Critical-only feed available.enhttps://vulnfeed.org/cve/CVE-2026-119206/https://vulnfeed.org/cve/CVE-2026-119206/Thu, 29 Oct 2026 20:37:15 +0000pypdf 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.https://vulnfeed.org/cve/CVE-2026-115580/https://vulnfeed.org/cve/CVE-2026-115580/Fri, 23 Oct 2026 20:17:21 +0000pypdf is a free and open-source pure-python PDF library. Prior to 6.21.2, an attacker can craft a PDF with a standard cross-reference table whose declared entry count exceeds what the file can contain, causing excessive processing and long runtimes when the file is opened. This issue is fixed in version 6.21.2.https://vulnfeed.org/cve/CVE-2026-115585/https://vulnfeed.org/cve/CVE-2026-115585/Fri, 23 Oct 2026 20:17:21 +0000pypdf is a free and open-source pure-python PDF library. Prior to 6.21.2, an incomplete remediation for repeated malformed cross-reference entries in GHSA-55h5-xmcq-c37v could still trigger a complete PDF stream reload during each recovery attempt even when a recovery cache was present, causing crafted cross-reference streams to produce long runtimes. This issue is fixed in version 6.21.2.https://vulnfeed.org/cve/CVE-2026-115572/https://vulnfeed.org/cve/CVE-2026-115572/Fri, 23 Oct 2026 20:17:20 +0000pypdf is a free and open-source pure-python PDF library. Prior to 6.21.2, an attacker can craft a PDF that repeatedly references the same nonexistent indirect object, causing relevant file parts such as pages to trigger repeated full-file recovery loads and long runtimes when accessed. This issue is fixed in version 6.21.2.
