EchelonGraph scoreLOW confidence

This high-severity CVE scores 7.5 under the CNA's CVSS (NVD's own analysis pending). EPSS exploit-prediction score not yet available (the EPSS model rescores nightly; freshly-published CVEs typically appear within 48 hours). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

StarCitizenWiki Extension Embed Video: Stored XSS via malformed src url with $wgEmbedVideoRequireConsent enabled

Summary

With $wgEmbedVideoRequireConsent enabled (the default), the urls for videos are stored in a json-ified data attributedata-mw-iframeconfig. When given a malformed url or id, the data-mw-iframeconfig attribute can be escaped via single quotes, allowing for html/javascript injection.

Details

The sprintf here adds the iframe config encoded as JSON here. When given a malicious url or id with a single quote, the $this->getUrl() call returns an unescaped payload that terminates the data-mw-iframeconfig attribute and allows for injecting attributes, including handlers, into the figure element. The id regex for the archiveorg service and the url regexes for the wistia and sharepoint services allow for single quotes to be introduced.

PoC

{{#ev:sharepoint|https://a.sharepoint.com/sites/x'onmouseover='alert(document.domain)'.aspx}}

Impact

Under the default $wgEmbedVideoRequireConsent = true configuration, any user able to edit a page can inject arbitrary JavaScript into an HTML event handler attribute (e.g. onfocus) via parameter. It requires no interaction (autofires via autofocus) and executes in the wiki origin for every visitor to the page.
