CVE-2026-1296: Frontend Post Submission Manager Lite <= 1.2.7 - Open Redirect

id: CVE-2026-1296

info:
  name: Frontend Post Submission Manager Lite <= 1.2.7 - Open Redirect
  author: Shivam Kamboj
  severity: medium
  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.
  impact: |
    Unauthenticated attackers can redirect users to malicious sites, potentially leading to phishing or malware exposure.
  remediation: |
    Update to a version later than 1.2.7 or the latest available version.
