SCA: security update for pretalx (GHSA-jm8c-9f3j-4378)

medium Tenable Cloud Security Plugin ID 440652

Description

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

 - pretalx is a conference planning tool. Prior to 2026.1.0, an unauthenticated attacker can send arbitrary
 HTML-rendered emails from a pretalx instance's configured sender address by embedding malformed HTML or
 markdown link syntax in a user-controlled template placeholder such as the account display name. The most
 direct vector is the password-reset flow: the attacker registers an account with a malicious name, enters
 the victim's email address, and triggers a password reset. The resulting email is delivered from the
 event's legitimate sender address and passes SPF/DKIM/DMARC validation, making it a ready-made phishing
 vector. This vulnerability is fixed in 2026.1.0. (CVE-2026-41426)

Solution

Update the pretalx library and its related packages to version 2026.1.0 or later.
