- CVE-2026-27448:
pyOpenSSL is a Python wrapper around the OpenSSL library. Starting in
version 0.14.0 and prior to version 26.0.0, if a user provided
callback to `set_tlsext_servername_callback` raised an unhandled
exception, this would result in a connection being accepted. If a user
was relying on this callback for any security-sensitive behavior, this
could allow bypassing it. Starting in version 26.0.0, unhandled
exceptions now result in rejecting the connection.

- CVE-2026-27459:
pyOpenSSL is a Python wrapper around the OpenSSL library. Starting in
version 22.0.0 and prior to version 26.0.0, if a user provided
callback to `set_cookie_generate_callback` returned a cookie value
greater than 256 bytes, pyOpenSSL would overflow an OpenSSL provided
buffer. Starting in version 26.0.0, cookie values that are too long
are now rejected.
