CVE-2026-49852
Summary: CVE-2026-49852 affects the Python library joserfc. Prior to version 1.6.8, joserfc.jwt.decode can accept attacker-forged HS256/HS384/HS512 tokens if the verification key is empty or None, enabling potential authentication bypass when the configured secret resolves to an empty string. The...
CVE-2026-53029
A flaw was found in the Linux kernel's ntfs3 filesystem driver. This vulnerability occurs due to an uninitialized local variable lcn when handling zero-length data during I/O operations. An attacker could potentially exploit this flaw to cause a denial of service or information disclosure due to...
