Prior to v1.5.2, Serena's built-in web dashboard exposes an unauthenticated Flask API on a fixed, predictable port, with no authentication, no CSRF protection, and no Host header validation. A DNS rebinding attack allows a malicious webpage to reach this API from any browser and write arbitrary content to the agent's persistent memory store, which the agent reads and acts on autonomously. Combined with execute_shell_command using shell=True, this creates a remote code execution chain requiring only that the victim visit a malicious webpage while Serena is running. This issue is fixed in version v1.5.2."}], "lastModified": "2026-07-20T14:54:40.713", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:oraios-ai:serena:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "AF130475-F83E-48A2-A7D9-CBC5D574933F", "versionEndExcluding": "1.5.2"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
