Medium [CVE-2026-49460] Denial of Service via crafted PDF with FlateDecode filter
CVE-2026-49460Source published Jun 22, 2026Source updated Jun 22, 2026
pypdf is a free and open-source pure-python PDF library. Prior to 6.12.2, an attacker who uses this vulnerability can craft a PDF which leads to long runtimes. This requires accessing a stream which uses the /FlateDecode filter with a PNG predictor. This vulnerability is fixed in 6.12.2. A flaw was found in pypdf (before 6.12.2). pypdf is vulnerable to denial of service when parsing a crafted PDF containing a /FlateDecode stream with a PNG predictor. An attacker who can supply such a document for processing may cause the application to hang on long runtimes. Red Hat exposure is in Python services that use pypdf for PDF ingestion, including Quay, OpenShift logging/observability tooling, and other containerized apps that bundle the library for document handling. Red Hat severity: Moderate…
