CVE-2026-84309
pypdf is a free and open-source pure-python PDF library. Prior to 6.16.0, an attacker can craft a PDF whose cyclic tree structure causes pypdf/generic/datastructures.py TreeObject.insertchild to follow /Next links indefinitely when a writing code path inserts a child, producing an infinite loop...
CVE-2026-84309 pypdf: Possible infinite loop for TreeObject.insert_child
pypdf is a free and open-source pure-python PDF library. Prior to 6.16.0, an attacker can craft a PDF whose cyclic tree structure causes pypdf/generic/datastructures.py TreeObject.insertchild to follow /Next links indefinitely when a writing code path inserts a child, producing an infinite loop...
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...
