CVE-2026-23490

A flaw was found in pyasn1, a generic ASN.1 library for Python. A remote attacker could exploit this vulnerability by sending a specially crafted RELATIVE-OID with excessive continuation octets. This input validation vulnerability leads to memory exhaustion, resulting in a Denial of Service (DoS) for the affected system.

CVE-2026-44432

A flaw was found in urllib3, an HTTP client library for Python. This vulnerability allows a remote attacker to cause excessive resource consumption, such as high CPU usage and massive memory allocation, on the client side. This occurs when urllib3 attempts to decompress an entire HTTP response, even if only a partial read was requested, or when draining the connection after a partial decompression. This can lead to a Denial of Service (DoS) condition.

7.5 (High)
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
CWE-409 - Improper Handling of Highly Compressed Data (Data Amplification)
