pypdf: pypdf is a free and open-source pure-python PDF library
CVE-2026-119206 is fixed in 2 products on 1 platform, first by DEBIAN-CVE-2026-119206, 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 take excessive time to retrieve page labels from a crafted PDF containing a flat page-label number tree with many ranges. The page_labels property resolves each page independently and repeatedly scans the same /Nums array from the beginning, causing work to grow with both the page count and the number of label ranges. This issue is fixed in version 6.21.3.
