      <title>CVE-2026-77261 — MCP Atlassian: SSRF redirect protection missing for basic-auth and OAuth authentication branches</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-77261</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; sooperset mcp-atlassian&lt;/p&gt;
&lt;p&gt;MCP Atlassian is a Model Context Protocol (MCP) server for Atlassian products (Confluence and Jira). Prior to 0.22.0, _make_ssrf_safe_hook is omitted from JiraFetcher and ConfluenceFetcher sessions created through the basic-auth and oauth_pat branches. If an attacker-controlled or compromised configured Atlassian instance returns a redirect to an internal address, those sessions can follow the redirect without revalidating its destination. This issue is fixed in version 0.22.0.&lt;/p&gt;</description>
