When an attacker sends a specially crafted HTTP GET request containing excessively long values for the name, en, user_id, shibie_name, time, act, log, or rpri parameters, the server overwrites memory on the stack.

The EPSS score is less than 1\u202f%, suggesting that current exploitation efforts are very low, and the vulnerability is not yet catalogued in the CISA KEV list. Attackers could reach the vulnerable endpoint remotely over HTTP, so the attack vector is likely external. The likelihood of accidental exploitation is low, but the potential compromise is severe, so the overall risk remains high until the firmware is updated."}}}}, "created": "2026-04-08T19:36:24.822934+00:00", "title": "Buffer Overflow in D\u2011Link DI\u20118003 /xwgl_ref.asp Endpoint", "updated": "2026-04-14T16:40:42.147760+00:00", "vendors": ["dlink", "dlink$PRODUCT$di-8003"]}
