### Impact

An attacker who uses this vulnerability can craft a PDF which leads to large memory usage. This requires loading images where the declared size values are much too large compared to the actual data.

### Patches

This has been fixed in [pypdf==6.14.0](https://github.com/py-pdf/pypdf/releases/tag/6.14.0).

### Workarounds

If you cannot upgrade yet, consider applying the changes from PR [#3888](https://github.com/py-pdf/pypdf/pull/3888).

CVE-2026-59938 describes a vulnerability in the pypdf library used by pdfly, where an attacker can create a PDF file with image dimension declarations that are significantly larger than the actual image data. When such a PDF is loaded, it leads to large memory consumption. This flaw has been fixed in pypdf version 6.14.0. A temporary workaround is available by applying the changes from pull request #3888 if upgrading is not feasible.

Psutils: pypdf: Possible large memory usage for wrong image dimensions (CVE-2026-59938)

pypdf is a free and open-source pure-python PDF library. Prior to 6.14.0, an attacker can craft a PDF with declared image size values that are much too large compared to the actual data, causing large memory usage in pypdf image parsing. This issue is fixed in version 6.14.0.

CVE-2026-59938 is a memory allocation vulnerability (CWE-789) in the pypdf library, a pure-Python PDF processing tool. Versions before 6.14.0 do not properly validate declared image size values in PDFs, allowing an attacker to specify image dimensions much larger than the actual data. This discrepancy leads to excessive memory usage during image parsing, potentially impacting application stability or availability. The vulnerability has a CVSS 4.0 base score of 6.9 (medium severity). The issue is resolved in pypdf version 6.14.0.
