Security readout for executives and security teams
Plain-English summary
CVE-2026-25339 is a medium-severity data exposure issue in the WordPress Contact Form by WPForms plugin, affecting wpforms-lite through version 1.9.8.7. The issue may expose sensitive information embedded in sent data. It is not listed as actively exploited in the provided sources.
Executive priority
Handle as a near-term privacy and confidentiality issue for WordPress sites using WPForms Lite. Prioritize customer-facing or regulated-data forms first. There is no provided evidence of active exploitation, but the affected plugin is widely deployable and may expose sensitive submitted data.
Technical view
The CVE describes CWE-201: insertion of sensitive information into sent data. It affects Syed Balkhi Contact Form by WPForms / wpforms-lite through <= 1.9.8.7. CVSS 3.1 is 6.5: network-accessible, low complexity, no privileges required, user interaction required, high confidentiality impact, no integrity or availability impact.
Likely exposure
Exposure is most likely on WordPress sites running wpforms-lite at version 1.9.8.7 or earlier, especially where forms process personal, customer, or operational data. Public source detail is limited, so exact data types and affected configurations are not fully established.
Exploitation context
The CVSS vector indicates exploitation is network-accessible and low complexity, but requires user interaction. The provided bundle does not include proof-of-concept details, exploitation reports, or CISA KEV listing. Treat this as a confidentiality risk rather than confirmed active exploitation.
Researcher notes
Public detail is sparse. The record identifies CWE-201 and a confidentiality-only CVSS profile, but does not describe affected code paths, fixed version, exploit availability, or required configuration. Avoid assuming exploitation mechanics beyond the published CVSS and description.
Mitigation direction
- Inventory WordPress sites for the wpforms-lite plugin and installed version.
- Prioritize sites running wpforms-lite 1.9.8.7 or earlier.
- Check WPForms and Patchstack guidance for fixed versions or official mitigations.
- Update the plugin when a vendor-confirmed fixed release is available.
- Limit collection and transmission of sensitive data through affected forms where feasible.
- Review form notification settings for unintended sensitive data exposure.
Validation and detection
- Confirm whether each WordPress site has wpforms-lite installed.
- Record the plugin version and compare it with <= 1.9.8.7.
- Review form configurations that send emails or notifications.
- Check whether sensitive fields are embedded in sent form data.
- Review recent form submissions and notifications for unintended sensitive information.
- Document remediation status for each affected WordPress instance.

Insertion of Sensitive Information Into Sent Data
Insertion of Sensitive Information Into Sent Data represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
