Before a certain code update, an attacker could send specially crafted network messages that trick the server into allocating huge amounts of memory using very few packets, potentially causing a denial of service (making the service unavailable by exhausting its resources).","solution":"This issue has been fixed by commit 8b178e6.","labels":["security"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-44433","publishedAt":"2026-07-16T23:16:16.727Z","cveId":"CVE-2026-44433","cweIds":["CWE-400","CWE-770"],"cvssScore":"5.3","cvssSeverity":"medium","severity":"medium","attackType":["denial_of_service"],"issueType":"vulnerability","affectedPackages":null,"affectedVendors":[],"affectedVendorsRaw":["H2O HTTP server"],"classifierModel":"claude-haiku-4-5-20251001","classifierPromptVersion":"v3","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","attackVector":"network","attackComplexity":"low","privilegesRequired":"none","userInteraction":"none","exploitMaturity":"unknown","epssScore":0,"patchAvailable":null,"disclosureDate":"2026-07-16T23:16:16.727Z","capecIds":["CAPEC-125","CAPEC-130"],"crossRefCount":0,"attackSophistication":"moderate","impactType":["availability"],"aiComponentTargeted":null,"llmSpecific":false,"classifierConfidence":0.65,"researchCategory":null,"atlasIds":null}}
