cpython: email header injection due to unquoted newlines

A flaw was found in the email module in the Python standard library. When serializing an email message, the BytesGenerator class fails to properly quote newline characters for email headers. This issue is exploitable when the LiteralHeader class is used as it does not respect email folding rules,...

CVE-2026-3632

A flaw was found in libsoup, a library used by applications to send network requests. This vulnerability occurs because libsoup does not properly validate hostnames, allowing special characters to be injected into HTTP headers. A remote attacker could exploit this to perform HTTP smuggling, where...

CVE-2026-3634

A flaw was found in libsoup. An attacker controlling the value used to set the Content-Type header can inject a Carriage Return Line Feed CRLF sequence due to improper input sanitization in the soupmessageheaderssetcontenttype function. This vulnerability allows for the injection of arbitrary...

AZL-80232 CVE-2026-3633 affecting package libsoup 3.4.4-16

A flaw was found in libsoup. A remote attacker, by controlling the method parameter of the soupmessagenew function, could inject arbitrary headers and additional request data. This vulnerability, known as CRLF Carriage Return Line Feed injection, occurs because the method value is not properly...
