Security readout for executives and security teams
Plain-English summary
CVE-2025-31578 is a reflected cross-site scripting issue in the WordPress Fonts Manager | Custom Fonts plugin through version 1.2. An attacker could trick a user into opening a crafted link and cause script to run in that user’s browser. The source bundle does not show active exploitation or a named fixed version.
Executive priority
Prioritize this for WordPress environments where the plugin is installed, especially public-facing sites with many administrators or editors. Business urgency is high for confirmed deployments, but lower for environments without the plugin and because active exploitation is not evidenced in the supplied sources.
Technical view
The CVE describes CWE-79 improper input neutralization during webpage generation in package fonts-manager-custom-fonts. CVSS 3.1 is 7.1 high: network reachable, low complexity, no privileges required, user interaction required, and changed scope with low confidentiality, integrity, and availability impact.
Likely exposure
Exposure is limited to WordPress sites running Wisdomlogix Solutions Pvt. Ltd. Fonts Manager | Custom Fonts at version 1.2 or earlier. The affected version data in the bundle is inconsistent, so teams should verify the installed plugin slug and exact version locally.
Exploitation context
The bundle marks KEV as false and provides no cited evidence of active exploitation. The CVSS vector indicates exploitation requires user interaction, likely through a crafted request or link, but no exploit steps or confirmed public exploitation are included in the provided sources.
Researcher notes
Key gaps are patch availability, vulnerable parameter details, and exploit-in-the-wild evidence. The record supports reflected XSS only, with CVSS PR:N/UI:R/S:C. Avoid assuming stored XSS, unauthenticated account takeover, or a fixed version unless confirmed by vendor or Patchstack updates.
Mitigation direction
- Inventory WordPress sites for the fonts-manager-custom-fonts plugin.
- Verify whether installed versions are 1.2 or earlier.
- Check Patchstack and vendor guidance for a fixed version or official mitigation.
- Disable the plugin where it is nonessential and risk acceptance is not appropriate.
- Increase monitoring for suspicious WordPress requests involving the plugin.
Validation and detection
- Confirm plugin slug, vendor, and version from WordPress inventory.
- Compare findings against the CVE description and Patchstack entry.
- Review WAF and web logs for unusual plugin-related requests.
- Validate any remediation in staging before production rollout.
- Document sites where the plugin is absent, disabled, or remediated.

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.
