pypdf: pypdf is a free and open-source pure-python PDF library
CVE-2026-119204 is fixed in 2 products on 1 platform, first by DEBIAN-CVE-2026-119204, 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 6.21.4, pypdf can consume excessive memory while parsing a crafted PDF page tree containing many shared resources. Page-tree flattening copies page dictionary and inherited resource entries without a document-wide entry budget, allowing the crafted resource structure to cause disproportionate allocations. This issue is fixed in version 6.21.4.
