CVE-2020-10109 [CRITICAL] CWE-444 CVE-2020-10109: In Twisted Web through 19.10.0, there was an HTTP request splitting vulnerability. When presented wi In Twisted Web through 19.10.0, there was an HTTP request splitting vulnerability. When presented with a content-length and a chunked encoding header, the content-length took precedence and the remainder of the request body was interpreted as a pipelined request.

Twisted is an event-based framework for internet applications, supporting Python 3.6+. The `twisted.web.util.redirectTo` function contains an HTML injection vulnerability. If application code allows an attacker to control the redirect URL this vulnerability may result in Reflected Cross-Site Scripting (XSS) in the redirect response HTML body. This vu

CVE-2020-10108 [CRITICAL] CWE-444 CVE-2020-10108: In Twisted Web through 19.10.0, there was an HTTP request splitting vulnerability. When presented wi In Twisted Web through 19.10.0, there was an HTTP request splitting vulnerability. When presented with two content-length headers, it ignored the first header. When the second content-length value was set to zero, the request body was interpreted as a pipelined request.

CVE-2022-24801 [HIGH] CWE-444 CVE-2022-24801: Twisted is an event-based framework for internet applications, supporting Python 3.6+. Prior to vers Twisted is an event-based framework for internet applications, supporting Python 3.6+. Prior to version 22.4.0rc1, the Twisted Web HTTP 1.1 server, located in the `twisted.web.http` module, parsed several HTTP request constructs more leniently than permitted by RFC 7230. This non-conformant parsing can lead to desync if requests pass through multiple

CVE-2026-42304 [HIGH] CWE-400 CVE-2026-42304: Twisted is an event-based framework for internet applications, supporting Python 3.6+. Prior to 26.4 Twisted is an event-based framework for internet applications, supporting Python 3.6+. Prior to 26.4.0rc2, the twisted.names module is vulnerable to a Denial of Service (DoS) attack via resource exhaustion during DNS name decompression. A remote, unauthenticated attacker can exploit this by sending a crafted TCP DNS packet containing deeply chained co

CVE-2024-41671 [HIGH] CWE-444 CVE-2024-41671: Twisted is an event-based framework for internet applications, supporting Python 3.6+. The HTTP 1.0 Twisted is an event-based framework for internet applications, supporting Python 3.6+. The HTTP 1.0 and 1.1 server provided by twisted.web could process pipelined HTTP requests out-of-order, possibly resulting in information disclosure. This vulnerability is fixed in 24.7.0rc1.

CVE-2022-21716 [HIGH] CWE-120 CVE-2022-21716: Twisted is an event-based framework for internet applications, supporting Python 3.6+. Prior to 22.2 Twisted is an event-based framework for internet applications, supporting Python 3.6+. Prior to 22.2.0, Twisted SSH client and server implement is able to accept an infinite amount of data for the peer's SSH version identifier. This ends up with a buffer using all the available memory. The attach is a simple as `nc -rv localhost 22 < /dev/zero`. A pat

CVE-2022-21712 [HIGH] CWE-200 CVE-2022-21712: twisted is an event-driven networking engine written in Python. In affected versions twisted exposes twisted is an event-driven networking engine written in Python. In affected versions twisted exposes cookies and authorization headers when following cross-origin redirects. This issue is present in the `twited.web.RedirectAgent` and `twisted.web.
