CVE-2026-102996 is fixed in pypdf on 1 platform by DEBIAN-CVE-2026-102996 (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 provide a TrueType or Type1 simple font with an unusually large /Widths array, causing pypdf/_font.py Font._collect_tt_t1_character_widths to process entries beyond the 256 character codes meaningful for a simple font and consume excessive memory during operations such as text extraction. This issue is fixed in version 6.18.1.
