Attack Vectors

This medium-severity vulnerability (CVSS 4.3) affects the Auto Post to Social Media from Social Champ WordPress plugin (also referred to as “SocialChamp with WordPress”) in versions up to and including 1.3.5.

The primary attack path is Cross-Site Request Forgery (CSRF): an unauthenticated attacker cannot change settings directly, but can potentially modify plugin settings if they can trick a logged-in WordPress administrator into performing an action such as clicking a crafted link or visiting a malicious page while authenticated to the admin dashboard.

Reference: CVE-2025-14846 and the public advisory from Wordfence.

Security Weakness

The issue is caused by missing nonce validation in the plugin function wpsc_settings_tab_menu. In WordPress, nonces are commonly used to confirm that a settings change request is intentional and initiated by an authorized user.

Without this validation, an attacker can attempt to submit a forged request that the administrator’s browser may “carry along” using the admin’s existing authenticated session—making it possible to change plugin settings even though the attacker is not logged in.

Remediation: Update Auto Post to Social Media from Social Champ to version 1.3.6 or any newer patched version.

Technical or Business Impacts

The confirmed impact is unauthorized modification of plugin settings (integrity impact is rated low in the CVSS vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N). Even a “settings-only” change can create business risk, especially for organizations that rely on automated social publishing as part of campaigns, announcements, or regulated communications.

Potential business impacts include brand and campaign disruption (automation misconfiguration that changes how or whether posts are published), operational overhead (time spent diagnosing unexpected posting behavior), and governance/compliance concerns if posting workflows are part of an approvals process and settings changes undermine expected controls.

Because CSRF relies on user interaction, the risk rises when admins are exposed to phishing, malicious ads, or lookalike “support” messages that entice clicks while they are logged into WordPress.

Similar Attacks

CSRF is a common pattern in web applications and CMS plugins because it targets human behavior (getting an authenticated user to click). For non-technical stakeholders, it can be helpful to review reputable walkthroughs that show how “click once” attacks can cause unintended changes:
