{"id":"CVE-2026-71965","summary":"CyberPanel 2.4.3 Authenticated RCE via Remote Backup Feature","details":"CyberPanel 2.4.3, fixed in commit eca0c3c, contains an authenticated remote code execution vulnerability in the remote backup feature that allows authenticated attackers to gain root-level SSH access by supplying a malicious remote server address. Attackers can exploit the unverified SSH public key retrieval process to write an attacker-controlled public key directly to /root/.ssh/authorized_keys, granting persistent root access to the host system.","modified":"2026-08-15T04:25:24.051096607Z","published":"2026-08-10T18:52:40.271Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-345"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/71xxx/CVE-2026-71965.json","unresolved_ranges":[{"extracted_events":[{"last_affected":"2.4.3"}],"source":"AFFECTED_FIELD"},{"source":"CPE_FIELD","extracted_events":[{"last_affected":"2.4.3"}]}]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/71xxx/CVE-2026-71965.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-71965"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/cyberpanel-authenticated-rce-via-remote-backup-feature"},{"type":"FIX","url":"https://github.com/usmannasir/cyberpanel/commit/eca0c3cbeb35af8eaae9fafb094e8ef3cd923643"},{"type":"PACKAGE","url":"https://github.com/usmannasir/cyberpanel"},{"type":"EVIDENCE","url":"https://themcsam.github.io/posts/cyberpanel-2.4.3-vulnerabilties/"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/usmannasir/cyberpanel","events":[{"introduced":"0"},{"fixed":"eca0c3cbeb35af8eaae9fafb094e8ef3cd923643"}],"database_specific":{"source":"REFERENCES"}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-71965.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
