CVE-2025-47527 Overview
CVE-2025-47527 is a Missing Authorization vulnerability in the Icegram Collect WordPress plugin (icegram-rainmaker). The flaw exists in versions up to and including 1.3.18 and stems from incorrectly configured access control on plugin endpoints. Authenticated users with low privileges can invoke functionality that should be restricted to higher-privileged roles. The vulnerability is tracked under CWE-862: Missing Authorization and was published to the National Vulnerability Database on June 9, 2025.
Critical Impact
Authenticated attackers with low privileges can exploit broken access control in Icegram Collect to manipulate plugin data and impact site availability.
Affected Products
- Icegram Collect (icegram-rainmaker) WordPress plugin: all versions up to and including 1.3.18
- WordPress sites running the Easy Form, Lead Collection and Subscription Plugin by Icegram
- Any deployment exposing low-privileged authenticated access to the affected plugin endpoints

Technical Details for CVE-2025-47527
Vulnerability Analysis
The vulnerability resides in the Icegram Collect plugin's request-handling logic. Plugin endpoints fail to perform sufficient capability checks before executing privileged actions. An attacker who holds a low-privileged authenticated session, such as a Subscriber, can reach action handlers intended for administrators. The result is exploitation of incorrectly configured access control security levels within the plugin.
The issue maps to CWE-862: Missing Authorization. Code paths reachable via WordPress AJAX or admin-post hooks do not validate user capabilities through functions such as current_user_can() or verify nonces tied to the appropriate role. Attackers leverage this gap to invoke functions that modify plugin state, exfiltrate lead-collection data integrity boundaries, or trigger availability impact on the site.
The attack surface is network-reachable and requires only low privileges, with no user interaction. According to Patchstack telemetry referenced in the Patchstack Vulnerability Report, the EPSS probability is approximately 0.226% at the 45.4 percentile.
Root Cause
The plugin registers handlers that act on user-supplied input without enforcing role-based authorization. Capability checks and nonce validation are either missing or insufficient for the sensitivity of the action being executed. WordPress treats any authenticated user as eligible to invoke the endpoint, so the plugin must enforce its own authorization layer. Icegram Collect does not, allowing a Subscriber-level account to reach functionality reserved for higher roles.
Attack Vector
An attacker first obtains a low-privileged WordPress account on a target site. Many WordPress deployments permit open registration, which lowers the bar for this prerequisite. The attacker then issues HTTP requests directly to the vulnerable plugin endpoints. Because authorization is not enforced, the requests succeed and the attacker triggers actions with elevated effect. The CVSS vector indicates limited integrity impact and high availability impact, consistent with a broken access control flaw that can disrupt plugin data and site operation.
No public proof-of-concept exploit code is currently listed in Exploit-DB, and the vulnerability is not present on the CISA Known Exploited Vulnerabilities catalog. Refer to the Patchstack Vulnerability Report for additional technical context.
Detection Methods for CVE-2025-47527
Indicators of Compromise
- Unexpected POST requests to admin-ajax.php or admin-post.php with action parameters belonging to the icegram-rainmaker plugin originating from Subscriber-level accounts.
- Modification or deletion of Icegram Collect lead-capture forms, campaigns, or subscriber lists without corresponding administrator activity in audit logs.
- New WordPress user registrations followed shortly by HTTP requests to Icegram Collect endpoints.
Detection Strategies
- Inspect web server access logs for authenticated requests to Icegram Collect endpoints where the user role does not match the privilege expected by the action.
- Correlate WordPress user role data with HTTP request patterns to identify low-privileged accounts invoking administrative plugin actions.
- Deploy a Web Application Firewall rule that flags or blocks requests to icegram-rainmaker actions when the session cookie corresponds to a non-administrator role.
Monitoring Recommendations
- Enable verbose logging in WordPress security plugins to capture every plugin action invocation along with the calling user and role.
- Forward WordPress, PHP, and web server logs to a centralized log analytics platform and alert on anomalous spikes in Icegram Collect endpoint usage.
- Monitor user registration events and subsequent privileged-action attempts within short time windows.
How to Mitigate CVE-2025-47527
Immediate Actions Required
- Update Icegram Collect to a version newer than 1.3.18 as soon as the vendor publishes a fixed release.
- Disable the icegram-rainmaker plugin on affected sites until a patched version can be installed if a fix is not yet available.
- Disable open user registration on WordPress sites that do not require it to remove the low-privileged account prerequisite.
- Audit existing Subscriber and Contributor accounts and remove any that are not required.
Patch Information
The vulnerability affects Icegram Collect versions through 1.3.18. Administrators should consult the Patchstack Vulnerability Report and the official WordPress plugin repository for the latest fixed version and upgrade instructions. Apply the update through the WordPress admin dashboard or by deploying the patched plugin files via your standard release process.
Workarounds
- Restrict access to /wp-admin/admin-ajax.php and /wp-admin/admin-post.php for non-administrator roles by IP allowlist or reverse-proxy rules where feasible.
- Deploy a virtual patch via a Web Application Firewall that blocks requests targeting Icegram Collect actions from sessions belonging to low-privileged users.
- Enforce strong account hygiene including unique passwords and multi-factor authentication for all WordPress users to limit the chance of attacker-controlled low-privileged accounts.
