undici: undici: Weakening of cookie SameSite policy due to incorrect parsing of Set-Cookie header

A flaw was found in undici. When undici processes Set-Cookie headers, it incorrectly interprets the SameSite attribute, accepting partial matches instead of exact ones. This allows a malicious server to downgrade a cookie's SameSite policy to a less secure setting, potentially leading to unintend...

PYSEC-2026-2646 Microdot has HTTP response splitting in Response.set_cookie()

Impact The Response.setcookie method does not sanitize its string arguments, and in particular will not detect the presence of the \r\n sequence in them. This can be a potential source of header injection attacks. For a header injection attack through this issue to be possible, an attacker must...

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...
