CVE-2025-55904
Open5GS v2.7.5, prior to commit 67ba7f92bbd7a378954895d96d9d7b05d5b64615, is vulnerable to a NULL pointer dereference when a multipart/related HTTP POST request with an empty HTTP body is sent to the SBI of either AMF, AUSF, BSF, NRF, NSSF, PCF, SMF,…
Does this matter?
Lower severity and a low EPSS score (0.21%). Track it; it rarely justifies an emergency change on its own.
