Summary

wlc: print_html outputs API data without HTML escaping

Details

Impact

The HTML output format in wlc embeds API response data into HTML without escaping, allowing cross-site scripting when the output is rendered in a browser.

Patches

https://github.com/WeblateOrg/wlc/pull/1327

Workarounds

The only vulnerable code path is HTML output which is opt-in.
