WPLP Cookie Consent stores public input as executable admin-side JavaScript on multisite
WPLP Cookie Consent before 4.4.4 accepts a value at a public endpoint, logs it and later emits it on an administrative screen without JavaScript-context escaping. An unauthenticated attacker can store script that executes in an administrator's session when the administrator interacts with the logged entry. Only multisite installations are affected. The export does not identify the endpoint, input field, logging function or required interaction.

4.4.4- Published
- Sep 17, 2026
This CVE was published Sep 17, 2026 and is one of 22 known issues for this plugin.
Update, patch or deactivate.
Update WPLP Cookie Consent to 4.4.4 or later. Escape or safely serialize logged values for the JavaScript context and present logs as untrusted data. Remove malicious entries before administrators interact with them; ordinary HTML escaping is not sufficient for JavaScript output.
A safe version is available, so updating to that version or later is the preferred remediation. If an immediate update is not practical, consider a targeted application patch or temporarily restricting the affected functionality.
Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.
Technical description
The WPLP Cookie Consent WordPress plugin before 4.4.4 does not escape a value submitted through a public endpoint for the JavaScript context it is later output in on an administrative screen, allowing unauthenticated users to run arbitrary JavaScript in the session of an administrator who interacts with the logged entry. Only multisite installations are affected.
