CVE-2026-28351

Manipulated RunLengthDecode streams can exhaust RAM

CVSS 6.9 MEDIUMEPSS 0.4%CWE-400
pypdf is a free and open-source pure-python PDF library. Prior to version 6.7.4, an attacker who uses this vulnerability can craft a PDF which leads to large memory usage. This requires parsing the content stream using the RunLengthDecode filter. This has been fixed in pypdf 6.7.4. As a workaround, consider applying the changes from PR #3664.
