Semantic MediaWiki has reflected XSS in `Special:SearchByProperty` (`property` and `value` parameters)
The advisory, in context
Failure mode
The value parameter was reflected back into rendered output and error messaging paths without enough output-context encoding.
Remediation
- The form value is escaped before it is placed back into the input field.
- Derived error messages are also escaped before being rendered into HTML.
Maintenance note
Do not treat error text as trusted just because it originated from validation. Validation output can still be attacker-influenced.
Affected packages
Start with the recorded fix for your release branch. Check your installed version and test compatibility before upgrading. Fixing this advisory does not rule out other vulnerabilities in the release.
