Attack profile from CVSS 3.1 · CISA ADP. Fix status from CNA and Red Hat. Impact type from CWE-770.
Summary
The Go standard library net/http package is affected in versions before 1.26.9 and from 1.27.0-0 before 1.27.2. The parser for Range headers sets no limit on their size (CWE-770), so a header with a large number of small ranges makes FileServer, ServeContent and ServeFile consume excessive CPU. A remote attacker without privileges or user interaction can trigger this over the network.

Description from the CNA
When parsing a Range header containing a large number of small ranges, FileServer(FS), ServeContent, and ServeFile(FS) can consume an excessive amount of CPU.
