Attack Path

How an attacker could exploit the issue

An attacker could exploit this vulnerability by sending a specially crafted request to a system running Gamic version 1.19 or earlier. Because no authentication is required, the attacker can directly interact with the vulnerable component, leading to PHP Object Injection. This could allow the attacker to remotely execute code on the affected server.

No authentication needed.
Triggered via specially crafted requests.
Allows remote code execution.

Frequently asked questions

What is the Gamic software?

Gamic is a WordPress theme designed to manage the visual presentation and core functionality of a website. Themes like Gamic serve as the foundational interface that users interact with, meaning they are frequently integrated into the public-facing components of a web application to deliver content and services.

What does CVE-2026-62016 mean by PHP Object Injection?

This is a security weakness classified as CWE-502, where an application improperly deserializes untrusted data. In the context of this CVE, it means the Gamic theme accepts and processes manipulated data without sufficient checks, potentially tricking the server into executing unauthorized commands.

How can an attacker trigger this vulnerability?

The flaw is triggered when an attacker sends a specifically formatted request to a system running the vulnerable Gamic code. Importantly, this does not happen through standard user interactions; it requires the attacker to actively submit crafted payloads. Systems that are not processing incoming requests via the theme's affected functions are not actively triggering this bug.

Do I need to worry if my site uses Gamic?

Halo Surface Signal indicates that because Gamic is a web theme, it is inherently designed to be publicly accessible, which often makes these components reachable over the internet. You should care if your site is internet-facing, as this exposure allows an attacker to interact with the theme directly without needing any prior login credentials or system access.

What are the first steps to address this issue?

Begin by auditing your environment to locate all active installations of the Gamic theme. Once identified, evaluate the criticality of the applications using the theme and coordinate with your internal teams to plan for updates or temporary risk-reduction strategies while awaiting further guidance from the theme vendor.
