CVE-2025-12886 describes a Server-Side Request Forgery (SSRF) vulnerability found in the Oxygen Theme for WordPress. This flaw allows unauthenticated attackers to make web requests to arbitrary locations, potentially querying or modifying information from internal services. The vulnerability affects versions up to and including 6.0.8, and it has been fixed in version 6.0.9.
CVE-2025-12886 in the Oxygen WordPress theme poses a significant risk to websites utilizing it. This vulnerability is a Server-Side Request Forgery (SSRF). This means an unauthenticated attacker can manipulate the theme to make web requests to arbitrary locations, such as internal services that are normally inaccessible from the outside. An attacker could potentially access sensitive information, modify internal data, or even use the server to attack other systems on the internal network. The vulnerability is rated as 7.2 in severity according to CVSS, indicating a high risk. Updating the theme to version 6.0.9 or later is crucial to mitigate this risk.
The vulnerability resides within the 'laboratorcalcroute' AJAX action of the Oxygen theme. An attacker can exploit this by sending a malicious AJAX request that manipulates the theme to make a request to an arbitrary URL. Because the AJAX action doesn't require authentication, anyone can exploit the vulnerability. The potential impact is high, as an attacker can access sensitive information or even compromise server security. Exploitation is relatively straightforward, increasing the risk of it being used by attackers.
