CVE-2026-84311
pypdf , a pure-Python PDF library, is vulnerable to a denial-of-service condition in versions prior to 6.16.1 . A crafted PDF can trigger exponential traversal in PageObject._extract_text and PageObject.extract_xform_text (in pypdf/_page.py) by invoking a directed acyclic graph of reused form XOb...
CVE-2026-84311 pypdf: Possible long runtimes/large memory usage when extracting XForm objects
pypdf is a free and open-source pure-python PDF library. Prior to 6.16.1, an attacker can craft a PDF that causes pypdf/page.py PageObject.extracttext and PageObject.extractxformtext to traverse a directed acyclic graph of reused form XObjects in which each form invokes a child multiple times,...

CVE-2026-84310
pypdf , a pure-Python PDF library, is vulnerable to denial-of-service via crafted PDFs. The vulnerable component is the _get_outline function in pypdf/_doc_common.py, which lacks global entry-count and nesting-depth limits during outline traversal. A malicious PDF with a large number of outline e...
