CVE-2026-27448 (GCVE-0-2026-27448)

Vulnerability from cvelistv5 – Published: 2026-03-17 23:24 – Updated: 2026-03-18 20:18

Title

pyOpenSSL allows TLS connection bypass via unhandled callback exception in set_tlsext_servername_callback

Summary

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.

Severity

1.7 (Low)

CVE-2026-27459 (GCVE-0-2026-27459)

Vulnerability from cvelistv5 – Published: 2026-03-17 23:34 – Updated: 2026-03-18 19:52

Title

pyOpenSSL DTLS cookie callback buffer overflow

Summary

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.

Severity

CVE-2026-31958 (GCVE-0-2026-31958)

Vulnerability from cvelistv5 – Published: 2026-03-11 19:27 – Updated: 2026-04-01 14:32

Title

Tornado has a DoS due to too many multipart parts

Summary

Tornado is a Python web framework and asynchronous networking library. In versions of Tornado prior to 6.5.5, the only limit on the number of parts in multipart/form-data is the max_body_size setting (default 100MB). Since parsing occurs synchronously on the main thread, this creates the possibility of denial-of-service due to the cost of parsing very large multipart bodies with many parts. This vulnerability is fixed in 6.5.5.

Severity

8.7 (High)
