CVE-2025-39593 Overview
CVE-2025-39593 is a Cross-Site Request Forgery (CSRF) vulnerability affecting the EverAccounting wp-ever-accounting plugin for WordPress. The flaw exists in all versions up to and including 2.1.5. An attacker can trick an authenticated user into submitting a forged request that performs unintended state-changing actions within the plugin. The vulnerability is tracked under CWE-352 and requires user interaction over the network to exploit.
Critical Impact
Successful exploitation allows attackers to perform unauthorized actions in the context of an authenticated WordPress user, potentially modifying accounting data managed by the plugin.
Affected Products
- EverAccounting Ever Accounting plugin (wp-ever-accounting)
- All versions from n/a through 2.1.5
- WordPress installations with the vulnerable plugin active

Technical Details for CVE-2025-39593
Vulnerability Analysis
The Ever Accounting plugin fails to validate the origin or authenticity of state-changing HTTP requests. WordPress plugins typically use nonces to prevent CSRF, but the affected handlers in wp-ever-accounting do not enforce these checks correctly. An attacker crafts a malicious page or link that triggers a request to the WordPress site while a privileged user is authenticated. The browser automatically attaches the user's session cookies, allowing the forged action to succeed.
The issue affects integrity of plugin-managed data. Confidentiality and availability impacts are not indicated, since the attacker cannot directly read sensitive data or disrupt service through this class of flaw.
Root Cause
The root cause is missing or improper CSRF token validation on request handlers that modify plugin state. Without a verified nonce tied to the user session, the plugin accepts any request that carries valid authentication cookies, regardless of origin.
Attack Vector
Exploitation occurs over the network and requires user interaction. An attacker delivers a crafted link or embedded resource, often through phishing or a compromised third-party site. When an authenticated WordPress user with sufficient privileges visits the attacker-controlled content, their browser submits the forged request to the vulnerable endpoint. The plugin processes the request as legitimate.
No verified proof-of-concept code is publicly indexed. See the Patchstack advisory for additional technical context.
Detection Methods for CVE-2025-39593
Indicators of Compromise
- Unexpected changes to accounting records, transactions, or plugin settings managed by wp-ever-accounting
- HTTP POST or GET requests to plugin endpoints containing Referer headers pointing to external, untrusted domains
- Administrative actions logged from user sessions immediately after visits to unrelated external sites
Detection Strategies
- Review WordPress access logs for state-changing requests to wp-ever-accounting endpoints that lack a valid _wpnonce parameter
- Correlate authenticated administrator browsing activity with subsequent plugin modifications
- Enable WordPress audit logging plugins to track create, update, and delete operations within the accounting plugin
Monitoring Recommendations
- Alert on HTTP referers to plugin admin actions that originate outside the WordPress site domain
- Monitor for anomalous spikes in plugin database write operations tied to administrator accounts
- Track plugin version inventory across managed WordPress sites to confirm patched versions above 2.1.5 are deployed
How to Mitigate CVE-2025-39593
Immediate Actions Required
- Update the Ever Accounting plugin to a version newer than 2.1.5 as soon as a patched release is available from the vendor
- Restrict administrative access to trusted networks and require multi-factor authentication for WordPress admin accounts
- Instruct administrators to log out of the WordPress admin panel when not in active use
Patch Information
Refer to the Patchstack vulnerability database entry for the latest information on fixed versions and vendor updates. Apply the patched release through the WordPress plugin manager or via WP-CLI once available.
Workarounds
- Deactivate the wp-ever-accounting plugin until a patched version is installed if the plugin is not business-critical
- Deploy a Web Application Firewall (WAF) rule that blocks state-changing requests to plugin endpoints missing a valid nonce parameter
- Enforce SameSite=Strict or SameSite=Lax cookie attributes on WordPress session cookies to reduce cross-origin request risk
# Example WP-CLI commands to inventory and update the plugin
wp plugin list --name=wp-ever-accounting --fields=name,version,status
wp plugin update wp-ever-accounting
