CVE-2026-82398

A flaw was found in pypdf. An attacker can craft a PDF that causes long runtimes when the readuntilwhitespace function processes a stream containing a long sequence of bytes without whitespace. This occurs due to inefficient algorithmic complexity, where the function repeatedly performs immutable...
