CVE-2025-26945 Overview
CVE-2025-26945 is a stored cross-site scripting (XSS) vulnerability in the bPlugins Info Cards WordPress plugin. The flaw stems from improper neutralization of user input during web page generation [CWE-79]. It affects all versions of Info Cards up to and including 1.0.5.
An authenticated attacker with low privileges can inject malicious script content that persists in the WordPress database. The payload executes in the browser of any user who views the affected page. Because the vulnerability has a changed scope, injected scripts can impact resources beyond the plugin itself.
Critical Impact
Stored script payloads execute in site visitors' browsers, enabling session theft, administrative action hijacking, and content defacement on affected WordPress sites.
Affected Products
- bPlugins Info Cards plugin for WordPress
- Versions from n/a through 1.0.5
- WordPress sites with the info-cards plugin installed and active

Technical Details for CVE-2025-26945
Vulnerability Analysis
The Info Cards plugin fails to properly sanitize and encode user-supplied input before rendering it within generated WordPress pages. An authenticated contributor-level or higher user can submit script content through plugin input fields. The content is stored in the database and later rendered to end users without adequate escaping.
When another authenticated user, such as an administrator, loads a page containing the injected payload, the script executes within the context of their session. This allows the attacker to perform actions on behalf of the victim, exfiltrate cookies, or deliver follow-on payloads. The changed scope indicates impact extends beyond the vulnerable component.
Root Cause
The root cause is the absence of appropriate output encoding and input sanitization in the plugin's rendering logic. WordPress provides helper functions such as esc_html(), esc_attr(), and wp_kses_post() for safe rendering, but the affected code paths in Info Cards versions through 1.0.5 do not consistently apply them to attacker-controlled fields.
Attack Vector
Exploitation requires network access to the WordPress site, low-privileged authenticated access, and user interaction from the victim who views the injected content. The attacker configures an Info Cards entry containing a JavaScript payload. The payload is persisted and later served to any user that renders the affected page or shortcode output.

Detection Methods for CVE-2025-26945
Indicators of Compromise
- Unexpected <script> tags, on* event handlers, or javascript: URIs stored within Info Cards plugin database entries
- Outbound requests from administrator browser sessions to unfamiliar external domains after viewing plugin-rendered pages
- New or modified WordPress administrator accounts created shortly after an admin visited a page containing Info Cards content
Detection Strategies
- Query the wp_posts and wp_postmeta tables for Info Cards entries containing HTML event attributes or <script> fragments
- Review web server access logs for POST requests to admin-ajax.php or Info Cards editor endpoints submitted by low-privileged accounts
- Inspect Content Security Policy (CSP) violation reports for inline script executions originating on pages rendering Info Cards content
Monitoring Recommendations
- Monitor WordPress audit logs for content creation and editing activity by contributor and author roles
- Track plugin version inventory to confirm Info Cards instances are updated beyond version 1.0.5 once a fix is published
- Alert on administrator session anomalies, including unexpected privilege changes or new user registrations following page views
How to Mitigate CVE-2025-26945
Immediate Actions Required
- Deactivate and remove the Info Cards plugin on all WordPress sites still running version 1.0.5 or earlier until a patched release is confirmed
- Audit existing Info Cards content for stored script payloads and remove any malicious entries
- Rotate credentials and session tokens for administrator accounts that may have viewed attacker-controlled pages
Patch Information
As of the last NVD update on 2026-06-17, no fixed version is listed in the advisory. Site owners should monitor the Patchstack advisory and the bPlugins vendor channels for a security release addressing CVE-2025-26945.
Workarounds
- Restrict contributor, author, and editor role assignments to trusted users only to limit who can submit plugin content
- Deploy a Web Application Firewall (WAF) with rules that block common XSS payload patterns in POST requests to WordPress editor endpoints
- Enforce a strict Content Security Policy that disallows inline scripts and limits script sources to trusted origins
# Example restrictive CSP header for Apache
Header always set Content-Security-Policy "default-src 'self'; script-src 'self'; object-src 'none'; base-uri 'self'; frame-ancestors 'self'"
