CVE-2026-3632
3.9 · LOWOverview
CVE-2026-3632 is a low-severity vulnerability affecting gnome libsoup. It was published on March 17, 2026 and has a CVSS 3.1 base score of 3.9 (LOW).
This vulnerability has a CVSS 3.1 base score of 3.9, rated LOW. It can be exploited remotely over the network. Some level of privileges is required for exploitation.
Technical Description
A flaw was found in libsoup, a library used by applications to send network requests. This vulnerability occurs because libsoup does not properly validate hostnames, allowing special characters to be injected into HTTP headers. A remote attacker could exploit this to perform HTTP smuggling, where they can send hidden, malicious requests alongside legitimate ones. In certain situations, this could lead to Server-Side Request Forgery (SSRF), enabling an attacker to force the server to make unauthorized requests to other internal or external systems. The impact is low, as SoupServer is not actually used in internet infrastructure.
Remediation
Check the references section for vendor advisories and patches from gnome. Update libsoup to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
