The flaw permits a client to send an unlimited number of trailer headers, so unbounded memory allocations can occur. This results in memory exhaustion that can lead to crashes or denial of service for legitimate traffic. The weakness maps to CWE\u2011400 and CWE\u2011770.", "risk_and_exploitability": "The CVSS score of 6.9 indicates moderate severity, and the EPSS score of less than 1% suggests low current exploit activity. The vulnerability is not listed in CISA's KEV catalog.

If exploited, memory consumption can grow without bound, potentially exhausting system resources and causing service interruption."}}}}, "created": "2026-04-02T07:47:52.165883+00:00", "updated": "2026-04-07T08:07:30.620950+00:00", "vendors": ["aio-libs", "aio-libs$PRODUCT$aiohttp"]}
