CVE-2020-14002 is an information leak vulnerability affecting PuTTY versions 0.68 through 0.73, as well as related Fedora and NetApp products. This medium-severity flaw (CVSS 5.9) stems from an observable discrepancy during algorithm negotiation, allowing a man-in-the-middle attacker to target initial connection attempts where no host key is cached. While it could lead to high confidentiality impact, its attack complexity is high. There is currently no evidence of active exploitation, public exploit code, or significant community discussion surrounding this vulnerability.
