      <title>CVE-2026-61640 — Wallos: SSRF via OIDC Token/UserInfo URL Configuration</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-61640</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; ellite Wallos&lt;/p&gt;
&lt;p&gt;Wallos is an open-source, self-hostable personal subscription tracker. Prior to version 4.9.6, Admin-configured OIDC token_url and user_info_url in includes/oidc/handle_oidc_callback.php:18-49 are used directly in curl_init() with zero SSRF filtering. Unlike logo/webhook URLs which have validate_webhook_url_for_ssrf(), OIDC URLs bypass all protections. Admin sets URL to http://169.254.169.254/latest/meta-data/ for cloud metadata access or internal network pivoting. This issue has been patched in version 4.9.6.&lt;/p&gt;</description>
