Security readout for executives and security teams
Plain-English summary
CVE-2025-46442 affects the WordPress Loan Calculator plugin, package repayment-calculator, through version 1.3. A malicious site could abuse a logged-in WordPress user’s browser to save harmful script into the site. That script could later run for site users or administrators, risking data exposure, content changes, and operational disruption.
Executive priority
Treat this as high priority for WordPress sites using the plugin. It is not proven exploited in the supplied sources, but stored XSS on public websites can affect trust, visitor safety, and administrative control.
Technical view
The issue is a CSRF vulnerability leading to stored XSS in Casey Johnson’s Loan Calculator plugin for WordPress. The CVSS 3.1 score is 7.1: network-reachable, low complexity, no attacker privileges, user interaction required, changed scope, and low confidentiality, integrity, and availability impact.
Likely exposure
Exposure is limited to WordPress installations running Loan Calculator, package repayment-calculator, through version 1.3. The source bundle does not identify affected configurations beyond the plugin/version range.
Exploitation context
The CVE is not listed as KEV in the supplied data, and the provided sources do not state active exploitation. The attack model requires user interaction, consistent with CSRF, and can result in stored XSS.
Researcher notes
Evidence is narrow: the bundle identifies CSRF to stored XSS, affected versions through 1.3, CVSS 7.1, CWE-352, and one Patchstack reference. It does not provide exploit detail, fixed version, vulnerable endpoint, or confirmed exploitation.
Mitigation direction
- Inventory WordPress sites for repayment-calculator or Loan Calculator plugin installations.
- Prioritize sites running plugin version 1.3 or earlier.
- Check Patchstack and vendor guidance for a confirmed fixed version or mitigation.
- Disable or remove the plugin if no trusted fix is available.
- Limit administrator sessions and review WordPress hardening controls.
Validation and detection
- Confirm plugin presence and version across production WordPress sites.
- Review administrative pages for unexpected stored script or injected markup.
- Check recent content and plugin settings changes for unauthorized modifications.
- Review security logs for suspicious admin-side requests or redirects.
- Track CVE and Patchstack updates for fixed-version confirmation.

Cross-Site Request Forgery (CSRF)
Cross-Site Request Forgery (CSRF) represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
