What to do
AI-suggested
Until a fix is available, avoid direct access to the /optin endpoint or implement network-level protections such as rate limiting to mitigate potential DoS impact.
Description
LimeSurvey version 6.13.0 contains a vulnerability in the /optin endpoint that causes infinite HTTP redirects when accessed directly. This redirect loop can be exploited to cause a Denial of Service (DoS) by exhausting server or client resources, leading to service degradation or browser instability.
