CVE-2026-59935 is an infinite-loop vulnerability in pypdf versions earlier than 6.14.2. A crafted PDF page content stream containing a non-terminated inline image encoded with an ASCII85 or ASCIIHex filter can cause the library's content-stream parser to loop indefinitely. The condition can be triggered during PDF-processing operations such as page text extraction.
