Does this affect you?

It affects Unknown LiteSpeed Cache. Add what you run to find out whether that includes you.

EPSS puts the chance of exploitation in the next 30 days at 0.30%, higher than 23% of scored CVEs.

The LiteSpeed Cache WordPress plugin before 7.9.2 does not restrict one of its HTML rewriting routines to stylesheet content, so it removes a quote that terminates an attribute in the rendered page, and combined with unescaped comment author output this allows unauthenticated users whose comment is published to inject attributes that execute JavaScript in the browser of any visitor, including a logged-in administrator, who views front-end pages while the affected option is enabled.
