CVE-2026-1002

A flaw was found in Vert.x. The Web static handler component cache can be manipulated to deny the access to static files served by the handler using specifically crafted request URIs, preventing legitimate users from accessing static files with an HTTP 404 response.

5.3 (Medium)
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L
CWE-444 - Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling')
Vendor Fix Before applying the update, back up your existing installation, including all applications, configuration files, databases and database settings, and so on. The References section of this erratum contains a download link (you must log in to download the update). https://access.redhat.com/errata/RHSA-2026:8159
Workaround To mitigate this vulnerability, consider disabling the static handler cache by configuring the StaticHandler instance with setCachingEnabled(false), for example: ~~~ StaticHandler staticHandler = StaticHandler.create().setCachingEnabled(false); ~~~
CVE-2026-33870

A flaw was found in Netty. A remote attacker could exploit this vulnerability by sending specially crafted HTTP/1.1 chunked transfer encoding extension values. Due to incorrect parsing of quoted strings, this flaw enables request smuggling attacks, potentially allowing an attacker to bypass security controls or access unauthorized information.

7.5 (High)
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N
CWE-444 - Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling')
Vendor Fix Before applying the update, back up your existing installation, including all applications, configuration files, databases and database settings, and so on. The References section of this erratum contains a download link (you must log in to download the update). https://access.redhat.com/errata/RHSA-2026:8159
Workaround Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
CVE-2026-33871

A flaw was found in Netty. A remote user can trigger a Denial of Service (DoS) against a Netty HTTP/2 server by sending a flood of CONTINUATION frames. The server's lack of a limit on these frames, coupled with a bypass of size-based mitigations using zero-byte frames, allows an attacker to consume excessive CPU resources. This can render the server unresponsive with minimal bandwidth usage.

7.5 (High)
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
CWE-770 - Allocation of Resources Without Limits or Throttling
Vendor Fix Before applying the update, back up your existing installation, including all applications, configuration files, databases and database settings, and so on. The References section of this erratum contains a download link (you must log in to download the update). https://access.redhat.com/errata/RHSA-2026:8159
