Repeated header names cause previously allocated header strings to be leaked, and HPACK compression allows an unauthenticated remote attacker to trigger tens of thousands of duplicate headers with a small request. Repeated crafted requests can cause persistent heap growth, exhaust process memory, and terminate the affected Open5GS network function, resulting in denial of service."}],"affected":[{"vendor":"n/a","product":"n/a","versions":[{"version":"n/a","status":"affected"}]}],"references":[{"url":"https://github.com/open5gs/open5gs/issues/4788"},{"url":"https://github.com/open5gs/open5gs/commit/76f15375ead1b2db09193458e56640da0a86c255"},{"url":"https://gist.github.com/hackeryounow/c923fad9de83011004bd7d078b817dc0"}],"problemTypes":[{"descriptions":[{"type":"text","lang":"en","description":"n/a"}]}]},"adp":[{"problemTypes":[{"descriptions":[{"type":"CWE","cweId":"CWE-400","lang":"en","description":"CWE-400 Uncontrolled Resource Consumption"}]}],"references":[{"url":"https://github.com/open5gs/open5gs/issues/4788","tags":["exploit"]}],"metrics":[{"cvssV3_1":{"scope":"UNCHANGED","version":"3.1","baseScore":7.5,"attackVector":"NETWORK","baseSeverity":"HIGH","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","integrityImpact":"NONE","userInteraction":"NONE","attackComplexity":"LOW","availabilityImpact":"HIGH","privilegesRequired":"NONE","confidentialityImpact":"NONE"}},{"other":{"type":"ssvc","content":{"timestamp":"2026-11-05T16:33:27.295265Z","id":"CVE-2026-106806","options":[{"Exploitation":"poc"},{"Automatable":"yes"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-11-05T16:34:18.009Z"}}]},"dataVersion":"5.2"}
