Foxit foxit.com: Hard-coded API token in website JavaScript
Summary
The Foxit official website embeds a third-party API token in its JavaScript code, so any visitor can read it. An attacker who obtains the token can submit fake user behavior data and distort Foxit's data statistics. The Foxit bulletin states the token is used to submit user behavior data; the CNA record rates the impact as information disclosure with high confidentiality impact.
Affected
- Foxit official website foxit.com, before 2026-10-29 (according to the CNA record)
- Specific versions: Unknown.
- Foxit PDF Reader and Foxit PDF Editor desktop products are not named as affected by the website bulletin.
Fixed in
- Foxit's bulletin of 29 October 2026 reports the issue as addressed on the website.
- Specific fixed version: Unknown.
- Whether the exposed token was rotated or removed: Unknown.
Workaround
- No vendor workaround documented. Customers cannot patch Foxit's own website.
Exploitation
- Exploitation in the wild: Unknown. No public proof of concept found.
- CISA SSVC assessment: Exploitation none, automatable yes, technical impact partial.
- EPSS 0.35 % (percentile 28).
Our recommendation
- If your organisation uses Foxit online services or API integrations, ask Foxit whether any credentials issued to you are affected.
- Rotate any Foxit-related API credentials if in doubt.
- Review access logs for unexpected activity.
- Desktop-only environments: no direct action needed beyond keeping Foxit PDF Reader and Editor up to date.
