CVE-2026-63718

Summary

This vulnerability allows attackers to manipulate HTTP request and response handling in Apache servers using mod_proxy_uwsgi, potentially leading to response smuggling where crafted uwsgi responses can be interpreted inconsistently by the server. This creates a high-risk scenario for data integrity and can enable further attacks through manipulated HTTP communications.

Exploitability

Exploitation requires sending a specially crafted uwsgi response through mod_proxy_uwsgi, which is moderately difficult without prior access to the affected proxy configuration but becomes more feasible when attackers can influence uwsgi backend responses.

Blast radius

If exploited, this vulnerability could affect all Apache HTTP Server instances using mod_proxy_uwsgi with uwsgi backends, potentially allowing attackers to manipulate responses and inject malicious content across multiple web applications.

Detection

No reliable host or network indicator is derivable from the published description.

Prioritized remediation

Upgrade to Apache HTTP Server 2.4.69 or later to remediate this vulnerability.
