GHSA-7j9h-3jxf-3vrf
Denial of service vulnerability on Password reset page
Packages
Details
As written in the advisory (Markdown source, shown as plain text).
### Impact
Previous versions of Kiwi TCMS do not impose rate limits which makes it easier to attempt denial-of-service attacks against the Password reset page. An attacker could potentially send a large number of emails if they know the email addresses of users in Kiwi TCMS. Additionally that may strain SMTP resources.
### Patches
Users should upgrade to v12.0 or later.
### Workarounds
Users may install and configure a rate-limiting proxy in front of Kiwi TCMS such as Nginx and/or configure rate limits on their email server when possible.
