CVE-2026-116881 · Semantic MediaWiki 3.0.0 before 7.3.1 XSS via Property-Value Autocomplete
This page contains facts from public vulnerability sources. Check the original advisory before updating.
Semantic MediaWiki from 3.0.0 before 7.3.1 contains a cross-site scripting vulnerability that allows attackers to inject markup by storing malicious semantic property values rendered unescaped in autocomplete suggestions. When another user opens the property-value autocomplete with an empty query, jquery.autocomplete.js concatenates the raw PValueLookup API value into HTML via container.html(), altering the dropdown and potentially executing script.
