Security readout for executives and security teams
Plain-English summary
CVE-2025-49433 is a medium-severity cross-site scripting issue in the WordPress Supermalink plugin up to version 1.1. It could let an authenticated attacker influence what a user’s browser runs after user interaction. The available sources do not show active exploitation or a named fixed version.
Executive priority
Treat this as a moderate-priority WordPress plugin issue. It is not currently supported by evidence of active exploitation, but it should be handled in normal vulnerability remediation cycles, faster for public sites or environments with many WordPress users.
Technical view
The issue is classified as CWE-79 DOM-based XSS in ThanhD Supermalink. The CVSS 3.1 score is 6.5 with network attack vector, low complexity, low privileges required, user interaction required, and changed scope. Public technical detail is limited in the supplied sources.
Likely exposure
Exposure is likely limited to WordPress sites running the Supermalink plugin with versions through 1.1. The source bundle has no CPEs and limited affected-version metadata, so validate by plugin slug, installed version, and vendor record rather than asset scanners alone.
Exploitation context
The provided data does not indicate known active exploitation, and the CVE is not listed as KEV. The CVSS vector implies exploitation requires low privileges and user interaction, reducing broad automated risk but still creating concern for sites with untrusted contributors or complex admin workflows.
Researcher notes
Evidence is sparse beyond the CVE metadata and Patchstack entry. Avoid assuming exploitability details, affected endpoints, or a fixed version from the supplied bundle. The main validation challenge is reliable plugin identification because CPE data is absent.
Mitigation direction
- Inventory WordPress sites for the Supermalink plugin.
- Check vendor or Patchstack guidance for a fixed release.
- Disable or remove the plugin if it is not required.
- Restrict WordPress accounts that can reach affected plugin functionality.
- Prioritize remediation on public or multi-user WordPress sites.
Validation and detection
- Confirm installed plugin slug and version on each WordPress site.
- Verify whether any instance runs Supermalink version 1.1 or earlier.
- Review vendor and Patchstack records for updated remediation guidance.
- After mitigation, confirm the plugin is updated, disabled, or removed.
- Document exceptions where the plugin remains installed.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
