When processing an encrypted PDF file after successful decryption, the get_num_pages() method fails to verify whether the encryption handler has already unlocked the document. Consequently, pypdf returns the unvalidated /Count integer directly from the /Pages catalog dictionary instead of traversing and flattening the actual page tree. Attackers can supply an encrypted PDF with an artificially inflated /Count attribute to trigger excessive memory allocation and prolonged CPU usage during downstream operations such as page iteration or label resolution.\n\n## TL;DR\nVersions of pypdf prior to 6.21.3 trust the unvalidated /Count metadata in encrypted PDFs even after decryption, enabling attackers to trigger memory exhaustion and CPU starvation via forged page counts.\n\n## Exploit Status: POC\n\n## Technical Details\n\n- **Vulnerability Type**: CWE-400: Uncontrolled Resource Consumption\n- **Attack Vector**: Network (Crafted Encrypted PDF File)\n- **CVSS v4.0 Score**: 7.1 High (AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:H)\n- **EPSS Score**: 0.30% (23.18th Percentile)\n- **Affected Component**: PdfDocCommon.get_num_pages() in pypdf/_doc_common.py\n- **Impact**: Denial of Service via Memory Exhaustion & CPU Lockup\n- **Exploit Status**: Proof-of-Concept Available (Unit Test Reproduction)\n- **Patched Version**: pypdf 6.21.3\n\n## Affected Systems\n\n- pypdf (Python Package Index / PyPI)\n- **pypdf**: < 6.21.3 (Fixed in: `6.21.3`)\n\n## Mitigation\n\n- Upgrade pypdf to version 6.21.3 or later to ensure decrypted documents validate page counts by flattening the page tree.\n- Enforce process-level memory limits (cgroups, ulimit, or resource.setrlimit) on worker processes handling untrusted PDF parsing.\n- Implement strict execution timeouts on background jobs and request handlers that ingest and decrypt PDF documents.\n- Explicitly invoke internal page tree flattening after decryption if running on legacy versions that cannot be immediately upgraded.\n\n**Remediation Steps:**\n1. Audit application dependencies (requirements.txt, pyproject.toml, Pipfile.lock) to identify installations of pypdf prior to 6.21.3.\n2. Run `pip install --upgrade \"pypdf>=6.21.3\"` across affected environments and rebuild deployment containers.\n3. Verify that unit and integration tests pass, specifically confirming that encrypted PDF workflows properly invoke `reader.decrypt()` prior to accessing page counts or labels.\n4. Configure worker orchestration frameworks (such as Celery or Kubernetes pods) with appropriate memory limits and task timeouts.\n\n## References\n\n- [GitHub Security Advisory GHSA-62m5-6wh8-28x7](https://github.com/py-pdf/pypdf/security/advisories/GHSA-62m5-6wh8-28x7)\n- [GitHub Pull Request #4270: SEC: Use the validated page count after decrypting a document](https://github.com/py-pdf/pypdf/pull/4270)\n- [Fix Commit 82b91951dc74496bb3efe6465434f041bb6a5e6b](https://github.com/py-pdf/pypdf/commit/82b91951dc74496bb3efe6465434f041bb6a5e6b)\n- [pypdf Release 6.21.3](https://github.com/py-pdf/pypdf/releases/tag/6.21.3)\n- [National Vulnerability Database (NVD) -
