waiting for further signalsZero needs more public information before it can validate it.GHSA-qv6h-rv94-w285 ↗EUVD-2026-90365 ↗
description
pypdf versions before 6.17.0 can consume excessive memory while handling page labels in a crafted PDF. An attacker may make an application unavailable if it processes the document's page labels; exploitation requires the application to retrieve those labels.
mitigation
Upgrade pypdf to version 6.17.0 or later. Until upgrading, avoid retrieving page labels from untrusted PDFs and apply the upstream corrective change if feasible.
fixed in 6.17.0
outcome
Contextual: an exploit technique exists, but no deterministic check could cover this one.
