Attack profile from CVSS 3.1 · CNA. Fix status from CNA, GitHub and Red Hat. Impact type from CWE-407.
Summary
ASP.NET Core 8.0 from 8.0 before 8.0.32, 9.0 from 9.0 before 9.0.21 and 10.0 from 10.0 before 10.0.13 are affected. Inefficient algorithmic complexity (CWE-407) lets an unauthorized attacker over the network deny service. The attack is rated high complexity and needs no user interaction. The facts report no known exploitation.
