RHSA-2026:82895
Vulnerability from csaf_redhat - Published: 2026-10-14 11:39 - Updated: 2026-10-17 12:55Summary
Red Hat Security Advisory: Red Hat Hardened Images RPMs bug fix and enhancement update
Severity
Important
Scope
26 vulnerabilities in this advisory, including CVE-2026-87865.
CVE-2026-87865
A flaw was found in curl. When libcurl is built with the libssh2 backend and uses a hashed known-hosts file, host key verification can mistakenly report a key mismatch as a missing key to custom verification callbacks. A remote attacker who intercepts or controls the Secure Shell (SSH) connection can exploit this flaw to make a previously pinned server appear as a new host. As a result, the application may inadvertently authenticate to an untrusted server, leading to credential exposure and the receipt of malicious data.
Fixed: 13 products

Details
When libcurl uses libssh2 with a hashed known_hosts file, an unrelated initial entry can cause host key validation to report a key mismatch as a missing key to the CURLOPT_SSH_KEYFUNCTION callback.
