Totara · Totara Lms · CVE-2026-31283
**Name of the Vulnerable Software and Affected Versions**
Totara LMS versions prior to 19.1.5
**Description**
The forgot password API does not implement rate limiting for the target email address, which allows for an Email Bombing attack. Email Bombing is a technique where a large volume of emails is sent to a single address to overwhelm the recipient or the mail server.
**Recommendations**
Update to a version newer than 19.1.5.
As a temporary workaround, restrict access to the forgot password API endpoint to minimize the risk of exploitation.
