f62f4661214"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"0"},{"last_affected":"3.4.4"}]}}],"versions":["v3.4.3","v3.4","v3.2.7","v3.4.1","v3.4.2","v3.4.0","v3.3.0","v3.3.0pre1","v3.2.7pre1","v3.2.6","v3.2.5","v3.2.5pre2","v3.2.5pre1","v3.2.4","v3.2.4pre4","v3.2.4pre3","v3.2.4pre2","v3.2.4pre1","v3.2.3","v3.2.3pre1","v3.2.2","v3.2.2pre3","v3.2.2pre2","v3.2.2pre1","v3.2.1","v3.2.1pre1","v3.2.0","v3.2.0pre3","v3.2.0pre2","v3.2.0pre1","v3.1.3","v3.1.3pre1","v3.1.2","v3.1.2pre1","v3.1.1","v3.1.1pre2","v3.1.1pre1","v3.1.0","v3.1.0pre1","v3.0.3","v3.0.3pre3","v3.0.3pre2","v3.0.3pre1","v3.0.2","v3.0.1","v3.0.1pre3","v3.0.1pre2","v3.0.1pre1","v3.0.0","v3.0.0pre10","v3.0.0pre9","v3.0.0pre8","v3.0.0pre7","v3.0.0pre6","v3.0.0pre5","v3.0.0pre4","v3.0.0pre3","v3.0.0pre2","v3.0.0pre1","v2.6.9","v2.6.9pre3","v2.6.9pre2","v2.6.9pre1","v2.6.8","v2.6.8pre1","v2.6.7","v2.6.7pre3","v2.6.7pre2","v2.6.7pre1","v2.6.6pre1","v2.6.5","v2.6.5pre2","v2.6.5pre1","v2.6.4","v2.6.4pre4","v2.6.4pre3","v2.6.4pre2","v2.6.4pre1","v2.6.3","v2.6.3pre2","v2.6.3pre1","v2.6.2","v2.6.2pre1","v2.6.1","v2.6.1pre2","v2.6.1pre1","v2.6.0","v2.6.0pre2","v2.6.0pre1","v2.5.6","v2.5.5","v2.5.5.rc1","v2.5.4","v2.5.4pre1","v2.5.3","v2.5.3pre1","v2.5.2","v2.5.2pre3","v2.5.2pre2","v2.5.2pre1","v2.5.1","v2.5.1pre3","v2.5.1pre2","v2.5.1pre1","v2.5.0","v2.4.7pre4","v2.4.7pre2","mbp_bk_export0","v2.4.6","v2.4.5","v2.4.4","v2.4.3","v2.4.2","v2.4.1","v2.4.0","v2.3.2","v2.3.1","v2.3.0","v2.2.1","v2.2.0","v2.1.1","v2.1.0","v2.0.19","v2.0.18","v2.0.17","v2.0.16","v2.0.15","v2.0.14","v2.0.13","v2.0.12","v2.0.11","v2.0.10","v2.0.9","v2.0.8","v2.0.7","v2.0.6","v2.0.5","v2.0.4","v2.0.3","v2.0.2","v2.0.1","v2.0.0","v1.7.4","v1.7.3","v1.7.2","v1.7.1","v1.7.0","v1.6.9","v1.6.8","v1.6.7","v1.6.6","v1.6.5","v1.6.4"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53790.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
