CVE-2026-110703 in GeoDirectory Plugin
Summary
by MITRE • 10/16/2026
The GeoDirectory – WP Business Directory Plugin and Classified Listings Directory plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'post_content' parameter in all versions up to, and including, 2.8.191 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This requires the attacker to own a published listing, as the ownership check in GeoDir_Post_Data::can_edit() limits who can store the payload; however, because ajax_save_post() re-applies the existing post_status, edits to an already-published listing bypass re-moderation and remain live immediately.
Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
Analysis

The vulnerability identified within the GeoDirectory plugin for WordPress represents a significant security risk stemming from insufficient input sanitization and output escaping mechanisms in the handling of user-supplied data. Specifically, this flaw affects all versions up to and including 2.8.191 through the post_content parameter associated with business directory listings and classified ads. The core technical deficiency lies in the application's failure to properly validate or encode content before storing it in the database and subsequently rendering it on public-facing pages. This lack of rigorous data handling allows malicious actors to inject arbitrary web scripts into the system, which are then executed by any user who views the compromised listing page.
The operational impact of this vulnerability is characterized as a Stored Cross-Site Scripting attack, commonly referred to in industry standards such as CWE-80 and mapped within the MITRE ATT&CK framework under techniques involving client-side code injection. Unlike reflected XSS where payload delivery requires complex social engineering or link manipulation for each victim, stored XSS persists on the server side. This means that once a malicious script is injected into a listing's content field, it remains active until manually removed by an administrator. Consequently, every user who accesses the affected page becomes a potential target for session hijacking, credential theft, defacement, or redirection to phishing sites without any additional interaction required from the attacker beyond the initial injection.
Access control mechanisms within GeoDirectory present a nuanced attack vector that requires careful exploitation. The vulnerability is not open to unauthenticated users due to an ownership check implemented in the GeoDir_Post_Data::can_edit() function, which restricts who can modify listing data based on user roles and post ownership. Therefore, attackers must possess at least subscriber-level access and own a published listing to leverage this flaw. However, the security model contains a critical logic error regarding moderation workflows. The ajax_save_post() function is designed to re-apply the existing post_status during an edit operation rather than resetting it to pending for review. This design choice allows authenticated attackers with ownership of a live listing to bypass content moderation processes entirely. By editing their own published listings, they can inject malicious payloads that go live immediately without triggering any secondary approval steps or administrative oversight.
Mitigation strategies must address both the immediate technical flaw and broader security hygiene practices within WordPress environments. The primary remediation is to upgrade the GeoDirectory plugin to a version released after 2.8.191 where these sanitization and escaping issues have been corrected by the developers. For organizations unable to patch immediately, implementing strict Content Security Policy headers can help mitigate the impact of script execution in browsers that support them. Additionally, administrators should enforce rigorous input validation on all user-facing forms and ensure that output encoding is applied consistently across all template files rendering listing content. Regular audits of plugin code for proper use of WordPress sanitization functions such as wp_kses_post or esc_html are essential to prevent similar vulnerabilities from being introduced in future updates or custom modifications.
