Until a fix is available, users should consider implementing additional CSRF protections manually or restrict access to trusted users only. Monitoring for suspicious activity related to state-changing requests is advisable. Avoid interacting with untrusted links or websites that could trigger CSRF attacks.
Description
Leantime version 3.6.2 has a cross-site request forgery (CSRF) vulnerability due to the exclusion of the Laravel VerifyCsrfToken middleware from the global middleware stack. This flaw allows unauthenticated attackers to perform state-changing actions on behalf of authenticated users by tricking them into submitting malicious requests. Such actions include creating or deleting projects, modifying settings, and changing permissions. There is no information about a patch or fix currently available.
