CVE Summary Severity CVSS EPSS Priority Signals
CVE-2026-74843 Remote code execution in Wavlink WN531P3 and WN535M1 (firmware V250922) consumer routers arises from an unsafe strcpy in the export_pingortrace.cgi binary, where the attacker-controlled HTTP_COOKIE header is copied into a fixed stack buffer without bounds checking. Unauthenticated remote attackers can send a crafted Cookie header to the device web interface to overflow the stack and hijack execution. Publicly available exploit code exists (disclosed via VulDB with a PoC report), but there is no public exploit identified as actively exploited in the wild, and no CISA KEV listing.
