CVE-2026-69211 Http4s: Set-Cookie rendering does not escape attribute delimiters

Http4s is a Scala interface for HTTP services. Prior to 0.23.35 and 1.0.0-M47, ResponseCookie.render writes attacker-influenced name, content, domain, path, and extension values without neutralizing semicolons or control characters. An application that constructs a ResponseCookie from unvalidated...

CVE-2026-55149

Vouch Proxy is an SSO and OAuth/OIDC login solution for Nginx using the authrequest module. Prior to 0.48.0, Cookie in pkg/cookie/cookie.go parses the total part count from an attacker-controlled multipart cookie name and passes the value to makestring, numParts without checking that the value is...

CVE-2026-91991

A flaw was found in Tornado. An attacker can bypass security validation in the setcookie function by using capitalized or legacy keyword arguments. This allows the attacker to inject arbitrary cookie attributes, such as Domain or SameSite, and modify cookie security settings. The consequence is t...
