Exposure of Sensitive Information to an Unauthorized Actor

CVE-2022-29248

Severity High
Score 8.1/10

Summary

Guzzle is a PHP HTTP client. Guzzle versions before 6.5.6 and 7.x before 7.4.3, contains a vulnerability with the cookie middleware. The vulnerability is that it is not checked if the cookie domain equals the domain of the server which sets the cookie via the Set-Cookie header, allowing a malicious server to set cookies for unrelated domains. The cookie middleware is disabled by default, so most library consumers will not be affected by this issue. Only those who manually add the cookie middleware to the handler stack or construct the client with ['cookies' => true] are affected. Moreover, those who do not use the same Guzzle client to call multiple domains and have disabled redirect forwarding are not affected by this vulnerability. As a workaround, turn off the cookie middleware.
