CVE-2025-7813
📋 TL;DR
This vulnerability allows unauthenticated attackers to perform Server-Side Request Forgery (SSRF) attacks through the Eventin WordPress plugin. Attackers can make arbitrary web requests from the vulnerable server, potentially accessing internal services and sensitive data. All WordPress sites using Eventin plugin versions up to 4.0.37 are affected.
💻 Affected Systems
- Eventin WordPress plugin (Event Manager, Events Calendar, Tickets, Registrations)

⚠️ Risk & Real-World Impact
Worst Case
Attackers could access internal services, read sensitive files, perform port scanning of internal networks, or interact with cloud metadata services to obtain credentials.
Likely Case
Attackers will scan internal networks, access internal web applications, and potentially retrieve sensitive information from services that shouldn't be publicly accessible.
If Mitigated
With proper network segmentation and internal service authentication, impact is limited to information disclosure from services that accept unauthenticated requests.
🎯 Exploit Status
SSRF vulnerabilities are commonly exploited and weaponized quickly due to their utility in internal network reconnaissance.

🔍 How to Verify
Check if Vulnerable:
Check WordPress admin panel > Plugins > Eventin version. If version is 4.0.37 or lower, you are vulnerable.Check Version:
wp plugin list --name=wp-event-solution --field=versionVerify Fix Applied:
Verify plugin version shows 4.0.38 or higher in WordPress admin panel.📡 Detection & Monitoring
Log Indicators:
- Unusual outbound HTTP requests from web server to internal IPs
- Requests to /wp-admin/admin-ajax.php with 'action=eventin_proxy_image' parameter containing URLs
Network Indicators:
- Web server making HTTP requests to internal IP ranges (10.x.x.x, 172.16.x.x, 192.168.x.x)
- Unusual port scanning patterns originating from web server
SIEM Query:
source="web_server_logs" AND (uri_path="/wp-admin/admin-ajax.php" AND query_string="*action=eventin_proxy_image*" AND NOT dest_ip IN [public_ip_ranges])🔗 References
