Directory traversal in the Nexter Blocks WordPress plugin (all versions through 5.0.0) allows authenticated attackers holding only subscriber-level accounts to delete arbitrary JavaScript and CSS files on the server by manipulating the unsanitized 'plus_name' parameter. Successful exploitation can destroy plugin and theme asset files, causing denial of service or permanent visual breakage of affected WordPress sites. No public exploit has been identified at time of analysis, and this vulnerability is not listed in the CISA KEV catalog; however, the low authentication bar (subscriber-level) meaningfully elevates real-world risk for multi-tenant or open-registration WordPress deployments.
Stored cross-site scripting in the Nexter Blocks - Gutenberg Blocks, Page Builder & AI Website Builder WordPress plugin (versions through 4.7.4) enables authenticated contributors to persistently inject malicious JavaScript via the unsanitized 'commentIcon' parameter, executing in any visitor's browser on affected pages. The CVSS Scope:Changed metric reflects that attacker-controlled code crosses trust boundaries into the victim's browser session, enabling session hijacking, credential theft, or unauthorized actions on behalf of privileged users such as site administrators. No public exploit code or CISA KEV listing was identified at time of analysis.
