CVE-2026-64785

A flaw was found in SwiftNIO HTTP/2. This vulnerability allows a remote attacker to perform HTTP request smuggling or response splitting. The issue stems from insufficient validation of incoming HTTP/2 HEADERS frames, which are parts of an HTTP/2 request. This allows special control characters,...

CVE-2026-18369

A flaw was found in Dogtag PKI's ACME responder where the HTTP-01 challenge validator accepts IP address literals as dns identifiers and follows HTTP redirects without validating that the target is a public address. An unauthenticated ACME account holder can exploit this to perform server-side...

CVE-2026-18369 Dogtag-pki: pki-core: redhat-pki: pki: acme http-01 validation ssrf via ip literal identifiers and unvalidated redirects

A flaw was found in Dogtag PKI's ACME responder where the HTTP-01 challenge validator accepts IP address literals as dns identifiers and follows HTTP redirects without validating that the target is a public address. An unauthenticated ACME account holder can exploit this to perform server-side...

io.netty/netty-codec-http2: Netty: Denial of Service via HTTP/2 DATA frame memory leak

A flaw was found in Netty, a network application framework. A remote, unauthenticated attacker can exploit this vulnerability by sending specially crafted HTTP/2 DATA frames to applications that use Netty and have HTTP/2 content decompression enabled. This can lead to memory exhaustion, causing t...

org.apache.httpcomponents.core5/httpcore5-h2: Apache HttpComponents Core: Denial of Service via oversized HTTP/2 HPACK header blocks

A flaw was found in Apache HttpComponents Core. This vulnerability, located in the HTTP/2 HPACK decoder, allows a remote attacker to cause a denial of service. By sending oversized compressed header blocks, an attacker can exhaust memory resources before the system's configured header list size...

org.apache.httpcomponents.core5/httpcore5: Apache HttpComponents Core: Denial of Service via excessive HTTP headers

A flaw was found in Apache HttpComponents Core. This uncontrolled resource consumption vulnerability in the HTTP/1.1 message parser allows a remote attacker to cause a denial of service through memory exhaustion. This can be triggered by sending messages with an excessive number of headers or...

org.apache.camel/camel-vertx-http: Apache Camel (camel-vertx-http): Remote Code Execution via Deserialization of Untrusted Data

A flaw was found in the camel-vertx-http component of Apache Camel. This vulnerability, a Deserialization of Untrusted Data, could allow a remote attacker to execute arbitrary code. By controlling the backend server or acting as a man-in-the-middle, an attacker could send a specially crafted...

vertx-core: Eclipse Vert.x: Information disclosure via improper handling of HTTP 30x redirects

A flaw was found in Eclipse Vert.x. The DefaultRedirectHandler in vertx-core improperly handles HTTP 30x redirects by propagating all request headers, including sensitive authentication and session credentials, to cross-origin redirect destinations. An attacker can exploit this by redirecting a...

io.netty/netty-codec-http: Netty: Memory exhaustion in netty-codec-http (decompression bomb)

A flaw was found in the Netty netty-codec-http component. A remote attacker can send HTTP requests containing highly compressed data. The HTTP decoder in netty-codec-http fails to properly limit the decompression of this content, causing the system to consume excessive memory. This can lead to...

httplib2: httplib2: Denial of Service via unbounded decompression of HTTP response bodies

A flaw was found in httplib2, a Python HTTP client library. This vulnerability allows a malicious or compromised HTTP server to send a small compressed data payload that, when decompressed by httplib2, expands to an extremely large size in memory. This unbounded decompression can lead to a Denial...
