CVE-2025-49292 Overview
CVE-2025-49292 affects the Cozmoslabs Profile Builder plugin for WordPress. The vulnerability is an Improper Validation of Specified Quantity in Input weakness [CWE-1284] that enables content spoofing and phishing attacks. All Profile Builder versions up to and including 3.13.8 are affected. Exploitation requires user interaction over the network and results in low-impact integrity compromise. The flaw allows attackers to craft URLs or requests that render manipulated content within the plugin, tricking users into trusting spoofed information.
Critical Impact
Attackers can inject spoofed content into Profile Builder pages to conduct phishing campaigns against WordPress site visitors and users.
Affected Products
- Cozmoslabs Profile Builder plugin for WordPress
- Profile Builder versions through 3.13.8
- WordPress sites using vulnerable Profile Builder installations

Technical Details for CVE-2025-49292
Vulnerability Analysis
The vulnerability stems from improper validation of input quantity within the Profile Builder plugin. The plugin fails to properly restrict or sanitize specific input parameters before reflecting them into user-facing content. An attacker can craft a URL containing manipulated parameters and deliver it to a victim. When the victim clicks the link, the plugin renders attacker-controlled text as if it were legitimate site content. This creates a content spoofing primitive suitable for phishing attacks against site users.
Exploitation requires user interaction (UI:R) and does not require authentication. The impact is limited to integrity (I:L) because the attacker cannot execute code or exfiltrate confidential data directly. However, spoofed pages can trick users into disclosing credentials or clicking secondary attacker-controlled links.
Root Cause
The root cause is classified under [CWE-1284] Improper Validation of Specified Quantity in Input. The plugin accepts input without correctly validating expected value ranges, formats, or lengths. This missing validation allows attackers to inject arbitrary content that the plugin subsequently displays as trusted output.
Attack Vector
The attack proceeds over the network. An attacker crafts a malicious URL targeting a Profile Builder endpoint on a vulnerable WordPress site. The attacker distributes the URL through email, social media, or messaging platforms. When a victim opens the link, the plugin renders the injected content within the legitimate site context. The spoofed page can impersonate login prompts, security notices, or account messages to harvest credentials or redirect users to attacker infrastructure. Full technical details are available in the Patchstack WordPress Vulnerability advisory.
Detection Methods for CVE-2025-49292
Indicators of Compromise
- Unexpected query string parameters on Profile Builder plugin endpoints containing HTML entities, unusual encoding, or suspicious text fragments.
- Referrer logs showing traffic from external phishing domains landing on Profile Builder pages.
- User reports of unexpected login prompts or notices appearing on account-related pages.
Detection Strategies
- Inventory all WordPress installations and identify sites running Profile Builder version 3.13.8 or earlier.
- Review web server access logs for requests to Profile Builder URLs containing anomalous parameter values or long input strings.
- Deploy web application firewall rules to inspect parameters submitted to Profile Builder endpoints for suspicious content.
Monitoring Recommendations
- Enable request logging on WordPress sites and forward logs to a centralized SIEM for parameter analysis.
- Track outbound clicks from Profile Builder pages that redirect users to external domains.
- Monitor user account activity for anomalous credential resets or login attempts following campaign windows.
How to Mitigate CVE-2025-49292
Immediate Actions Required
- Update the Cozmoslabs Profile Builder plugin to a version later than 3.13.8 as soon as the vendor publishes a fix.
- Audit WordPress plugin inventories and identify all sites running affected Profile Builder versions.
- Educate users and administrators about phishing links that abuse legitimate site domains.
Patch Information
Refer to the Patchstack WordPress Vulnerability advisory for the vendor patch and remediation guidance. Apply the fixed release through the WordPress plugin dashboard or by deploying the updated plugin package.
Workarounds
- Restrict access to Profile Builder pages through firewall rules or authentication requirements until patching is complete.
- Deploy WAF signatures that block requests containing suspicious payloads in Profile Builder parameters.
- Temporarily disable the Profile Builder plugin on sites that do not require its functionality.
