Atomic Edge analysis of CVE-2026-1614 (metadata-based):
This vulnerability is an authenticated stored cross-site scripting (XSS) flaw in the Rise Blocks – A Complete Gutenberg Page Builder WordPress plugin. The issue exists in the Site Identity block’s ‘logoTag’ attribute handling. Attackers with Contributor-level or higher permissions can inject malicious scripts into pages. These scripts execute when users view the compromised pages. The CVSS score of 6.4 reflects medium severity with network accessibility, low attack complexity, and scope change impact.

Atomic Edge research identifies the root cause as insufficient input sanitization and output escaping. The plugin fails to properly neutralize user-supplied input in the ‘logoTag’ attribute before storing it in the database. The plugin also fails to escape this data when outputting it during page rendering. These conclusions are inferred from the CWE-79 classification and vulnerability description, not confirmed via source code review. The vulnerability affects all plugin versions up to and including 3.7.

Exploitation requires an authenticated attacker with at least Contributor privileges. The attacker accesses the WordPress block editor, adds a Site Identity block to a post or page, and modifies the ‘logoTag’ attribute. The payload consists of JavaScript within the attribute value, such as . After saving the post, the malicious script persists in the database. The script executes in visitors’ browsers when they view the compromised page. The attack vector likely involves the WordPress REST API or admin-ajax.php endpoints that handle block attribute updates.

Remediation requires implementing proper input validation and output escaping. Developers should sanitize the ‘logoTag’ attribute value using functions like sanitize_text_field() before storage. They must escape the output during rendering using esc_attr() for HTML attributes. WordPress core functions like wp_kses() could also restrict allowed HTML tags. The patch should apply these security measures to all block attributes that accept user input.

Successful exploitation allows attackers to perform actions within the victim’s browser context. Attackers can steal session cookies, redirect users to malicious sites, or modify page content. Since Contributor-level users can create posts, this vulnerability enables privilege escalation if an administrator views a malicious post. The scope change (S:C) in the CVSS vector indicates the vulnerability can affect other site components beyond the plugin itself.
