CVE-2026-11940

A flaw was found in the `tarfile.extractall()` function within Python. A remote attacker could exploit this vulnerability by providing a specially crafted archive. This archive could bypass security filters by using a hardlink that references a symlink, allowing the symlink to be recreated outside the intended destination directory. This could lead to out-of-destination file reads or writes, potentially resulting in information disclosure or arbitrary file modification.

7.3 (High)
CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:N

CVE-2026-15308

A flaw was found in Python. Its incremental HTML parser can be exploited by a remote attacker. By sending specially crafted, uncontrolled data with repeated, incomplete markup declarations, the attacker can cause the system to consume excessive central processing unit (CPU) resources. This leads to a denial of service, making the affected system unresponsive.

7.5 (High)
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')
