CVE-2025-11678 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. Stack-based Buffer Overflow in lws_adns_parse_label in warmcat libwebsockets allows, when the LWS_WITH_SYS_ASYNC_DNS flag is enabled during compilation, to overflow the label_stack, when the attacker is able to sniff a DNS request in order to craft a response with a matching id containing a label longer than the maximum.. EPSS estimates a 0.27% chance of exploitation in the next 30 days.
