Technical Analysis
The Eventin WordPress plugin prior to version 4.1.21 does not properly validate webhook URLs supplied by users nor verify that the user owns the event associated with the webhook. This flaw enables users with contributor-level privileges or above to cause the server to make arbitrary HTTP requests to external or internal systems, constituting a blind SSRF vulnerability.
Potential Impact
An attacker with contributor-level access or higher can cause the server to make HTTP requests to arbitrary hosts. The CVSS score of 2.7 (low) reflects limited confidentiality impact and no integrity or availability impact. This vulnerability does not allow direct data disclosure or modification but could be used to probe internal networks or services.
Mitigation Recommendations
A fixed version 4.1.21 or later of the Eventin plugin should be applied to remediate this vulnerability. Since the vulnerability is fixed in 4.1.21, upgrading to this or a later version is the recommended mitigation.
