CVE-2025-22563 Overview
CVE-2025-22563 is a Cross-Site Request Forgery (CSRF) vulnerability in the faaiq Pretty Url WordPress plugin (pretty-url). The flaw affects all versions up to and including 1.5.5. An attacker can trick an authenticated administrator into submitting a forged request that performs unwanted state-changing actions in the plugin. The issue is categorized under CWE-352 and requires user interaction to succeed. According to Patchstack's advisory, exploitation relies on victims visiting a malicious page while authenticated to a vulnerable WordPress site.
Critical Impact
Successful exploitation allows attackers to modify Pretty Url plugin settings on behalf of an authenticated administrator, leading to limited integrity impact on affected WordPress installations.
Affected Products
- faaiq Pretty Url plugin for WordPress
- Pretty Url versions from n/a through 1.5.5
- WordPress deployments running the vulnerable pretty-url plugin

Technical Details for CVE-2025-22563
Vulnerability Analysis
The vulnerability is a classic Cross-Site Request Forgery weakness in the Pretty Url plugin's request-handling logic. State-changing endpoints in the plugin do not properly validate that requests originate from a legitimate, intentional user action. WordPress plugins typically defend against this class of attack using nonces generated by wp_create_nonce() and validated via check_admin_referer() or wp_verify_nonce(). When these controls are missing or improperly implemented, an attacker can craft a page or link that, once visited by an authenticated user, silently submits a request to the target WordPress site.
The scope of the vulnerability is limited to actions permitted to the victim's session. In practice, most impactful exploitation targets an authenticated administrator, tricking them into modifying plugin configuration. Because the flaw requires user interaction, exploitation depends on social engineering such as phishing links or attacker-controlled web pages.
Root Cause
The root cause is the absence or improper validation of anti-CSRF tokens on request handlers exposed by the plugin. Without a per-request nonce tied to the user's session, the application accepts forged requests carrying only the session cookie, which the browser attaches automatically to cross-origin submissions.
Attack Vector
Exploitation occurs over the network. An attacker hosts a malicious HTML page containing an auto-submitting form or crafted image tag pointing to a Pretty Url plugin endpoint. When an authenticated WordPress administrator visits the page, the browser sends the request along with valid authentication cookies. The plugin processes the request as legitimate and applies the change. Details are documented in the Patchstack CSRF Vulnerability Advisory.
Detection Methods for CVE-2025-22563
Indicators of Compromise
- Unexpected modifications to Pretty Url plugin settings in the WordPress admin panel.
- Administrator-initiated POST requests to pretty-url endpoints with Referer headers pointing to external, untrusted domains.
- WordPress audit log entries showing plugin configuration changes at times inconsistent with normal administrator activity.
Detection Strategies
- Inspect web server access logs for POST requests to pretty-url administrative endpoints originating from cross-origin Referer values.
- Enable a WordPress activity or audit logging plugin to record all plugin setting changes with user, IP, and timestamp context.
- Deploy a Web Application Firewall (WAF) rule that flags state-changing requests to pretty-url handlers missing a valid nonce parameter.
Monitoring Recommendations
- Alert on administrator sessions performing plugin setting changes shortly after visiting external links or opening email content.
- Correlate WordPress audit logs with endpoint telemetry to identify browser-driven request forgery patterns.
- Track version inventory of the pretty-url plugin across managed WordPress sites and flag any instance at 1.5.5 or earlier.
How to Mitigate CVE-2025-22563
Immediate Actions Required
- Update the Pretty Url plugin to a version newer than 1.5.5 once the vendor publishes a fix, per the Patchstack advisory.
- Audit Pretty Url plugin settings for unauthorized changes and revert any suspicious modifications.
- Force re-authentication for WordPress administrators and rotate active session tokens.
Patch Information
At the time of NVD publication, no fixed version is listed beyond 1.5.5. Administrators should monitor the plugin's WordPress.org page and the Patchstack advisory for a patched release. If no vendor patch is available, deactivate and remove the plugin until a fix is issued.
Workarounds
- Deactivate the pretty-url plugin until a patched release is available.
- Restrict WordPress admin access using IP allow-listing at the web server or WAF layer.
- Enforce SameSite=Lax or SameSite=Strict cookie attributes on WordPress authentication cookies to reduce cross-site request risk.
- Train administrators to avoid clicking untrusted links while logged into WordPress admin sessions.
# Configuration example: disable the vulnerable plugin via WP-CLI
wp plugin deactivate pretty-url
wp plugin delete pretty-url
# Verify plugin is no longer installed
wp plugin list --name=pretty-url
