CVE-2024-47326: Share This Image XSS Vulnerability

CVE-2024-47326 Overview

CVE-2024-47326 is a reflected Cross-Site Scripting (XSS) vulnerability [CWE-79] in the ILLID Share This Image plugin for WordPress. The flaw affects all plugin versions up to and including 2.01. Attackers can inject arbitrary JavaScript into web pages generated by the plugin due to improper neutralization of user-supplied input. Exploitation requires a victim to interact with a crafted link, typically delivered through phishing or social engineering. Successful exploitation executes attacker-controlled script in the victim's browser session under the affected site's origin.

Critical Impact
Attackers can hijack authenticated sessions, redirect users to malicious resources, or perform actions on behalf of victims who click crafted URLs targeting vulnerable WordPress sites.

Affected Products

ILLID Share This Image WordPress plugin (share-this-image)
All versions from initial release through 2.01
WordPress installations with the plugin active

Technical Details for CVE-2024-47326

Vulnerability Analysis

The vulnerability is a reflected XSS issue in the Share This Image plugin. The plugin echoes user-controlled request parameters back into rendered HTML without proper output encoding or input sanitization. When a victim loads a URL containing a crafted payload, the browser parses the injected markup and executes attacker-supplied JavaScript in the context of the WordPress site.

The scope is marked as changed in the CVSS vector, meaning the injected script can affect resources beyond the vulnerable component. Confidentiality, integrity, and availability are each rated low, reflecting browser-side impact rather than direct server compromise. User interaction is required, which limits mass exploitation but remains viable through phishing campaigns.

Root Cause

The root cause is improper neutralization of input during web page generation [CWE-79]. The plugin fails to apply WordPress sanitization helpers such as esc_html(), esc_attr(), or sanitize_text_field() before reflecting request data into the response. Any HTML or script syntax provided by the attacker reaches the DOM intact.

Attack Vector

The attack vector is network-based and requires no authentication. An attacker crafts a URL targeting a vulnerable endpoint of the plugin and embeds a JavaScript payload in a reflected parameter. The attacker then distributes the link through email, chat, or malicious advertising. When a victim with an active session loads the URL, the script executes in the browser, enabling cookie theft, session riding, or arbitrary DOM manipulation. Refer to the Patchstack WordPress Vulnerability Report for additional technical context.

Detection Methods for CVE-2024-47326

Indicators of Compromise

HTTP requests to Share This Image plugin endpoints containing <script>, onerror=, onload=, or encoded JavaScript payloads in query parameters
Web server access logs showing unusually long URL parameters with HTML entities or URL-encoded angle brackets
Browser console errors or unexpected outbound requests originating from pages that include the plugin

Detection Strategies

Inspect WordPress access logs for requests to share-this-image paths containing reflected parameter values with script syntax
Deploy a Web Application Firewall (WAF) rule set that flags XSS signatures targeting WordPress plugin parameters
Use Content Security Policy (CSP) violation reports to identify inline script execution attempts on pages rendered by the plugin

Monitoring Recommendations

Monitor referer headers and click telemetry for inbound traffic carrying suspicious encoded payloads to plugin endpoints
Alert on outbound browser requests from authenticated administrator sessions to unknown external domains
Track plugin version inventory across WordPress sites to identify hosts running share-this-image2.01 or earlier

How to Mitigate CVE-2024-47326

Immediate Actions Required

Identify all WordPress installations running the Share This Image plugin and confirm installed versions
Disable or remove the plugin on any site running version 2.01 or earlier until a fixed release is verified
Review administrator and editor account activity for signs of session abuse following potential exploitation

Patch Information

At the time of NVD publication, no fixed version had been listed for the Share This Image plugin. Site administrators should consult the Patchstack WordPress Vulnerability Report for the latest patch status and upgrade to any release newer than 2.01 once published by the maintainer.

Workarounds

Deactivate the Share This Image plugin until an upstream patch is released
Deploy WAF rules that block XSS payload patterns directed at plugin parameters
Enforce a strict Content Security Policy that disallows inline scripts and untrusted script sources on WordPress pages
Train administrators to avoid clicking unsolicited links pointing to their own WordPress sites with unusual query strings

bash

# Example WAF rule pattern to block reflected XSS payloads targeting the plugin
# ModSecurity-style rule
SecRule REQUEST_URI "@contains /share-this-image/" \
    "chain,deny,status:403,id:1004732601,msg:'Blocked XSS attempt against Share This Image plugin'"
    SecRule ARGS "@rx (?i)(<script|onerror=|onload=|javascript:)" "t:urlDecodeUni,t:htmlEntityDecode"
