Attackers can exploit this flaw to read sensitive files such as /etc/passwd or configuration and credential files, and the same endpoint's support for http(s) URLs also enables server-side request forgery against internal network resources. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-17.","published":"2026-10-02T19:16:38.703","modified":"2026-10-02T19:16:38.703","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://github.com/projectdiscovery/nuclei-templates/blob/main/http/vulnerabilities/weaver/weaver-ebridge-lfi.yaml"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/weaver-e-bridge-unauthenticated-arbitrary-file-read-via-saveyzjfile"},{"type":"WEB","url":"https://www.weaver.com.cn/cs/ebridge_full_log_en.html"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-10-02T19:16:38.703"}}
