      <title>CVE-2026-34966 — Gitea prior to 1.27.0 SSRF via Migration URI Fetch Bypass</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-34966</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Gitea&lt;/p&gt;
&lt;p&gt;Gitea prior to 1.27.0 contains a server-side request forgery vulnerability that allows authenticated attackers to bypass SSRF protections by exploiting HTTP fetch operations in migration and OAuth avatar code paths that use Go&amp;#39;s default http.Get without a custom DialContext. Attackers can supply arbitrary URLs through release asset download URLs, pull-request patch URLs, or OAuth avatar endpoints to reach internal services, cloud instance-metadata endpoints, or read local files such as the application configuration containing database credentials and signing secrets, with exfiltrated content persisted as migration release assets for later retrieval.&lt;/p&gt;</description>
