pypdf: pypdf is a free and open-source pure-python PDF library
CVE-2026-119207 is fixed in 2 products on 1 platform, first by DEBIAN-CVE-2026-119207, 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 memory when strict mode loads a crafted invalid PDF dictionary. Nested parsing failures add repeated exception text to newly raised errors, allowing a small malformed dictionary to amplify into very large error messages. This issue is fixed in version 6.21.3.
