CVE-2026-62104 is classified as an unauthenticated remote-code-execution issue. That combination makes the vulnerability operationally severe: an attacker reportedly does not need a WordPress account before attempting exploitation, and successful exploitation could provide code execution in the context of the web server or PHP process.
The available records do not establish a specific patched version. Administrators should not assume that any release newer than 2.6.8 is safe unless the plugin’s release notes or the vendor’s advisory explicitly identify the fix for this CVE.
Organizations reviewing broader infrastructure exposure can also consult this guide to cloud security basics, including asset inventory and access-control principles.
What Is This Vulnerability?
The NVD description states: “Unauthenticated Remote Code Execution (RCE) in Migratico Lite <= 2.6.8 versions.” This confirms the security impact and the lack of an authentication prerequisite, but it does not identify the vulnerable PHP file, function, WordPress AJAX action, REST route, shortcode, upload handler, or request parameter.
The underlying technical root cause therefore remains undisclosed in the available record. It could involve command injection, unsafe file handling, an authorization failure reaching a dangerous function, insecure deserialization, or another code-execution primitive. Defenders should avoid treating any one of these mechanisms as confirmed until the Patchstack advisory or a vendor technical update provides the implementation details.
A successful attack against a typical WordPress deployment could allow an intruder to modify site content, create administrator accounts, install malicious plugins, place a web shell, steal configuration data, or use the host to attack other systems. The final impact depends on the permissions of the web-server process and the surrounding hosting environment.
CVE-2026-62104 should not be confused with an SSRF vulnerability. SSRF involves forcing a server to make requests to another destination, while RCE allows an attacker to execute code. See what SSRF is for background on that separate vulnerability class.
Who Is Affected?
The affected product is the Migratico Lite WordPress plugin. The available NVD record identifies the affected range as version 2.6.8 and earlier. This includes installations that have not been updated from 2.6.8 as well as older releases, subject to the product identification being accurate in the local environment.
Organizations should inventory every WordPress site, staging instance, backup environment, and customer-managed installation where the plugin may be present. A plugin can remain on disk even when it is not currently activated, so an inventory based only on active plugins may miss potentially relevant files or complicate incident investigation.
Use the WordPress administration interface, WP-CLI, hosting control panel, or filesystem inventory to identify installations. For example:
wp plugin get migratico-lite --field=name,version,status
If WP-CLI is unavailable, inspect the plugin directory and WordPress metadata:
find /var/www -type d -path '*/wp-content/plugins/migratico-lite' -print
grep -R "Version:" /var/www/*/wp-content/plugins/migratico-lite -n 2>/dev/null
These commands are inventory examples. Confirm the actual WordPress document root and plugin directory before running them.
CVSS Score Breakdown
NVD assigns CVE-2026-62104 a CVSS base score of 10.0, which is the highest possible base severity. The available NVD response did not include the complete CVSS vector, so the individual numeric components cannot be independently verified from the supplied data.
The published description supports several qualitative conclusions: exploitation is remote, authentication is reportedly not required, and the impact includes remote code execution. However, defenders should not infer unreported values for user interaction, scope, confidentiality, integrity, or availability. In particular, the exact CVSS version and vector should be checked directly in the NVD record if a formal risk register requires component-level scoring.
Operationally, a 10.0 score warrants emergency handling even though CVSS is not a prediction of exploitation. Internet-facing WordPress sites should be prioritized, followed by sites containing sensitive data, administrative portals, payment functionality, or privileged hosting integrations.
Exploitation Status
CVE-2026-62104 was not listed in the CISA Known Exploited Vulnerabilities catalog in the supplied assessment. No CISA KEV date, due date, required action, or ransomware-campaign designation applies. This means CISA had not added the CVE to KEV at the time of the referenced check; it does not prove that exploitation has never occurred.
No verified public proof-of-concept repository or exploit code was identified in the supplied sources. No confirmed in-the-wild exploitation was identified either. The current status is therefore: public PoC not confirmed, active exploitation not confirmed, and CISA KEV listing absent.
That status should not materially reduce remediation urgency. Unauthenticated RCE in a popular content-management ecosystem is a high-value target, and exploit details may become available after disclosure. Monitor vendor, Patchstack, NVD, CISA, threat-intelligence, and internal telemetry for status changes.
How to Detect It
Start by identifying all affected plugin versions and reviewing web-server, WordPress, PHP, WAF, and hosting-provider logs for requests to affected sites. The vulnerable endpoint and request pattern are not disclosed in the available technical information, so a reliable exploit-specific URL or parameter signature cannot be provided without risking a false detection rule.
A useful initial search is for unauthenticated requests followed by PHP errors, process-spawn events, file writes, or suspicious outbound activity. For Apache or NGINX access logs, establish a baseline with searches such as:
zgrep -hEi \
'wp-content/plugins/migratico-lite|wp-admin/admin-ajax\\.php|wp-json' \
/var/log/nginx/access.log* /var/log/apache2/access.log* 2>/dev/null
This is a triage pattern, not a confirmed exploit signature. Correlate matching requests with the same source address, timestamp, HTTP status, and subsequent filesystem or process activity. A particularly concerning pattern is an unauthenticated request to a WordPress or Migratico Lite path followed shortly by a new PHP file, a PHP error, or a child process launched by PHP-FPM or the web server.
Check for post-exploitation indicators as well:
find /var/www -type f \( -name '*.php' -o -name '*.phtml' \) \
-mtime -14 -printf '%TY-%Tm-%Td %TH:%TM %p\n' 2>/dev/null | sort
wp user list --role=administrator --fields=ID,user_login,user_registered
Review newly created administrator accounts, modified plugin and theme files, unfamiliar scheduled tasks, unexpected outbound connections, and changes to WordPress core files. Preserve relevant logs before rotating or deleting them.
Mitigation and Patching
The affected range is Migratico Lite 2.6.8 and earlier. The available advisory indicates that a mitigation is available, but the retrieved material does not establish a definitive fixed version. The correct remediation is to upgrade to the latest Migratico Lite release that the vendor or advisory explicitly confirms as fixing CVE-2026-62104.
Before upgrading, capture the current plugin version and back up the site and database. Afterward, verify the installed version and inspect the plugin’s release notes:
wp plugin update migratico-lite
wp plugin get migratico-lite --field=version
Do not treat the successful completion of wp plugin update as proof that the CVE is fixed if the resulting version is not vendor-confirmed. If the repository does not offer a confirmed remediation, disable and remove the plugin:
wp plugin deactivate migratico-lite
wp plugin delete migratico-lite
If removal is not immediately possible, restrict public access to the WordPress site or place it behind an authenticated administrative gateway and a WAF with a deny rule for requests targeting the plugin path. Because the vulnerable endpoint is not disclosed, do not rely on a narrow endpoint rule as the sole defense. Restricting access, disabling the plugin, and reducing web-server permissions are safer interim measures.
For teams standardizing credential hygiene after a suspected compromise, a password manager such as Try 1Password → can help centralize unique credentials and support safer rotation practices. It does not replace incident response or the immediate removal of vulnerable software.
If compromise is suspected, isolate the host, preserve logs and forensic images, inspect for web shells and unauthorized accounts, and rotate WordPress, database, hosting, SSH, API, and deployment credentials. Reinstall affected plugin files from a trusted source rather than assuming that deactivation removes malicious files.
