Summary

The ShareOpenly WordPress plugin prior to version 1.2.1 contains a Cross-Site Scripting vulnerability due to the absence of WordPress's esc_url() escaping function on the $url variable before it is rendered into HTML. This variable is constructed from home_url() and concatenated into an href attribute on every singular post or page.

Risk Assessment

An attacker could inject malicious scripts into pages, potentially leading to user session theft or other XSS attacks.

Recommendation

Update the ShareOpenly plugin to version 1.2.1 or later. Check if other plugins modify home_url in an unsafe way.

Original NVD description (English source)

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.
