pypdf: pypdf is a free and open-source pure-python PDF library
CVE-2026-119208 is fixed in 2 products on 1 platform, first by DEBIAN-CVE-2026-119208, released November 6, 2026. It is not reported as exploited. Patch Radar priority: Routine.
pypdf is a free and open-source pure-python PDF library. Prior to 6.21.3, pypdf can consume excessive time and memory when an application accesses the page count of a crafted encrypted PDF whose page tree declares a forged /Count value. Even after successful decryption, page-count retrieval trusts the unvalidated declared count instead of walking the page tree, allowing the attacker-controlled value to drive excessive work and memory use. This issue is fixed in version 6.21.3.
