The WPLP Cookie Consent – Cookie Banner & Consent Management for GDPR, CCPA & Google Consent Mode plugin for WordPress is vulnerable to arbitrary file upload due to missing file type validation in the saas_upload_logo() function combined with an authorization bypass on the WPLP connector REST endpoints in all versions up to, and including, 4.4.1. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible.
Security readout for executives and security teams
Plain-English summary
Affected WordPress sites may let anyone upload arbitrary files without signing in. If the server accepts and executes a malicious uploaded file, attackers could potentially take complete control of the site, alter content, steal data, or disrupt service.
Executive priority
Treat as an immediate remediation priority for internet-facing sites. Inventory affected installations, contain exposure, and apply vendor-confirmed remediation promptly. Because compromise could affect confidentiality, integrity, and availability, investigate exposed systems for suspicious uploads or endpoint activity rather than assuming an update alone resolves prior intrusion.
Technical view
WPLP Cookie Consent through version 4.4.1 has missing file-type validation in saas_upload_logo(), combined with an authorization bypass affecting connector REST endpoints. The unauthenticated, network-accessible flaw can permit arbitrary server-side file uploads and may enable remote code execution. It is classified as CWE-434 with CVSS 3.1 score 9.8.
Likely exposure
Internet-facing WordPress installations running WPLP Cookie Consent 4.4.1 or earlier are potentially exposed, particularly where the connector REST endpoint is reachable. The supplied affected-version metadata is internally inconsistent, but the title and description consistently specify versions through 4.4.1.
Exploitation context
No active exploitation is established by the supplied sources, and the CVE is not identified as being in CISA KEV. Nevertheless, exploitation requires no authentication or user interaction and has low stated complexity. Successful file upload may lead to remote code execution, depending on server handling and upload location.
Researcher notes
The reported weakness chains authorization bypass with inadequate upload validation. Evidence supports arbitrary unauthenticated file upload; remote code execution is possible, not guaranteed. Execution depends on file placement and web-server behavior. The supplied WordPress changeset is relevant, but the bundle does not explicitly name a fixed release or document exploitation in the wild.
Mitigation direction
Identify every WordPress site running WPLP Cookie Consent 4.4.1 or earlier.
Obtain and apply a vendor-confirmed release that addresses the vulnerability.
Disable or remove the plugin until remediation if a confirmed safe release is unavailable.
Restrict access to affected connector REST endpoints where operationally feasible.
Follow Wordfence and WordPress plugin guidance for updated remediation information.
Validation and detection
Confirm the installed plugin version across production, staging, and dormant WordPress sites.
Determine whether the WPLP connector REST endpoints are externally reachable without authentication.
Review web and security logs for suspicious unauthenticated requests to the upload-logo endpoint.
Inspect upload locations for unexpected files, especially executable or recently created content.
After remediation, verify unauthorized uploads are rejected and expected consent functions still work.
