undici: Undici: HTTP Request Smuggling and Denial of Service due to duplicate Content-Length headers

A flaw was found in undici, a Node.js HTTP/1.1 client. A remote attacker could exploit this vulnerability by sending HTTP/1.1 requests that include duplicate Content-Length headers with different casing e.g., "Content-Length" and "content-length". This can lead to HTTP Request Smuggling, a...

curl: curl: Unauthorized access due to improper HTTP proxy connection reuse

A flaw was found in curl. This vulnerability allows curl to wrongly reuse an existing HTTP proxy connection when performing a CONNECT request to a server, even if the new request uses different authentication credentials for the HTTP proxy. This improper connection reuse could lead to an attacker...

CLEANSTART-2026-EJ93145 attacker may cause an HTTP/2 endpoint to read arbitrary amounts of header data by sending an excessive number of CONTINUATION frames

Multiple security vulnerabilities affect the kube-state-metrics package. An attacker may cause an HTTP/2 endpoint to read arbitrary amounts of header data by sending an excessive number of CONTINUATION frames. See references for individual vulnerability details...

CVE-2026-34831

A flaw was found in Rack. A remote attacker can exploit this vulnerability by requesting a non-existent path containing percent-encoded UTF-8 characters. This causes Rack::Filesfail to incorrectly calculate the Content-Length header, using Stringsize instead of Stringbytesize for multibyte...

CVE-2025-15620 HiOS Switch Platform Denial-of-Service via Web Interface

HiOS Switch Platform versions 09.1.00 through 09.4.04 and 10.0.00 through 10.3.00 contain a denial-of-service vulnerability in the web interface that allows remote attackers to reboot the affected device by sending a malicious HTTP GET request to a specific endpoint. Attackers can trigger an...
