Unauthenticated SSRF in the Gutenverse Companion WordPress plugin (all versions through 2.5.1) allows remote unauthenticated attackers to induce the server to issue arbitrary HTTP requests to internal or external targets. The vulnerability carries a changed scope (S:C) in its CVSS vector, indicating potential for pivoting from the WordPress application layer to backend infrastructure. No public exploit code or CISA KEV listing has been identified at time of analysis, but the zero-authentication barrier makes this broadly exploitable against any unpatched WordPress installation running this plugin.
Stored Cross-Site Scripting in the Gutenverse FSE blocks plugin for WordPress (all versions through 4.0.2) enables authenticated attackers holding Contributor-level accounts or higher to embed persistent malicious JavaScript into page content via multiple vulnerable block types. Because the injected payload executes automatically in any visitor's browser session, the attack surface extends beyond the contributing user to all site visitors and administrators who load the affected pages. Exploitation requires no public exploit kit - the attack is straightforward for any party who can author content on the target WordPress site, and the CVSS scope change (S:C) reflects the cross-context browser impact.
Stored Cross-Site Scripting in the Gutenverse - WordPress Blocks, Page Builder & Site Editor plugin (all versions through 4.0.2) permits authenticated contributors to persist arbitrary JavaScript via the titleTag block attribute. The vulnerability is architecturally subtle: the malicious payload bypasses WordPress's wp_kses_post sanitization at save time by residing inside a Gutenberg block-comment delimiter, and the dangerous HTML is only synthesized when do_blocks() renders the page, at which point no further escaping is applied. Because the injected script fires in administrator and editor browser sessions during post preview, a contributor can effectively escalate impact to admin-level session hijacking. No public exploit identified at time of analysis.
Stored Cross-Site Scripting in the Gutenverse WordPress Blocks, Page Builder & Site Editor plugin (all versions through 3.8.0) enables authenticated editor-level users to persist arbitrary JavaScript into pages served to any site visitor. The vulnerability is constrained to WordPress multi-site installations or single-site deployments where unfiltered_html has been explicitly disabled. No public exploit has been identified at time of analysis, and a upstream fix commit (changeset 3578328) has been published to the WordPress plugin repository.
Missing Authorization vulnerability in Jegstudio Startupzy startupzy allows Exploiting Incorrectly Configured Access Control Security Levels.1.1. Rated medium severity (CVSS 4.3), this vulnerability is remotely exploitable, low attack complexity. No vendor patch available.
Server-Side Request Forgery in Gutenverse - Ultimate WordPress FSE Blocks Addons & Ecosystem plugin versions up to 3.5.3 allows authenticated contributors and above to initiate arbitrary web requests from the vulnerable server via the import_images() function, enabling query and modification of internal services. The vulnerability is exploitable without user interaction over the network, affecting sites with contributor-level users or higher.
Stored Cross-Site Scripting in Gutenverse - Ultimate WordPress FSE Blocks Addons & Ecosystem plugin up to version 3.5.3 allows authenticated attackers with contributor-level access to inject arbitrary JavaScript into pages via the 'separatorIconSVG' parameter, executing malicious scripts whenever users view affected pages. The vulnerability stems from insufficient input sanitization and output escaping. No public exploit code or active exploitation has been identified at the time of analysis.
Stored Cross-Site Scripting in Gutenverse - Ultimate WordPress FSE Blocks Addons & Ecosystem plugin versions up to 3.4.6 allows authenticated attackers with contributor-level access or higher to inject arbitrary JavaScript via the 'imageLoad' parameter, resulting in persistent script execution in pages viewed by other users. CVSS 6.4 reflects medium severity with cross-site scope; no public exploit code or active exploitation has been identified at the time of analysis, but the vulnerability requires only low privileges and no user interaction beyond initial page access.
The Gutenverse News plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘elementId’ parameter in all versions up to, and including, 1.0.4 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
The Gutenverse - Ultimate Block Addons and Page Builder for Site Editor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's countdown Block in all versions up to, and. Rated medium severity (CVSS 6.4), this vulnerability is remotely exploitable, low attack complexity. This Cross-Site Scripting (XSS) vulnerability could allow attackers to inject malicious scripts into web pages viewed by other users.
Improper Neutralization of Input During Web Page Generation (XSS or 'Cross-site Scripting') vulnerability in Jegstudio Gutenverse allows Stored XSS.9.4. Rated medium severity (CVSS 5.4), this vulnerability is remotely exploitable, low attack complexity. No vendor patch available.
Improper Neutralization of Input During Web Page Generation (XSS or 'Cross-site Scripting') vulnerability in Jegstudio Gutenverse allows Stored XSS.9.2. Rated medium severity (CVSS 5.4), this vulnerability is remotely exploitable, low attack complexity. No vendor patch available.
The Gutenverse WordPress plugin before 1.9.1 does not validate the htmlTag option in various of its block before outputting it back in a page/post where the block is embed, which could allow users. Rated medium severity (CVSS 6.1), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
