AI Insight

LLM-synthesized narrative grounded in this CVE's description and references.

Stored XSS in Soliloquy 2.6.2 title parameter allows authenticated attackers to inject scripts that execute on admin and frontend views.

Vulnerability

Slider by Soliloquy version 2.6.2 contains a stored cross-site scripting (XSS) vulnerability in the slider title parameter [3]. Authenticated users with the ability to create or edit sliders can inject arbitrary JavaScript into the title field. The payload is stored in the database and executed when any user views the slider on both administrative and public-facing pages. The vulnerability is classified as CWE-79 [3].

Exploitation

An attacker must be an authenticated WordPress user with sufficient privileges to create or edit sliders. The attacker creates a new slider (or edits an existing one) and enters a malicious script in the title field, e.g., `` [4]. After saving and publishing the slider, the script is triggered when the slider is viewed. Accessing the slider edit page or the frontend slider display will execute the injected script [4].

Impact

Successful exploitation allows the attacker to execute arbitrary JavaScript in the context of the victim's browser. This can lead to session hijacking, credential theft, defacement, or redirection to malicious sites. The attack affects both administrators viewing the slider in the admin panel and end users browsing the live site [3][4].

Mitigation

As of the publication date, no official patch has been released for this vulnerability. Users should consider disabling the plugin or restricting slider editing capabilities to trusted users only. Monitor vendor updates for a fixed version.

Affected code

The vulnerability exists in the Slider by Soliloquy plugin version 2.6.2 for WordPress. The title parameter of slider posts is not sanitized before being stored and later rendered in the browser. The flaw affects both the administrative edit page (`wp-admin/post.php`) and the frontend slider display page.

What the fix does

No patch is included in the bundle. The advisory [ref_id=1] does not describe a vendor fix. To remediate, the plugin should properly sanitize and escape the title field output using WordPress functions such as `esc_html()` or `wp_kses_post()` to prevent JavaScript execution in the browser.

Preconditions

  • authAttacker must have an authenticated WordPress user account with permission to create or edit Soliloquy slider posts.
  • configThe Slider by Soliloquy plugin version 2.6.2 must be installed and activated.
  • networkNo special network position required; the attacker submits the payload via the WordPress admin panel over HTTP/HTTPS.

Reproduction
