CVE-2026-102999 is fixed in pypdf on 1 platform by DEBIAN-CVE-2026-102999 (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 6.19.0, a crafted PDF containing many embedded files can cause the dictionary-based attachments API in pypdf/_doc_common.py to reparse the full attachment list for each content lookup, producing repeated work and long runtimes when an application accesses the embedded-file mapping. This issue is fixed in version 6.19.0.
