CVE-2026-84310 is fixed in pypdf on 1 platform by DEBIAN-CVE-2026-84310 (version 6.19.0-1), released September 1, 2026. It is not reported as exploited. Patch Radar priority: Routine.
pypdf is a free and open-source pure-python PDF library. Prior to 6.16.1, an attacker can craft a PDF that causes pypdf/_doc_common.py _get_outline to consume long runtimes and large amounts of memory when retrieving document outlines with large numbers of entries or deeply nested reused paths because the traversal lacked global entry-count and nesting-depth limits. This issue is fixed in version 6.16.1.
