CVE-2026-111419 in Foxit
Summary
by MITRE • 10/29/2026
A sensitive information exposure vulnerability exists on the Foxit official website because JavaScript code contains third-party authorization information. This may allow unauthorized parties to obtain or misuse the exposed credentials.

The disclosed vulnerability represents a classic instance of client-side credential leakage, specifically categorized under CWE-798: Use of Hard-coded Credentials and CWE-200: Exposure of Sensitive Information to an Unauthorized Actor. This flaw resides within the JavaScript source code hosted on the Foxit official website, where third-party authorization tokens or API keys are embedded directly into the script files accessible by any user visiting the site. In modern web development, it is a fundamental security principle that sensitive authentication data should never be exposed in client-side code because browsers download and execute these scripts for all visitors, making them trivially viewable through standard developer tools or network inspection utilities. The presence of such credentials suggests either an oversight during deployment where environment-specific secrets were not properly excluded from the build process, or a misconfiguration that inadvertently published internal development keys to production assets.
From a technical perspective, this vulnerability allows any individual with basic web browsing capabilities and knowledge of browser developer tools to extract the exposed authorization information. Once obtained, these credentials can be used by malicious actors to impersonate legitimate services, access restricted APIs, consume third-party service quotas leading to financial loss for the organization, or potentially escalate privileges if the permissions associated with those tokens are overly broad. This type of exposure is particularly dangerous because it bypasses server-side authentication controls entirely; the attacker does not need to exploit a logic flaw in the application itself but rather leverages the misconfiguration of its static assets. The impact extends beyond immediate data theft, as compromised third-party keys can serve as an entry point for further attacks against integrated services or supply chain components linked to Foxit's infrastructure.
This incident aligns with several techniques documented in the MITRE ATT&CK framework, particularly T1539: Steal Web Session Cookie and T1078: Valid Accounts, depending on how the exposed credentials are utilized by attackers. It also reflects common pitfalls described in OWASP guidelines regarding sensitive data exposure, emphasizing that security controls must be implemented at multiple layers rather than relying solely on server-side validation while exposing secrets to the client. The operational impact includes potential reputational damage and loss of trust from customers who expect their vendor to maintain rigorous security hygiene across all digital touchpoints, including public-facing marketing sites.
To mitigate this vulnerability, immediate remediation requires removing all hardcoded credentials from production JavaScript files and implementing a robust secret management strategy using dedicated vaults or environment variable injection systems that do not expose secrets in static assets. Developers should conduct thorough code reviews focusing on build pipelines to ensure that configuration files containing sensitive data are excluded from the final bundle through proper filtering mechanisms such as webpack plugins or similar tools. Additionally, rotating all potentially compromised third-party keys is critical to invalidate any tokens already harvested by attackers during the window of exposure. Long-term improvements involve adopting automated security scanning in CI/CD pipelines to detect hardcoded secrets before deployment and enforcing strict access controls on source code repositories to prevent accidental commits of sensitive configuration data.
