AnalysisAI
Oracle Communications Cloud Native Core Security Edge Protection Proxy (SEPP) versions 26.1.200 and 25.2.201 are exposed to an unauthenticated, low-complexity attack launched from the adjacent network segment on which the SEPP host resides. A successful exploit gives the attacker high-impact read access to critical SEPP data plus limited ability to modify or delete that data (CVSS 3.1 base 7.1, AV:A/AC:L/PR:N/UI:N/C:H/I:L/A:N), which in a 5G roaming architecture could mean exposure of inter-PLMN signaling and subscriber-adjacent metadata. …
