Open5GS 1.3.0 through 2.8.0 contains a heap out-of-bounds write vulnerability in parse_multipart() that allows unauthenticated attackers to corrupt memory by supplying an empty multipart boundary. Attackers can send a single crafted multipart/related request to the SBI interface of any network function, overflowing the lookbehind buffer and crashing it.
