Name of the Vulnerable Software and Affected Versions
AIOHTTP versions prior to 3.14.4
Description
A subdomain can remove the Host-Only scope from an existing parent-domain cookie. This allows a user accessing an untrusted subdomain to have host-only protections stripped from cookies, though the impact is limited if applications do not reflect those cookies to a browser.
Recommendations
Update to version 3.14.4.
