CVE-2026-110692 in PowerPack Addons for Elementor Plugin
Summary
by MITRE • 11/04/2026
The PowerPack Addons for Elementor: Widgets, Form Styler and Templates WordPress plugin before 3.1.3 does not validate a user-supplied URL before using it in a server-side HTTP request, which could allow users with the contributor role and above to perform Server-Side Request Forgery attacks against internal and loopback resources and read the response back.

The vulnerability identified in PowerPack Addons for Elementor versions prior to 3.1.3 represents a critical server-side security flaw rooted in improper input validation of user-supplied data. Specifically, the plugin fails to adequately sanitize or validate URLs provided by users before utilizing them in server-side HTTP requests. This lack of rigorous checking allows malicious actors with contributor-level permissions and above to inject arbitrary Uniform Resource Locators into the application logic. By manipulating these inputs, an attacker can direct the vulnerable server component to initiate connections to destinations that were not intended by the original software design, fundamentally breaking the principle of least privilege regarding network access initiated from within the trusted environment.
This technical deficiency directly facilitates Server-Side Request Forgery attacks, a class of vulnerabilities where a web application fetches a resource specified by an attacker using its own back-end server code. In this specific context, the absence of validation enables attackers to target internal and loopback resources that are typically inaccessible from external networks due to firewall rules or network segmentation strategies. The ability to read the response returned by these internal services is particularly dangerous, as it transforms a simple request forgery into an information disclosure vector. Attackers can potentially extract sensitive data stored on local databases, configuration files, or other backend systems that reside behind the public-facing web server but are exposed through this unchecked HTTP client functionality.
The operational impact of this vulnerability extends beyond mere data leakage to include potential lateral movement within a compromised network infrastructure. Since loopback interfaces often host administrative panels for services like MySQL, Redis, or internal API gateways, an attacker could interact with these services directly if they lack their own authentication mechanisms or are configured to trust local connections. This capability aligns closely with the MITRE ATT&CK framework technique T1598, which covers Phishing for Inbound Credentials and potentially T1046 Network Service Discovery when used to map internal assets. Furthermore, it maps directly to CWE-918, Server-Side Request Forgery (SSRF), highlighting the failure in validating user-controlled input before server-side processing. The risk is exacerbated by the fact that contributor-level access is often granted to content creators who may not be fully vetted for security awareness, increasing the attack surface significantly compared to requiring administrator privileges.
Mitigation strategies must prioritize immediate patching and network segmentation hardening. Organizations running this plugin should upgrade immediately to version 3.1.3 or later, where the developers have implemented proper validation mechanisms to restrict allowed protocols and domains in HTTP requests. In addition to software updates, implementing strict egress filtering rules at the firewall level can mitigate the impact by blocking outbound connections from web servers to internal IP ranges that do not require external access. Application-level controls such as allowing only specific whitelisted URLs or enforcing DNS rebind protection mechanisms further reduce the risk of exploitation. Regular security audits and code reviews focusing on input validation for any function making network requests are essential preventive measures against similar SSRF vulnerabilities in WordPress ecosystems.
