Under specific conditions, a remote user with prior legitimate access could retain access to protected system resources beyond the intended authorization period. Successful exploitation could result in continued unauthorized access.","summary":"HPE (the CNA) lists Private 5G Core up to and including 1.26.1.4 as affected. A user who once had legitimate access may keep reaching protected resources after their account or session state changes. HPE's bulletin HPESBNW05179 is referenced by NVD, but I could not read it, so the fixed version is unknown. Anyone running Private 5G Core 1.26.1.4 or earlier should look at it; teams without it can skip it.","severity":"high","cvss":8.1,"epss":null,"exploited":false,"exploited_at":null,"products":[{"name":"Private 5G Core","fixed":[],"affected":"<= 1.26.1.4","ecosystem":"vendor"}],"ecosystems":[],"tags":["authentication","hpe","other","private-5g-core","session-management"],"not_affected_if":[],"how_to_check":"Check the installed Private 5G Core version. 1.26.1.4 or earlier is in the affected range.
