SCA: security update for Twisted (GHSA-53xc-49m8-p798)

high Tenable Self-Hosted Container Security Plugin ID 477261

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- Twisted is an event-based framework for internet applications, supporting Python 3.6+. Prior to
26.10.0rc1, twisted.words.protocols.irc.IRC.dataReceived retains all bytes received without a line feed in
its per-connection buffer and applies no maximum line length. The twisted.words.service.IRCUser server
subclass inherits this behavior, and buffering occurs before PASS, NICK, or USER authentication commands.
An unauthenticated connection can continuously grow the buffer until the shared server process runs out of
memory and drops all users. This issue is fixed in version 26.10.0rc1. (CVE-2026-115776)

Solution

Update the Twisted library and its related packages to version 26.10.0rc1 or later.
