libevent: Libevent: HTTP header smuggling allows authorization bypass or cache poisoning
A flaw was found in Libevent, an event notification library. An unauthenticated remote attacker can exploit a vulnerability where chunked HTTP Hypertext Transfer Protocol trailers are incorrectly merged into request headers. This allows the attacker to place security-sensitive fields in trailers,...
The vulnerability of the bufferevent_socket_set_conn_address_() function in the Libevent asynchronous event library allows a hacker to cause a service failure.

CVE-2026-63384
Libevent is an event notification library. Prior to 2.1.13 and 2.2.2-alpha, libevent has an incorrect integer conversion in eventtagging.c when evtagunmarshalheader uses evtagdecodeint to decode an attacker-controlled uint32 payload length and returns it as a signed int. Values above INTMAX becom...
