Stored cross-site scripting in LiteSpeed Cache for WordPress (versions up to and including 5.7) allows remote unauthenticated attackers to inject persistent malicious scripts that execute in the context of any user - including administrators - visiting affected pages. Publicly available exploit code exists and EPSS scores this at 82.03% (99th percentile), indicating very high probability of opportunistic exploitation across the millions of WordPress sites running this plugin. No CISA KEV listing at time of analysis, but the combination of high EPSS, public POC, and massive install base makes this a priority for WordPress operators.
