pypdf: pypdf is a free and open-source pure-python PDF library
CVE-2026-102995 is fixed in pypdf on 1 platform by DEBIAN-CVE-2026-102995 (version 6.19.0-1), released October 4, 2026. It is not reported as exploited. Patch Radar priority: High.
pypdf is a free and open-source pure-python PDF library. Prior to 6.18.1, a crafted PDF can place unusually large source-code or destination-string tokens in a font /ToUnicode mapping, causing pypdf/_cmap.py parse_bfchar to decode and retain oversized values during operations such as text extraction and consume excessive memory. This is a second follow-up to earlier /ToUnicode resource-consumption fixes and is limited to the remaining token-length path. This issue is fixed in version 6.18.1.
