Name of the Vulnerable Software and Affected Versions SoupServer (affected versions not specified)

Description A flaw exists in SoupServer related to improper handling of HTTP requests that combine Transfer-Encoding: chunked and Connection: keep-alive headers. This can lead to an HTTP request smuggling condition. An unauthenticated, remote client can exploit this by sending crafted requests, preventing SoupServer from properly closing connections as defined by RFC 9112. Successful exploitation allows an attacker to smuggle additional requests over the persistent connection, potentially resulting in unintended request processing and denial-of-service (DoS) conditions.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
