CVE-2026-49460

CVE-2026-49460 affects the Python PDF library pypdf . Prior to version 6.12.2 , processing a PDF that uses a stream with the /FlateDecode filter and a PNG predictor can cause unusually long runtimes. The issue is fixed in 6.12.2 . Impact, in line with the sources, is a denial of service-like slow...

pypdf: Inefficient decoding of FlateDecode PNG predictor streams

Impact 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. Patches This has been fixed in pypdf==6.12.2. Workarounds If you cannot upgrade yet, consider applying the changes...
