SCA: security update for lettermint (GHSA-49pc-8936-wvfp)

medium Tenable Cloud Security Plugin ID 437923

Description

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

 - 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.
