CVE-2025-49419: Foxit eSign Information Disclosure Flaw

CVE-2025-49419 Overview

CVE-2025-49419 is an information disclosure vulnerability in the Foxit eSign for WordPress plugin (esign-genie-for-wp) developed by esigngenie. The flaw affects all plugin versions up to and including 2.0.3. An authenticated attacker with high privileges can retrieve embedded sensitive data through an unauthorized control sphere, mapped to [CWE-497]. The vulnerability is exploitable over the network without user interaction. Patchstack published the advisory tracking this issue in the WordPress plugin ecosystem.

Critical Impact
An authenticated attacker with high privileges can extract sensitive system information embedded in the plugin, potentially exposing API credentials, configuration data, or integration secrets used by the eSign workflow.

Affected Products

Foxit eSign for WordPress plugin (esign-genie-for-wp)
All versions from initial release through 2.0.3
WordPress sites integrating Foxit eSign document signing workflows

Technical Details for CVE-2025-49419

Vulnerability Analysis

The vulnerability falls under [CWE-497] — Exposure of Sensitive System Information to an Unauthorized Control Sphere. The Foxit eSign for WordPress plugin fails to properly restrict access to embedded sensitive data within its administrative or integration surface. An attacker who already holds high-privilege access to the WordPress installation can retrieve information that should remain isolated from the caller's control sphere.

While the required privilege level limits opportunistic exploitation, the exposure has direct consequences in multi-administrator environments and hosted WordPress deployments where trust boundaries between operators are enforced by the application layer.

Root Cause

The root cause is insufficient separation between sensitive plugin data and the interfaces exposed to authenticated users. The plugin embeds sensitive system information — likely tied to eSign API integration, tokens, or configuration — in locations reachable through normal plugin endpoints. There is no additional authorization boundary preventing retrieval by callers who should not have access to that data.

Attack Vector

Exploitation requires network access to the WordPress site and authenticated high-privilege credentials. The attacker interacts with plugin functionality that returns or renders the embedded sensitive data. No user interaction is required, and the attack does not depend on chained vulnerabilities. Confidentiality is the primary impact; integrity is affected to a limited degree, and availability is not impacted.

No public proof-of-concept exploit code is available. Refer to the Patchstack Vulnerability Report for advisory details.

Detection Methods for CVE-2025-49419

Indicators of Compromise

Unexpected requests from authenticated administrator sessions to esign-genie-for-wp plugin endpoints outside normal signing workflows
WordPress access logs showing repeated queries against plugin settings or integration handlers by low-activity admin accounts
Outbound calls to unknown eSign API endpoints originating shortly after suspicious plugin access

Detection Strategies

Audit WordPress user accounts with administrator or equivalent roles and review recent activity for anomalous plugin access
Enable WordPress activity logging to capture plugin configuration reads and administrative API interactions
Correlate web server logs with plugin route access patterns to identify data retrieval sequences inconsistent with normal use

Monitoring Recommendations

Monitor for administrative access from unfamiliar IP addresses or during off-hours
Track changes to plugin configuration and integration credentials
Alert on programmatic (non-browser) User-Agent strings accessing plugin admin endpoints

How to Mitigate CVE-2025-49419

Immediate Actions Required

Identify all WordPress installations running Foxit eSign for WordPress version 2.0.3 or earlier
Restrict administrator-level access to the minimum set of trusted users while patching
Rotate any eSign API keys, tokens, or integration credentials configured within the plugin
Review WordPress audit logs for prior unauthorized access to plugin data

Patch Information

At the time of publication, verify the latest available version of the esign-genie-for-wp plugin through the WordPress plugin repository and vendor advisories. Consult the Patchstack Vulnerability Report for updated fix information and upgrade guidance.

Workarounds

Temporarily deactivate the esign-genie-for-wp plugin if a patched version is not yet available
Enforce multi-factor authentication for all WordPress administrator accounts to reduce the risk of credential compromise
Restrict access to the WordPress admin interface using IP allowlists at the web server or WAF layer
Apply the principle of least privilege by reviewing custom roles that may inherit plugin access

bash

# Example: restrict wp-admin access by IP using Apache .htaccess
<Directory "/var/www/html/wp-admin">
    Require ip 203.0.113.0/24
    Require ip 198.51.100.42
</Directory>

# Example: disable the plugin via WP-CLI until patched
wp plugin deactivate esign-genie-for-wp
