Semantic MediaWiki is a free, open-source extension to MediaWiki that lets users store and query data within the wiki's pages. Prior to version 7.2.0, when `headers=plain`, table header text was emitted into `<th>` via a raw HTML path. User-controlled `mainlabel` content could therefore become executable HTML. Version 7.2.0 fixes the issue.

Affected: Packagist: mediawiki/semantic-media-wiki

#### Failure mode

When `headers=plain`, table header text was emitted into `<th>` via a raw HTML path. User-controlled `mainlabel` content could therefore become executable HTML.

#### Remediation

- `TableResultPrinter` now applies output-context escaping before passing plain headers to the table renderer. - The fix is limited to the HTML/plain-header branch so safe rendering modes are unaffected.

#### Why this is the right layer

The header value is not a structural token; it is display data. Sanitizing it at the sink is correct because the renderer owns the final HTML emission.
