pypdf: pypdf is a free and open-source pure-python PDF library
CVE-2026-115585 is fixed in pypdf on 1 platform by DEBIAN-CVE-2026-115585 (version 6.21.4-1), 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 6.21.2, 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.
