This high-severity CVE scores 8.8 under NVD CVSS v3. EPSS exploit probability: 2.7%, top 16% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

An issue was discovered on Wavlink Jetstream devices where a crafted POST request can be sent to adm.cgi that will result in the execution of the supplied command if there is an active session at the same time. The POST request itself is not validated to ensure it came from the active session. Affected devices are: Wavlink WN530HG4, Wavlink WN575A3, Wavlink WN579G3,Wavlink WN531G3, Wavlink WN533A8, Wavlink WN531A6, Wavlink WN551K1, Wavlink WN535G3, Wavlink WN530H4, Wavlink WN57X93, WN572HG3, Wavlink WN578A2, Wavlink WN579G3, Wavlink WN579X3, and Jetstream AC3000/ERAC3000
