CVE-2025-15224
Description
A flaw was found in libcurl. When doing SSH-based transfers using either SCP or SFTP, and asked to do public key authentication, curl would wrongly still ask and authenticate using a locally running SSH agent.
Statement
This vulnerability is rated Low for Red Hat products. The flaw in libcurl, when built with the libssh backend, allows it to wrongly attempt authentication via a locally running SSH agent during public key authentication for SCP or SFTP transfers. However, successful authentication still requires the SSH agent to possess the correct passphrase.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
