Prior to 4.1.0, with the default $wgEmbedVideoRequireConsent configuration enabled, includes/EmbedService/EmbedHtmlFormatter.php places JSON returned through includes/EmbedService/AbstractEmbedService.php into the data-mw-iframeconfig attribute without safely escaping single quotes. Attacker-controlled archiveorg identifiers and wistia or sharepoint URLs accepted by the affected service validators can cause getUrl() output to terminate the attribute and inject event-handler attributes into the generated figure element. A user able to edit a wiki page can store JavaScript that executes in the wiki origin when visitors render the page. This issue is fixed in version 4.1.0.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Package advisory (CVE-2026-55692)\n\nAffected packages:\n\n- `starcitizenwiki/embedvideo <= 4.0.0`\n\nPatched in:\n\n- `starcitizenwiki/embedvideo 4.1.0`\n\nSource: https://github.com/advisories/GHSA-5c7p-g73q-rpg5","depth":"midnight","depthScore":53,"depthScoreParts":{"impact":41.3,"likelihood":0.1,"exploitation":12,"ransomware":0},"changes":[{"seq":204484,"id":"CVE-2026-55692","ts":1789501414836,"field":"exploit_available","old":"false","new":"true"}]}
