Discourse is an option source discussion platform. Prior to version 2.8.14 on the `stable` branch and version 3.0.0.beta16 on the `beta` and `tests-passed` branches, pending post titles can be used for cross-site scripting attacks. Pending posts can be created by unprivileged users when a category has the "require moderator approval of all new topics" setting set. This vulnerability can lead to a full XSS on sites which have modified or disabled Discourse’s default Content Security Policy. A patch is available in versions 2.8.14 and 3.0.0.beta16.

The Swifty Page Manager plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘spm_plugin_options_page_tree_max_width’ parameter in versions up to, and including, 3.0.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.

Discourse is an option source discussion platform. Prior to version 2.8.14 on the `stable` branch and version 2.9.0.beta16 on the `beta` and `tests-passed` branches, parsing posts can be susceptible to XSS attacks. This issue is patched in versions 2.8.14 and 2.9.0.beta16. There are no known workarounds.

The JetWidgets for Elementor plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.0.12. This is due to missing nonce validation on the save() function. This makes it possible for unauthenticated attackers to to modify the plugin's settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. This can be used to enable SVG uploads that could make Cross-Site Scripting possible.

### Impact The *sanitize-svg* package uses a deny-list-pattern to sanitize SVGs to prevent cross-site scripting (XSS). In doing so, literal `<script>`-tags and on-event handlers were detected: ```typescript [...] const svgEl = div.firstElementChild! const attributes = Array.from(svgEl.attributes).map(({ name }) => name) const hasScriptAttr = !!attributes.find((attr) => attr.startsWith('on')) const scripts = svgEl.getElementsByTagName('script') return scripts.length === 0 && !hasScriptAttr ? svg : null [...] ``` There are more ways to embed JavaScript in XML files. **Anchor Tag** (requires user to click link): ```xml <svg viewBox="0 0 100 100" xmlns="http://www.w3.org/2000/svg"> <a href="javascript:alert(document.domain)"> <text x="50" y="50" text-anchor="middle">Lauritz</text> </a> </svg> ``` **Foreign Object Tag** (no user interaction required): ```xml <svg width="500" height="500" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink"> ...
