CVE-2026-47874

A flaw was found in the Reactor Netty HTTP server. A remote attacker can exploit this vulnerability by sending HTTP/1.1 pipelined requests over a single connection. This action causes the server to consume an excessive amount of memory, leading to a Denial of Service DoS...

Astra Linux – Vulnerability in Twisted

In Twisted Web version 19.10.0, there was an HTTP request splitting vulnerability. When two content-length headers were provided, the system ignored the first header. When the second content-length value was set to zero, the request body was interpreted as a pipelined request...

Astra Linux – Vulnerability in Waitress

Waitress version 1.3.1 would parse the Transfer-Encoding header and only look for a single string value. If that value was not in the “chunked” format, it would proceed using the Content-Length header instead. According to the HTTP standard, Transfer-Encoding should be a comma-separated list, wit...

netty: io.netty/netty-codec-http: Netty: Incorrect HTTP response parsing leads to data confusion

A flaw was found in Netty, an asynchronous, event-driven network application framework. A remote attacker could exploit this vulnerability by sending a specific sequence of HTTP responses 103, followed by a 200 with a GET body, then another 200 for a HEAD request when the client pipelines GET the...

GHSA-W6F5-V2H6-G786 Predis: Redis command injection and denial of service via CRLF smuggling in pipelined commands on aggregate connections

Summary An improper CRLF neutralization flaw in Predis' pipeline handling on aggregate connections lets an unauthenticated attacker who can influence any pipelined argument — a value or a key, e.g. a URL slug used as a cache key — smuggle arbitrary Redis commands into the connection. - On cluster...

CVE-2026-84372

Predis , a PHP client for Redis and Valkey, is affected by a critical (CVSS 9.8) Redis command injection and denial of service vulnerability in versions 3.0.0-RC1 through 3.3.0 . The root cause lies in AbstractAggregateConnection::write(), which reparses an already serialized RESP buffer using ex...

CVE-2026-84372 Predis: Redis command injection and denial of service via CRLF smuggling in pipelined commands on aggregate connections

Predis is a flexible and feature-complete Redis and Valkey client for PHP. From version 3.0.0-RC1 until version 3.3.0, pipeline handling on aggregate cluster and replication connections reparses an already serialized RESP buffer in AbstractAggregateConnection::write by splitting it with...
