BIT-PILLOW-2026-112895 Pillow: Unbounded recursion parsing a PDF page tree or trailer chain (incomplete fix for CVE-2026-42310)

Pillow is a Python imaging library. From 5.1.0 until 13.0.0, Pillow can exhaust resources while parsing an existing PDF during an append operation. PdfParser follows page-tree child references without cycle or duplication tracking and follows previous-trailer chains with only an exact...

BIT-PILLOW-2026-112391 Pillow: PdfParser can recurse without limit in get_value() and linearize_page_tree()

Pillow is a Python imaging library. From 5.1.0 until 13.0.0, Pillow's PdfParser.getvalue can recurse without a limit while reading nested PDF objects. The parser follows attacker-controlled arrays and dictionaries when an existing PDF is opened for append. An attacker can provide a deeply nested...

GHSA-254F-3936-288H Pillow: PdfParser can recurse without limit in get_value() and linearize_page_tree()

Summary PdfParser's getvalue can recurse without any limit and crash with an uncaught RecursionError. It is reachable through Image.saveim, fp=, format="PDF", append=True when the existing PDF file is attacker-controlled. This is the same class of bug as...
