CVE-2026-82209

A flaw was found in libcurl when libpsl support is enabled. A remote attacker could exploit this vulnerability by setting a Set-Cookie header with a Domain attribute that explicitly matches a public suffix. This improper handling causes libcurl to save the cookie with a wildcard domain scope,...

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.

Coder's subdomain workspace app routing trusts unauthenticated X-Forwarded-Host header, enabling cross-app data access

Summary The workspace app proxy resolves the target app from httpapi.RequestHost which prefers the X-Forwarded-Host header over the real Host header. No middleware strips X-Forwarded-Host before routing and the header is not browser-forbidden so client-side JavaScript can set it on fetch calls...
