1) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2026-97689)

CWE-ID: CWE-770 - Allocation of Resources Without Limits or Throttling

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to allocation of resources without limits or throttling in the HTTPResponse.stream() and read_chunked() methods when processing a chunked-transfer-encoded response with an unterminated chunk-size field. A remote attacker can send a crafted chunked response containing a long run of bytes without a newline to cause a denial of service.
