CVE-2026-69215

Http4s is a Scala library for HTTP services. Prior to 0.23.35 and 1.0.0-M47 , its CookieJar client middleware uses unanchored substring checks instead of proper RFC 6265 domain and path matching when deciding whether to attach a stored cookie. As a result, a cookie intended for example.com can be...

CVE-2026-69215 Http4s: CookieJar middleware matches by substring, leaking cookies cross-origin

Http4s is a Scala interface for HTTP services. Prior to 0.23.35 and 1.0.0-M47, The CookieJar client middleware uses unanchored substring checks instead of RFC 6265 domain and path matching when deciding whether to attach a stored cookie. A cookie for example.com can consequently be sent to an...

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...

Vouch Proxy is an SSO and OAuth/OIDC login gateway for Nginx. In versions prior to 0.48.0 (specifically v0.47.2), the Cookie() function in pkg/cookie/cookie.go parses the multipart cookie part count from an attacker-controlled cookie name and passes it unbounded to make([]string, N). A single una...
