      <title>BREW-pdfalyzer-CVE-2026-59937 — pypdf: Possible long runtimes for repeated malformed cross-reference entries</title>
      <link>https://cve.radiocsirt.org/vuln/brew-pdfalyzer-cve-2026-59937</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Homebrew: pdfalyzer&lt;/p&gt;
&lt;p&gt;### Impact&lt;/p&gt;
&lt;p&gt;An attacker who uses this vulnerability can craft a PDF which leads to long runtimes. This requires cross-reference streams with repeated malformed cross-reference streams.&lt;/p&gt;
&lt;p&gt;### Patches&lt;/p&gt;
&lt;p&gt;This has been fixed in [pypdf==6.14.0](https://github.com/py-pdf/pypdf/releases/tag/6.14.0).&lt;/p&gt;
&lt;p&gt;### Workarounds&lt;/p&gt;
&lt;p&gt;If you cannot upgrade yet, consider applying the changes from PR [#3887](https://github.com/py-pdf/pypdf/pull/3887).&lt;/p&gt;</description>

      <link>https://cve.radiocsirt.org/vuln/cve-2026-59937</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; py-pdf pypdf&lt;/p&gt;
&lt;p&gt;pypdf is a free and open-source pure-python PDF library. Prior to 6.14.0, an attacker can craft a PDF with repeated malformed cross-reference streams that cause pypdf to spend long runtimes recovering broken cross-reference table entries. This issue is fixed in version 6.14.0.&lt;/p&gt;</description>
