WordPress before 5.2.4 has a Server Side Request Forgery (SSRF) vulnerability because URL validation does not consider the interpretation of a name as a series of hex characters.
Weakness
The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination.
Affected Software
| Name | Vendor | Start Version | End Version |
|---|---|---|---|
| Wordpress | Wordpress | * | 5.2.4 (excluding) |
| Wordpress | Ubuntu | bionic | * |
| Wordpress | Ubuntu | disco | * |
| Wordpress | Ubuntu | eoan | * |
| Wordpress | Ubuntu | trusty | * |
| Wordpress | Ubuntu | upstream | * |
