      <title>CVE-2026-52886 — Notepad++: session.xml backupFilePath starts_with Bypass</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-52886</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; notepad-plus-plus&lt;/p&gt;
&lt;p&gt;Notepad++ is a free and open-source source code editor. Prior to 8.9.7, Notepad++ validates the backupFilePath attribute from session.xml with std::wstring::starts_with against the expected backup directory without path normalization, allowing parent-directory sequences during snapshot-mode restoration to read an arbitrary user-readable file outside the backup directory into an editor tab. This issue is fixed in version 8.9.7.&lt;/p&gt;</description>
