BIT-MONGODB-2026-13074 Awaitable Hello Command in Exhaust Mode Unthrottled Response Loop Leading to Denial of Service

An unauthenticated remote client can cause excessive CPU consumption on a MongoDB server by sending a specific combination of parameters to the awaitable hello command in exhaust mode. The server's handling of this combination results in a response loop that bypasses normal throttling, allowing a...

CVE-2026-66046

Expat through 2.8.3 contains a denial of service vulnerability caused by quadratic algorithmic complexity in the storeAtts function in xmlparse.c, where processing N specified attributes with non-normalized values triggers an ON^2 linear scan of elementType-defaultAtts to determine CDATA status. ...

mime: golang: Golang MIME: Denial of Service via maliciously-crafted MIME header

A flaw was found in the Golang MIME Multipurpose Internet Mail Extensions package. A remote attacker could exploit this vulnerability by sending a maliciously-crafted MIME header containing many invalid encoded-words. This could lead to excessive CPU consumption, resulting in a Denial of Service...

Denial of Service (DoS)

Overview Affected versions of this package are vulnerable to Denial of Service DoS via the groupcomments function in sqlparse/engine/grouping.py when parsing a statement composed entirely of comment tokens e.g., repeated -- c\n lines. The function rescans the entire remaining token tail once per...
