Stored XSS in ShareOpenly WordPress Plugin

Publication date: 2026-08-07

Last updated on: 2026-08-07

Assigner: GitHub, Inc.

Description
The ShareOpenly WordPress plugin prior to version 1.2.1 contains a Cross-Site Scripting vulnerability caused by the absence of WordPress's `esc_url()` escaping function on the `$url` variable before it is rendered into HTML content. This variable is constructed from `home_url( add_query_arg( array(), $wp->request ) )` and is concatenated directly into an HTML `href` attribute on every singular post or page where the plugin's sharing link is displayed. WordPress's security handbook mandates that every URL placed in HTML output must be passed through `esc_url()`, which both HTML-encodes special characters (converting `"`, `<`, `>` into their safe HTML entity equivalents) and strips dangerous URI schemes such as `javascript:` and `data:`. The omission of this function means that if the `$url` value ever contains HTML-special characters or a dangerous URI scheme — through a `home_url` WordPress filter applied by another plugin or theme, through certain web server or hosting configurations, or through future code changes — the unescaped content will be injected verbatim into the rendered HTML of every post or page on the site. Version 1.2.1 contains a patch for the issue.

Executive Summary

The ShareOpenly WordPress plugin before version 1.2.1 has a Cross-Site Scripting (XSS) vulnerability. It fails to escape the $url variable using WordPress's esc_url() function before rendering it in HTML. This allows untrusted input to be injected into web pages, potentially executing malicious scripts in users' browsers.

Detection Guidance

To detect this vulnerability, check if the ShareOpenly WordPress plugin version is below 1.2.1. Use commands like 'wp plugin list' in WordPress CLI or inspect the plugin version in the WordPress admin panel. Review the file inc/add-sharing-link.php for missing esc_url() usage on the $url variable.

Impact Analysis

An attacker could exploit this to inject malicious scripts into your website. This may lead to session hijacking, stealing user credentials, defacing your site, or distributing malware to visitors. All site visitors could be affected if the vulnerability is exploited.

Compliance Impact

This vulnerability could lead to data breaches, compromising user data and violating privacy regulations like GDPR and HIPAA. Non-compliance may result in legal penalties, reputational damage, and loss of trust.

Mitigation Strategies

Immediately update the ShareOpenly plugin to version 1.2.1 or later. If updating is not possible, manually patch the code by adding esc_url() to the $url variable in inc/add-sharing-link.php line 36 and replace esc_html() with esc_attr() in inc/settings.php lines 149 and 162.
