      <title>BREW-adr-viewer-CVE-2026-115355 — Mistune: Path Traversal and XSS in Include directive</title>
      <link>https://db.gcve.eu/vuln/brew-adr-viewer-cve-2026-115355</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Homebrew: adr-viewer&lt;/p&gt;
&lt;p&gt;The Include directive in `src/mistune/directives/include.py` does not validate that the resolved file path stays within the source directory, allowing path traversal via `../` sequences to read arbitrary files.&lt;/p&gt;
&lt;p&gt;Additionally, error messages and included file contents are rendered without HTML escaping, leading to XSS even when `escape=True`.&lt;/p&gt;
&lt;p&gt;Affected functions:
- Path resolution (lines 27-31)
- `block_error()` in html.py (line 140)
- `render_html_include()` (line 72)&lt;/p&gt;
&lt;p&gt;The Include plugin must be explicitly enabled via the plugins parameter.&lt;/p&gt;</description>

      <title>CVE-2026-115355 — Mistune before 3.3.0 Path Traversal and XSS via Include Directive</title>
      <link>https://db.gcve.eu/vuln/cve-2026-115355</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; lepture mistune&lt;/p&gt;
&lt;p&gt;Mistune before 3.3.0 contains a path traversal vulnerability in the Include directive that allows attackers to read arbitrary files by supplying ../ sequences in include paths. Attackers can also inject HTML through unescaped error messages and included file contents to perform cross-site scripting even when escape=True is set.&lt;/p&gt;</description>
