tt-rss project reports:

The cached_url feature mishandles JavaScript inside an SVG document.
imgproxy in plugins/af_proxy_http/init.php mishandles $_REQUEST[“url”] in an error message.
It does not validate all URLs before requesting them.

Allows remote attackers to execute arbitrary PHP code via a crafted plural forms header.
