Sherk Custom Post Type Displays <= 1.2.1 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'title' Shortcode Attribute

The Sherk Custom Post Type Displays plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'title' shortcode attribute in all versions up to, and including, 1.2.1. This is due to insufficient input sanitization and output escaping on the 'title' attribute of the 'sherkcptdisplays' shortcode. Specifically, in the sherkcptdisplays_func() function in includes/SherkCPTDisplaysShortcode.php, the 'title' attribute value is extracted from shortcode_atts() on line 19 and directly concatenated into an HTML <h2> tag on line 31 without any escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The Wikilookup plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'Popup Width' setting in all versions up to, and including, 1.1.5. This is due to insufficient input sanitization and output escaping.

Sheets2Table <= 0.4.1 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'titles' Shortcode Attribute

The Sheets2Table plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'titles' shortcode attribute in the [sheets2table-render-table] shortcode in all versions up to and including 0.4.1. This is due to insufficient input sanitization and output escaping. Specifically, the 'titles' attribute value from the shortcode is passed through S2T_Functions::trim_array_values() (which only trims whitespace) and then echoed directly into HTML via `echo $header` inside a <th> tag in the display_table_header() function without any escaping such as esc_html(). This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Paypal Shortcodes <= 0.3 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'amount' and 'name' Shortcode Attributes

The Paypal Shortcode plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'amount' and 'name' shortcode attributes in all versions up to, and including, 0.3. This is due to insufficient input sanitization and output escaping on user-supplied shortcode attributes. The swer_paypal_shortcode() function extracts shortcode attributes using extract() and shortcode_atts() at line 89, then directly concatenates the $name and $amount values into HTML input element value attributes at lines 105-106 without applying esc_attr() or any other escaping function. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The WordPress PayPal Donation plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'donate' shortcode in all versions up to, and including, 1.01. This is due to insufficient input sanitization and output escaping on user-supplied shortcode attributes such as 'amount', 'email', 'title', 'return_url', 'cancel_url', 'ccode', and 'image'. The wordpress_paypal_donation_create() function uses extract(shortcode_atts(...)) to process shortcode attributes and then directly interpolates these values into HTML output within single-quoted attribute values without any escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The Alfie – Feed Plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'naam' parameter in all versions up to, and including, 1.2.1. This is due to missing nonce validation on the alfie_option_page() function combined with insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject malicious web scripts that will be stored in the plugin's database and execute whenever a user accesses the page displaying the injected data, granted they can trick a site administrator into performing an action such as clicking on a link.

The fyyd podcast shortcodes plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'fyyd-podcast', 'fyyd-episode', and 'fyyd' shortcodes in all versions up to, and including, 0.3.1. This is due to insufficient input sanitization and output escaping on user-supplied shortcode attributes such as 'color', 'podcast_id', and 'podcast_slug'. These attributes are directly concatenated into inline JavaScript within single-quoted string arguments without any escaping or sanitization, allowing an attacker to break out of the JavaScript string context.

Text Toggle <= 1.1 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'title' Shortcode Attribute

The Text Toggle plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'title' shortcode attribute of the [tt_part] and [tt] shortcodes in all versions up to and including 1.1. This is due to insufficient input sanitization and output escaping on user-supplied shortcode attributes. Specifically, in the avp_texttoggle_part_shortcode() function, the 'title' attribute is extracted from shortcode attributes and concatenated directly into HTML output without any escaping — both within an HTML attribute context (title="...") on line 116 and in HTML content on line 119. While the 'class' attribute is properly validated using ctype_alnum(), the 'title' attribute has no sanitization whatsoever. An attacker can inject double-quote characters to break out of the title attribute and inject arbitrary HTML attributes including event handlers. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The Multi Functional Flexi Lightbox plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the `arv_lb[message]` parameter in all versions up to, and including, 1.2 due to insufficient input sanitization and output escaping. This is due to the `arv_lb_options_val()` sanitize callback returning user input without any sanitization, and the stored `message` value being output in the `genLB()` function without escaping. This makes it possible for authenticated attackers, with Administrator-level access, to inject arbitrary web scripts in pages that will execute whenever a user accesses a page or post with the lightbox enabled.

This is due to insufficient input sanitization and output escaping on user-supplied shortcode attributes such as 'width', 'height', 'src', 'title', 'description', 'game_url', 'main', and 'thumb', which are all directly concatenated into HTML output without any escaping.

Papra has an HTML Injection in Transactional Emails via Unescaped User Display Name

Papra is a minimalistic document management and archiving platform. Prior to 26.4.0, transactional email templates in Papra interpolate user.name directly into HTML without escaping or sanitization. An attacker who registers with a display name containing HTML tags will have those tags injected into the verification and password reset email bodies. Since emails are sent from the legitimate domain (e.g: auth@mail.papra.app), this enables convincing phishing attacks that appear to originate from official Papra notifications. This vulnerability is fixed in 26.4.0.

WWBN AVideo Vulnerable to stored XSS via Unanchored Duration Regex in Video Encoder Receiver

WWBN AVideo is an open source video platform. In versions 29.0 and below, the `isValidDuration()` regex at `objects/video.php:918` uses `/^[0-9]{1,2}:[0-9]{1,2}:[0-9]{1,2}/` without a `$` end anchor, allowing arbitrary HTML/JavaScript to be appended after a valid duration prefix. The crafted duration is stored in the database and rendered without HTML escaping via `echo Video::getCleanDuration()` on trending pages, playlist pages, and video gallery thumbnails, resulting in stored cross-site scripting. Commit bcba324644df8b4ed1f891462455f1cd26822a45 contains a fix.
