Overview

The MW WP Form plugin for WordPress is vulnerable to stored XSS via the post_id parameter. Unauthenticated attackers can inject scripts that run for any user viewing the page. This allows malicious code execution on site visitors.

Description

The MW WP Form plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'post_id' parameter in all versions up to, and including, 5.1.7 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The CSRF gate protecting form submission (MW_WP_Form_Csrf) is bypassable by any unauthenticated visitor who first loads the public form page to obtain a valid double-submit cookie, leaving no effective barrier to storing malicious payloads.

Impact

Confidentiality: injected scripts may exfiltrate user data. Integrity: malicious scripts can alter page content. Availability: not directly affected. Defenders: site administrators and users are impacted.

Remediation

Update MW WP Form to version 5.1.8 or later. If update is not possible, disable the plugin or block the post_id parameter using a web application firewall. Ensure proper input sanitization and output escaping. Use security plugins to detect and block XSS payloads.

Risk context

High severity (CVSS 7.2) but low EPSS (0.00259) indicates a low likelihood of exploitation. Defenders should patch promptly to mitigate potential XSS attacks.

CVE-2026-104912

MISP before v2.5.48 has an authorization flaw in correlation handling during attribute searches. Correlated attributes and events can be authorized using a stale distribution snapshot instead of the live event access control list. This matters because restricted or unpublished events may remain visible to authenticated users who no longer have permission.

CVE-2026-94544

CVE-2026-94544 exposes a cache sharing flaw in Next.js 16.3.0‑16.3.8 that allows unauthenticated users to see unpublished draft content or see published content in draft mode. The vulnerability arises when Cache Components or experimental.useCache are enabled and cached functions return draft‑dependent data. It can lead to accidental disclosure of sensitive content on public sites.

CVE-2026-92977

The Real Cookie Banner: GDPR & ePrivacy Cookie Consent plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Comment in all versions up to, and including, 5.3.5 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Malicious script payloads placed in the title attribute of an anchor tag survive WordPress's comment kses filter at save time, as the payload is only promoted to executable HTML attributes when the plugin's page-wide regex strips the closing quote delimiter at render time; exploitability is therefore subject to the standard comment moderation workflow before the comment is publicly displayed.

CVE-2026-101160

The WP Ultimate Review WordPress plugin before 2.4.4 does not validate that a submitted review rating is numeric before storing it and later using it in numeric operations when rendering reviews, allowing unauthenticated users to make the reviewed content fail with a fatal error for all visitors until the review is removed (a persistent denial of service), when user reviews are enabled.
