Exploitation Conditions

Exploitation requires an authenticated WordPress account with at least low-level content-editing privileges (consistent with PR:L) able to supply input to a JetElements For Elementor widget field, on a site running the plugin at version 2.9.2.6 or earlier together with Elementor. Because this is stored XSS with UI:R, the payload only triggers when another user - typically a higher-privileged administrator - subsequently views the page or admin screen containing the stored content; it does not fire automatically. The specific widget field and parameter that fail neutralization are not described in the available sources. Limiting factors: the attacker must already be authenticated, a victim must view the injected content, and the site must run the vulnerable plugin version.

Impact

This is a medium-severity stored XSS (CVSS 6.5, CWE-79) in the Crocoblock JetElements For Elementor WordPress plugin. The CVSS vector (AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L) describes a network-reachable, low-complexity flaw that nonetheless requires some authenticated privilege (PR:L) and victim interaction (UI:R), with a scope change (S:C) reflecting that injected script executes in another user's browser context. Signals are consistent but modest: there is no CISA KEV listing, so this is not confirmed actively exploited; no EPSS score was supplied, so a quantitative exploitation probability cannot be stated; and the only reference is a Patchstack database entry, not verified working exploit code, so no public exploit is identified at time of analysis. The vuln.today priority of 'this_month' aligns with a real-but-non-emergency item: the privilege and user-interaction requirements, combined with only Low impact across confidentiality, integrity and availability, make this a patch-in-routine-cycle issue rather than a drop-everything priority. The main caveat is missing data - no EPSS, no KEV, no explicit fixed version, and no independent corroboration beyond the single Patchstack reference.

Exploit ScenarioDerived

An attacker holding a low-privileged authenticated WordPress account (e.g. contributor/author able to edit Elementor content) injects a malicious script payload into a JetElements widget field that is stored without proper neutralization. When a higher-privileged user such as an administrator later views the affected page or post in wp-admin, the stored script executes in their browser session. No working public exploit code is identified; only a Patchstack database reference exists.

AnalysisAIv1 – Oct 29, 2026

Stored cross-site scripting in Crocoblock JetElements For Elementor (versions through 2.9.2.6) allows an authenticated user with low-level content-editing privileges to plant persistent script in a widget field, which then executes in the browser of any higher-privileged user who later views the affected page or admin screen. Rated CVSS 6.5 with scope change (S:C), reflecting that code runs in the victim's WordPress session context rather than the attacker's. No public exploit code was identified at time of analysis and the issue is not in CISA KEV; the required authenticated foothold plus victim interaction keeps it a medium-priority, this-month remediation item rather than an emergency.

RemediationAI

No vendor-released patch is identified in the available data at time of analysis, and no fixed version is stated, so confirm the current release and any fix on the Patchstack advisory (https://patchstack.com/database/wordpress/plugin/jet-elements/vulnerability/wordpress-jetelements-for-elementor-plugin-2-9-2-6-cross-site-scripting-xss-vulnerability?_s_id=cve) before upgrading. Until a fixed build is confirmed, reduce exposure by removing or deactivating JetElements For Elementor on sites that do not need it (the widget content and layouts using it stop rendering), and by tightening who holds content-editing roles, since the assessed exploitation path requires an authenticated account with at least low-level editing privileges - this lowers risk but does not remove it for sites with many contributor-level users. Because the payload only fires when a higher-privileged user views the injected content, review and clean existing widget field content for unexpected markup after any suspicious contributor activity, and note that neither deactivation nor role restriction addresses the underlying missing sanitization if a malicious payload is already stored.

Technical ContextAI · show details

The target is a WordPress plugin that supplies Elementor page-builder widgets; the flaw is CWE-79 (Improper Neutralization of Input During Web Page Generation), meaning user-supplied widget field content is stored and later rendered into a page without adequate sanitization or output escaping. That is the classic stored/persistent XSS pattern: the payload is persisted server-side and only detonates on a subsequent page view by another user, which is why the CVSS vector carries UI:R while still scoring S:C - the injected script executes with the privileges and origin context of the viewing user, typically an administrator in wp-admin. The CPE cpe:2.3:a:crocoblock:jetelements_for_elementor:*:*:*:*:*:*:*:* confirms the plugin as the sole affected component, with the vulnerable range extending through 2.9.2.6 and requiring Elementor to be present. The specific widget field, parameter, and rendering path that fail neutralization are not described in the available sources, so the exact injection point should be treated as unverified.
