description

pypdf versions earlier than 6.18.0 may consume excessive time while parsing malformed PDF object metadata, which can make applications unavailable. Exploitation requires an application to process an attacker-controlled PDF.

mitigation

Upgrade pypdf to >= 6.18.0 or later.

fixed in >= 6.18.0
