Thunderbird ignored the configuration that required STARTTLS security for SMTP connections. A MITM could perform a downgrade attack to intercept transmitted messages, or could take control of the authenticated session to execute SMTP commands chosen by the MITM. If an unprotected authentication...

CVE-2026-40594 pyLoad: Session Cookie Security Downgrade via Untrusted X-Forwarded-Proto Header Spoofing (Global State Race Condition)

pyLoad is a free and open-source download manager written in Python. Prior to 0.5.0b3.dev98, the setsessioncookiesecure beforerequest handler in src/pyload/webui/app/init.py reads the X-Forwarded-Proto header from any HTTP request without validating that the request originates from a trusted prox...

CVE-2026-26994

A flaw was found in uTLS. An active network attacker could exploit this vulnerability by manipulating the initial connection message ClientHello during the TLS handshake. This manipulation forces a downgrade from the more secure TLS 1.3 protocol to an older, less secure version like TLS 1.2. As a...

CVE-2026-26994

uTLS is a fork of crypto/tls, created to customize ClientHello for fingerprinting resistance while still using it for the handshake. In versions 1.6.7 and below, uTLS did not implement the TLS 1.3 downgrade protection mechanism specified in RFC 8446 Section 4.1.3 when using a uTLS ClientHello spe...
