Lettermint Node.js SDK is the official Node.js SDK for Lettermint. In versions 1.5.0 and below, email properties (such as to, subject, html, text, and attachments) are not reset between sends when a single client instance is reused across multiple .send() calls. This can cause properties from a previous send to leak into a subsequent one, potentially delivering content or recipient addresses to unintended parties. Applications sending emails to different recipients in sequence — such as transactional flows like password resets or notifications — are affected. This issue has been fixed in version 1.5.1.

CVE-2026-23646 is a medium-severity vulnerability in OpenProject versions prior to 16.6.5 and version 17.0.0, where users can delete other users' active sessions due to improper session ownership validation. This allows an attacker to unauthenticate other users by iterating session IDs in DELETE requests without needing elevated permissions or user interaction. Although no sensitive session data is exposed, the ability to forcibly log out users can disrupt availability and workflow. The issue was fixed in OpenProject 16.6.5 and 17.

The 404 Solution plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.35.17 via the export feature. This makes it possible for unauthenticated attackers to extract data such as redirects including GET parameters which may reveal sensitive information. On most sites this is unlikely to be the case.
