Exploitation Conditions

Exploitation requires an existing authenticated WordPress account with at least low-level privileges (PR:L) capable of submitting content through an Element Pack Elementor widget or input field in versions up to and including 8.8.6, where input is improperly neutralized before web-page generation. Execution additionally requires user interaction (UI:R): a victim - typically an administrator or other user - must view the page containing the stored payload for the script to fire. Limiting factors: the attacker cannot be fully anonymous (no PR:N), the plugin must be installed and the vulnerable widget/feature in use, and successful compromise depends on a higher-privileged user rendering the injected content.

Impact

This is a moderate-priority issue, not a top-tier emergency. The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L, base 6.5) indicates a network-reachable but privilege-and-interaction-gated flaw: an attacker needs an existing authenticated low-privilege WordPress account (PR:L) and a victim must view the malicious content (UI:R). The scope change (S:C) and partial C/I/A impacts reflect typical stored-XSS behavior where injected script executes in a victim's browser session, potentially under a higher-privileged admin context. No EPSS score, CISA KEV listing, or public POC was provided in the input, so there is no signal of active exploitation - status is 'no public exploit identified at time of analysis.' Signals are internally consistent (no CVSS-vs-description conflict), but exploitation probability data (EPSS) is entirely missing, limiting quantitative risk ranking. Stored XSS in a popular Elementor addon is realistically exploitable in multi-author WordPress environments but is gated by the requirement for a pre-existing contributor/author account and admin interaction, keeping real-world risk moderate rather than critical.

Exploit ScenarioDerived

An authenticated low-privilege user (e.g., contributor or author) on a WordPress site running Element Pack injects a malicious script payload through a vulnerable plugin input/widget that is stored and later rendered. When an administrator or other user views the affected page or post, the script executes in their browser, enabling session hijacking or actions in the admin context. No public exploit code was identified in the provided data.

AnalysisAIv1 – Oct 07, 2026

Stored cross-site scripting (XSS) in Element Pack Elementor Addons through version 8.8.6 allows authenticated users with low-level privileges to inject malicious scripts into pages via vulnerable widgets or input fields. The injected payload executes when a higher-privileged user views the compromised page, potentially leading to session hijacking or site takeover. No public exploit identified at time of analysis, and no vendor-released patch is specified in the provided data.

RemediationAI

No vendor-released patch is identified in the provided data. Administrators should monitor the Patchstack advisory for an updated version and apply it promptly once available. As a workaround, consider disabling the Element Pack Elementor Addons plugin until a fix is released, or restrict the ability of low-privilege users to submit content through Element Pack widgets by adjusting WordPress role capabilities (e.g., remove unfiltered_html for contributors). Additionally, a web application firewall (WAF) with XSS filtering rules can help block exploitation attempts, though it may not fully mitigate stored XSS. Note that disabling the plugin may break site functionality that relies on its widgets.

Technical ContextAI · show details

The vulnerability is a classic CWE-79: Improper Neutralization of Input During Web Page Generation, specifically a stored XSS in the WordPress plugin Element Pack Elementor Addons (bdthemes-element-pack-lite). The plugin extends Elementor with widgets and features, and input submitted through certain widgets or fields is not properly sanitized or escaped before being rendered on a web page. This allows an attacker with a low-privilege authenticated account (e.g., contributor) to store malicious JavaScript that executes in the context of any user visiting the affected page. The CVSS vector (AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L) indicates network exploitation, low attack complexity, low privileges required, and user interaction needed; scope is changed because the script can affect resources beyond the vulnerable component. Affected CPE: cpe:2.3:a:bdthemes:element_pack_elementor_addons:*:*:*:*:*:*:*:* covering versions up to 8.8.6.
