CVE-2026-1296

Frontend Post Submission Manager Lite <= 1.2.7 - Unauthenticated Open Redirect via 'requested_page' Parameter

Published Feb 18, 2026 CVSS 3.1 · 6.1 Medium EPSS < 1% KEV · Not listed

Description

The Frontend Post Submission Manager Lite plugin for WordPress is vulnerable to Open Redirection in all versions up to, and including, 1.2.7 due to insufficient validation on the 'requested_page' POST parameter in the verify_username_password function. This makes it possible for unauthenticated attackers to redirect users to potentially malicious sites if they can successfully trick them into performing an action such as clicking on a link.

Analysis

Technical impact

The Frontend Post Submission Manager Lite plugin for WordPress allows attackers to craft a request with a malicious 'requested_page' parameter, causing users who interact with the plugin to be redirected to arbitrary URLs. This opens the door to phishing, malware delivery, or other social-engineering attacks. The flaw is classified as a CWE‑601 Weakness in Input Validation.

Affected Systems

WordPress sites installing the Frontend Post Submission Manager Lite plugin, version 1.2.7 or earlier.

Risk and Exploitability

The CVSS score of 6.1 indicates a moderate severity and the EPSS score of less than 1 % suggests a low probability of automated exploitation. The vulnerability is not currently listed in the CISA KEV catalog. Attackers would need to entice a user to interact with the plugin – for example, by sending a link that forces the plugin to process the request – but no authentication is required, making the threat realistic on sites where the plugin is active.

OpenCVE Recommended Actions

Upgrade the Frontend Post Submission Manager Lite plugin to the latest release, which removes the vulnerable code.
If upgrade is not possible immediately, implement server-side validation that accepts only known safe URLs for the 'requested_page' parameter, effectively blocking arbitrary redirects.
Deploy a security plugin or web application firewall rule that detects and blocks open redirect patterns in plugin requests to mitigate the risk while a permanent fix is applied.
