1) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2026-31826)

CWE-ID: CWE-770 - Allocation of Resources Without Limits or Throttling

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to allocation of resources without limits or throttling in the content stream parser when parsing a PDF content stream with a manipulated /Length value. A remote attacker can craft a PDF with a large /Length value to cause a denial of service.

This issue primarily affects cases where the library reads from buffers of unknown size, such as file objects opened in binary mode.
