CVE-2025-31447: NertWorks Social Share Tools CSRF Flaw

CVE-2025-31447 Overview

CVE-2025-31447 is a Cross-Site Request Forgery (CSRF) vulnerability affecting the NertWorks All in One Social Share Tools WordPress plugin. The flaw impacts all versions up to and including 1.26. The weakness is classified under [CWE-352] and stems from missing or insufficient anti-CSRF protections on plugin-handled requests.

An attacker can craft a malicious web page or link that, when visited by an authenticated WordPress user, triggers unwanted state-changing actions on the target site. Exploitation requires user interaction but no privileges on the target site.

Critical Impact
Authenticated users who visit attacker-controlled content can be forced to execute plugin actions on their WordPress site, leading to limited integrity and availability impact on affected installations.

Affected Products

NertWorks All in One Social Share Tools plugin for WordPress
Plugin slug nertworks-all-in-one-social-share-tools
All versions from initial release through 1.26

Technical Details for CVE-2025-31447

Vulnerability Analysis

The vulnerability is a Cross-Site Request Forgery weakness in the nertworks-all-in-one-social-share-tools plugin. Requests that modify plugin state do not verify the origin or authenticity of the submission. As a result, a browser session belonging to an authenticated WordPress user can be abused to submit forged requests to the plugin's endpoints.

Exploitation requires the victim to be authenticated to the target WordPress site and to interact with attacker-controlled content, such as clicking a link or loading a page containing an auto-submitting form. The attacker never sees the response, but the request executes with the victim's session context.

The scope of impact is bounded to actions the plugin exposes. According to the CVSS metrics, the vulnerability produces limited integrity and availability effects with no confidentiality impact.

Root Cause

The root cause is the absence of proper CSRF countermeasures on plugin request handlers. WordPress plugins typically defend against CSRF using nonces generated with wp_create_nonce() and validated using check_admin_referer() or wp_verify_nonce(). In affected versions through 1.26, one or more plugin endpoints do not enforce this validation, allowing requests to succeed based solely on the victim's active session cookie.

Attack Vector

The attack is delivered over the network and requires user interaction. An attacker hosts a page containing a hidden form or image tag that issues a request to a vulnerable plugin endpoint on the target WordPress site. When an authenticated administrator or user visits the attacker's page, their browser automatically attaches session cookies to the forged request, and the plugin processes it as legitimate.

No authentication is required from the attacker, and no credentials are exposed. The exploitation surface is limited to state changes the plugin permits for the victim's role.

No public proof-of-concept code or verified exploit examples are available. See the Patchstack WordPress Vulnerability Report for advisory details.

Detection Methods for CVE-2025-31447

Indicators of Compromise

Unexpected changes to NertWorks All in One Social Share Tools plugin configuration or settings that no administrator recalls making.
WordPress access logs showing plugin endpoint requests with Referer headers pointing to external, untrusted domains.
Administrator sessions performing plugin actions immediately after visiting third-party sites or clicking external links.

Detection Strategies

Inspect web server access logs for POST requests targeting plugin handlers where the Referer is missing or does not match the site's own domain.
Correlate WordPress audit logs with browsing activity to identify state-changing actions that lack a preceding admin console navigation.
Scan installed WordPress plugins for version 1.26 or earlier of nertworks-all-in-one-social-share-tools using inventory tooling.

Monitoring Recommendations

Enable a WordPress activity logging plugin to record configuration changes with user, timestamp, and source IP.
Alert on plugin setting modifications performed outside normal administrative hours or from unusual IP ranges.
Monitor outbound HTTP referrers in browser telemetry for administrator workstations that access the WordPress admin panel.

How to Mitigate CVE-2025-31447

Immediate Actions Required

Identify all WordPress sites running nertworks-all-in-one-social-share-tools at version 1.26 or earlier.
Deactivate the plugin until a patched version is available if it is not actively required for site operations.
Instruct WordPress administrators to log out of admin sessions before browsing untrusted sites and to use a dedicated browser or profile for admin activity.

Patch Information

At the time of this writing, the advisory lists affected versions through <= 1.26. Site owners should consult the Patchstack advisory and the WordPress plugin repository for the latest patched release and apply the update as soon as it is available.

Workarounds

Deploy a web application firewall (WAF) rule that blocks state-changing requests to the plugin's endpoints when the Referer or Origin header does not match the site's own hostname.
Enforce SameSite=Lax or SameSite=Strict on WordPress authentication cookies to reduce cross-site request delivery.
Restrict WordPress administrative access by IP allowlist at the reverse proxy or WAF layer where feasible.
Require administrators to reauthenticate for sensitive actions using a session timeout policy shorter than the default.
