CVE-2026-45013 (opens in a new tab)How to fix?
Upgrade apostrophe to version 4.30.0 or higher.
Overview
apostrophe is a content management system (CMS) for Node.js. It supports in-context editing, schema-driven content types, flexible widgets and a great deal more. This module contains everything necessary to build a website with ApostropheCMS.
Affected versions of this package are vulnerable to Weak Password Recovery Mechanism for Forgotten Password via the resetRequest flow in the login module. An attacker can cause password reset emails to contain links to an attacker-controlled domain by sending a crafted Host header in a POST /api/v1/@apostrophecms/login/reset-request request, which can leak the reset token and allow the attacker to take over the victim’s account.
Notes
- The vulnerable path is gated by
passwordReset: truein the login module and only affects deployments that leaveapos.baseUrlunset.
Workarounds
- Set
baseUrlfor the ApostropheCMS Express configuration, or set theAPOS_BASE_URLenvironment variable, before enablingpasswordReset: true; this prevents password reset emails from being built from the attacker-controlledHostheader and stops reset links from pointing to an attacker-controlled domain.
