CVE-2024-11234

Configuring a proxy in a stream context might allow for CRLF injection in URIs

Published Nov 24, 2024 CVSS 3.1 · 4.8 Medium EPSS 1.1% KEV · Not listed
Description
In PHP versions 8.1.* before 8.1.31, 8.2.* before 8.2.26, 8.3.* before 8.3.14, when using streams with configured proxy and "request_fulluri" option, the URI is not properly sanitized which can lead to HTTP request smuggling and allow the attacker to use the proxy to perform arbitrary HTTP requests originating from the server, thus potentially gaining access to resources not normally available to the external user.
