      <title>CVE-2026-25934 — go-git improperly verifies data integrity values for .idx and .pack files</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-25934</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; go-git&lt;/p&gt;
&lt;p&gt;go-git is a highly extensible git implementation library written in pure Go. Prior to 5.16.5, a vulnerability was discovered in go-git whereby data integrity values for .pack and .idx files were not properly verified. This resulted in go-git potentially consuming corrupted files, which would likely result in unexpected errors such as object not found. For context, clients fetch packfiles from upstream Git servers. Those files contain a checksum of their contents, so that clients can perform integrity checks before consuming it. The pack indexes (.idx) are generated locally by go-git, or the git cli, when new .pack files are received and processed. The integrity checks for both files were not being verified correctly. This vulnerability is fixed in 5.16.5.&lt;/p&gt;</description>
