CVE-2026-9547SSH improper host validation

curl curl Yayım: (4 ay önce)

Açıklama

When a libcurl-based application performs transfers via `SCP://` or `SFTP://` and utilizes the `CURLOPT_SSH_KEYFUNCTION` callback, it may silently accept an untrusted server. This vulnerability occurs when a server presents a host key type that does not match the specific key type already recorded for that host in the `known_hosts` file. Instead of rejecting the mismatch, the callback mechanism fails to properly enforce the restriction, allowing the connection to succeed without warning and risking a potential man-in-the-middle attack.

Zayıflık türü (CWE): CWE-297

Veri: CVE.org, NVD, CISA KEV, FIRST EPSS, Ubuntu. Bilgiler kaynaktaki haliyle, İngilizce yayımlanır.
