PYSEC-2026-2369 apache-airflow-providers-keycloak: Missing OAuth 2.0 State and PKCE Enables Login CSRF and Session Fixation

The Keycloak authentication manager in apache-airflow-providers-keycloak did not generate or validate the OAuth 2.0 state parameter on the login / login-callback flow, and did not use PKCE. An attacker with a Keycloak account in the same realm could deliver a crafted callback URL to a victim's...

undici: undici vulnerable to HTTP header injection via Set-Cookie percent-decoding

A flaw was found in undici. The cookie parser in the parseSetCookie function incorrectly decodes cookie values, which is contrary to standard specifications. This vulnerability allows an attacker-controlled upstream to inject arbitrary HTTP response headers, such as Set-Cookie, Location, or...

CVE-2026-56813

Improper Neutralization of Parameter/Argument Delimiters vulnerability in elixir-plug plug allows an attacker to inject or override HTTP cookie attributes. The Plug.Conn.Cookies.encode/2 function in lib/plug/conn/cookies.ex builds the Set-Cookie response header by interpolating the cookie value a...
