Echo: libsoup3: security update to 3.6.5-8

medium Tenable Cloud Security Plugin ID 461505

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - A flaw was found in libsoup, an HTTP client library. This vulnerability, known as CRLF (Carriage Return
 Line Feed) Injection, occurs when an HTTP proxy is configured and the library improperly handles URL-
 decoded input used to create the Host header. A remote attacker can exploit this by providing a specially
 crafted URL containing CRLF sequences, allowing them to inject additional HTTP headers or complete HTTP
 request bodies. This can lead to unintended or unauthorized HTTP requests being forwarded by the proxy,
 potentially impacting downstream services. (CVE-2026-1467)

Solution

Update the libsoup3 library and its related packages to version 3.6.5-8 or later.
