pypdf: Inefficient handling of non-whitespace inputs in readuntilwhitespace...

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...

CVE-2026-82398

pypdf is a free and open-source pure-python PDF library. Prior to 6.15.0, an attacker can craft a PDF that causes long runtimes when the pypdf/utils.py function readuntilwhitespace reads a stream containing a long run of bytes without whitespace. The function repeatedly performs immutable bytes...

CVE-2026-82398

pypdf , a pure-Python PDF library, is vulnerable to excessive resource consumption in the read_until_whitespace function within pypdf/_utils.py. When processing a crafted PDF containing a long sequence of non-whitespace bytes, the function performs immutable bytes concatenation in a one-byte loop...
