SCA: security update for Twisted (GHSA-8pqf-f4m5-798g)

medium Tenable Self-Hosted Container Security Plugin ID 473712

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+. In 25.5.0 and
 earlier, wildcardToRegexp() in twisted/mail/imap4.py translates the IMAP asterisk and percent wildcards
 but passes all other characters from an authenticated client's LIST or LSUB pattern directly to
 re.compile(), allowing nested or otherwise expensive regular expression constructs to cause catastrophic
 backtracking when matched against mailbox names. Because Twisted uses a cooperative single-threaded
 reactor, the blocking match suspends all server input and output for the duration of the match. No fixed
 release is available as of this review. (CVE-2026-106454)
