Summary
CVE-2026-62104 is a critical, unauthenticated Remote Code Execution (RCE) vulnerability affecting the Migratico Lite WordPress plugin, developed by Superweby. The flaw stems from improper control of code generation (CWE-94), allowing a remote, unauthenticated attacker to inject and execute arbitrary code on the underlying server. With a CVSS v3.1 base score of 10.0 (Critical), successful exploitation can lead to complete compromise of confidentiality, integrity, and availability of the affected WordPress site.
Technical details
- Root cause: The vulnerability is classified as CWE-94 (Improper Control of Generation of Code / Code Injection), indicating that attacker-supplied input is used to generate and execute code within the plugin without adequate sanitization or authentication checks.
- Trigger conditions: No authentication or user interaction is required to trigger the flaw (PR:N, UI:N), and the affected functionality is reachable over the network.
- Attack vector: Network (AV:N) — an attacker can exploit the vulnerability remotely by sending crafted requests to a vulnerable WordPress site running the affected plugin, with low attack complexity (AC:L).
- Impact: Full remote code execution on the web server hosting WordPress, which can result in complete site takeover, installation of backdoors/web shells, data theft (including database contents, since Migratico stores full site backups), and use of the compromised server as a pivot point for further attacks.
- Scope: The vulnerability has a "Changed" scope (S:C) in its CVSS vector, indicating the impact extends beyond the vulnerable component itself.
Affected software
- Migratico Lite (WordPress plugin) — versions up to and including 2.6.8
- Vendor: Superweby
- Package/slug:
migratico-lite
Severity
- CVSS v3.1 Base Score: 10.0 (Critical)
- Vector:
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H
Mitigation and recommended actions
- Immediate: Upgrade Migratico Lite to version 2.7.1 or later, which contains the fix for this vulnerability.
- If immediate patching is not possible:
- Temporarily deactivate the Migratico Lite plugin on any WordPress sites where it is installed until the update can be applied.
- Restrict or monitor access to the
wp-content/uploads/migratico/directory, as migration packages generated by the plugin contain full database exports (including user password hashes) and site files. - Review WordPress access logs and file integrity for signs of unauthorized code execution, unexpected admin users, or unfamiliar files/web shells if the plugin was active and internet-facing prior to patching.
- Ensure a Web Application Firewall (WAF) is in place and consider blocking suspicious requests targeting plugin-specific endpoints until the patch is confirmed applied.
