5 CVE

  1. CVE-2026-93558 7.5 Élevée

    Red Hat Build of Apache Camel 3.33.3.SP2 · Red Hat Build of Debezium 3.6 · Red Hat build of Quarkus 3.27.5.SP2 · Red Hat build of Quarkus 3.33.3.SP2

    A flaw was found in Netty's WebSocketServerExtensionHandler. A remote, unauthenticated attacker can exploit this vulnerability by using HTTP/1.1 pipelining to send requests faster than the application can respond. This leads to an unbounded growth of a per-connection queue, consuming excessive memory. Eventually, this can cause the Java Virtual Machine (JVM) to exhaust its heap, resulting in a Denial of Service (DoS) for the affected server.

  2. CVE-2026-93491 7.5 Élevée

    Red Hat Build of Apache Camel 3.33.3.SP2 · Red Hat Build of Debezium 3.6 · Red Hat build of Quarkus 3.27.5.SP2 · Red Hat build of Quarkus 3.33.3.SP2

    A flaw was found in Netty's HttpServerCodec. A remote, unauthenticated attacker can exploit this vulnerability by pipelining HTTP/1.1 requests on a single connection and withholding reads. This action causes the methodOverflowQueue to grow without limit, leading to unbounded heap memory consumption and a denial of service due to memory exhaustion.

  3. CVE-2026-87743 7.5 Élevée

    Red Hat build of Quarkus 3.27.5.SP2 · Red Hat build of Quarkus 3.33.3.SP2 · Red Hat Exploit Intelligence · Red Hat OpenShift Serverless

    A flaw was found in Quarkus HTTP security. An unauthenticated attacker can exploit a discrepancy in how paths are normalized between the security matcher and HTTP request dispatchers. This allows the attacker to craft a URL that the security matcher considers public, but which is then routed to a protected endpoint, leading to an authorization bypass and potential unauthorized access to sensitive information.

  4. CVE-2026-87935 8.1 Élevée

    ichurakov Paid Downloads

    The Paid Downloads plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 3.15 via the admin_request_handler function. This is due to missing authorization and file type validation in the admin_request_handler function, which is reachable unauthenticated via is_admin() returning true for /wp-admin/admin-post.php. This makes it possible for unauthenticated attackers to upload files that may be executable, which makes remote code execution possible. On Apache servers where AllowOverride is enabled, an .htaccess file placed in the upload directory may block direct HTTP retrieval of uploaded files, limiting exploitability to stacks that do not honor .htaccess directives such as nginx, LiteSpeed, and Apache with AllowOverride None.

  5. CVE-2026-90937 9.9 Critique

    froxlor

    froxlor versions before 2.2.5 fail to validate newline characters in subdomain redirect URLs, allowing authenticated customers to inject arbitrary nginx or Apache configuration directives. Attackers can supply URLs containing literal newlines that are written verbatim into vhost config files during cron rebuild, enabling web server configuration corruption, denial of service, or hijacking of HTTP responses across hosted domains.
