{"id":"CVE-2026-33010","summary":"mcp-memory-service's Wildcard CORS with Credentials Enables Cross-Origin Memory Theft","details":"mcp-memory-service is an open-source memory backend for multi-agent systems. Prior to version 10.25.1, when the HTTP server is enabled (MCP_HTTP_ENABLED=true), the application configures FastAPI's CORSMiddleware with allow_origins=['*'], allow_credentials=True, allow_methods=[\"*\"], and allow_headers=[\"*\"]. The wildcard Access-Control-Allow-Origin: * header permits any website to read API responses cross-origin. When combined with anonymous access (MCP_ALLOW_ANONYMOUS_ACCESS=true) - the simplest way to get the HTTP dashboard working without OAuth - no credentials are needed, so any malicious website can silently read, modify, and delete all stored memories. This issue has been patched in version 10.25.1.","aliases":["GHSA-g9rg-8vq5-mpwm"],"modified":"2026-04-10T05:43:06.701006Z","published":"2026-03-20T18:33:39.007Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-942"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33010.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33010.json"},{"type":"ADVISORY","url":"https://github.com/doobidoo/mcp-memory-service/security/advisories/GHSA-g9rg-8vq5-mpwm"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-33010"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/doobidoo/mcp-memory-service","events":[{"introduced":"0"},{"fixed":"91ab4e5ee99d593d9b4400aac1f5e28232d4ab54"}],"database_specific":{"versions":[{"introduced":"0"},{"fixed":"10.25.1"}]}}],"versions":["v0.1.0","v1.0.0","v10.0.0","v10.0.1","v10.0.2","v10.0.3","v10.1.0","v10.1.1","v10.1.2","v10.10.0","v10.10.1","v10.10.2","v10.10.3","v10.10.4","v10.10.5","v10.10.6","v10.11.0","v10.11.1","v10.11.2","v10.12.0","v10.12.1","v10.13.0","v10.13.1","v10.13.2","v10.14.0","v10.15.0","v10.15.1","v10.16.0","v10.16.1","v10.17.0","v10.17.10","v10.17.11","v10.17.12","v10.17.13","v10.17.15","v10.17.16","v10.17.2","v10.17.3","v10.17.4","v10.17.5","v10.17.6","v10.17.7","v10.17.8","v10.17.9","v10.18.0","v10.18.1","v10.18.2","v10.18.3","v10.19.0","v10.2.0","v10.2.1","v10.20.0","v10.20.1","v10.20.2","v10.20.4","v10.20.6","v10.21.0","v10.21.1","v10.22.0","v10.23.0","v10.24.0","v10.25.0","v10.3.0","v10.4.0","v10.4.1","v10.4.2","v10.4.3","v10.4.4","v10.4.5","v10.4.6","v10.5.0","v10.5.1","v10.6.0","v10.6.1","v10.7.0","v10.7.1","v10.7.2","v10.8.0","v10.9.0","v2.0.0","v2.1.0","v2.2.0","v3.0.0","v3.1.0","v3.2.0","v3.3.0","v3.3.1","v3.3.2","v3.3.4","v4.0.0","v4.0.0-alpha.1","v4.0.0-beta.1","v4.2.0","v4.3.0","v4.5.0","v4.5.1","v4.5.2","v4.6.0","v4.6.1","v5.0.0","v5.0.1","v5.0.2","v5.0.3","v5.0.4","v5.0.5","v5.1.0","v5.2.0","v5.2.1","v5.3.0","v6.0.0","v6.1.0","v6.1.1","v6.10.0","v6.10.1","v6.11.0","v6.11.1","v6.12.0","v6.13.0","v6.13.1","v6.13.2","v6.13.3","v6.13.4","v6.13.5","v6.13.6","v6.13.7","v6.13.8","v6.14.0","v6.15.0","v6.15.1","v6.16.0","v6.16.1","v6.17.0","v6.17.1","v6.17.2","v6.18.0","v6.19.0","v6.2.0","v6.2.1","v6.2.4","v6.2.5","v6.20.0","v6.20.1","v6.21.0","v6.22.0","v6.22.1","v6.23.0","v6.3.0","v6.3.1","v6.3.2","v6.3.3","v6.4.0","v6.5.0","v6.5.1","v6.6.0","v6.6.1","v6.6.2","v6.6.3","v6.6.4","v6.7.0","v6.7.1","v6.7.2","v6.8.0","v6.9.0","v7.0.0","v7.1.0","v7.1.3-main","v7.1.4","v7.5.1","v7.5.2","v8.10.0","v8.11.0","v8.12.0","v8.12.1","v8.13.0","v8.13.1","v8.13.2","v8.13.3","v8.13.4","v8.13.5","v8.14.0","v8.14.1","v8.14.2","v8.15.0","v8.15.1","v8.16.0","v8.16.1","v8.16.2","v8.17.0","v8.17.1","v8.18.0","v8.18.1","v8.18.2","v8.19.0","v8.19.1","v8.2.4","v8.20.0","v8.20.1","v8.21.0","v8.22.0","v8.22.1","v8.22.2","v8.23.0","v8.23.1","v8.24.1","v8.24.2","v8.24.3","v8.24.4","v8.25.0","v8.25.1","v8.25.2","v8.26.0","v8.27.0","v8.27.1","v8.27.2","v8.28.0","v8.28.1","v8.29.0","v8.3.0","v8.3.1","v8.30.0","v8.31.0","v8.32.0","v8.33.0","v8.34.0","v8.35.0","v8.36.0","v8.36.1","v8.37.0","v8.38.0","v8.38.1","v8.39.0","v8.39.1","v8.4.0","v8.4.1","v8.4.2","v8.4.3","v8.40.0","v8.41.0","v8.41.1","v8.41.2","v8.42.0","v8.42.1","v8.43.0","v8.44.0","v8.45.0","v8.45.1","v8.45.2","v8.45.3","v8.46.0","v8.46.1","v8.46.2","v8.46.3","v8.47.0","v8.47.1","v8.48.0","v8.48.1","v8.48.2","v8.48.3","v8.48.4","v8.49.0","v8.5.0","v8.5.1","v8.5.10","v8.5.11","v8.5.12","v8.5.13","v8.5.14","v8.5.2","v8.5.3","v8.5.4","v8.5.5","v8.5.6","v8.5.7","v8.5.8","v8.5.9","v8.50.0","v8.50.1","v8.51.0","v8.52.0","v8.52.1","v8.52.2","v8.53.0","v8.54.0","v8.54.1","v8.54.2","v8.54.3","v8.54.4","v8.55.0","v8.56.0","v8.57.0","v8.57.1","v8.58.0","v8.59.0","v8.6.0","v8.60.0","v8.61.0","v8.61.1","v8.61.2","v8.62.0","v8.62.1","v8.62.10","v8.62.11","v8.62.12","v8.62.13","v8.62.2","v8.62.3","v8.62.4","v8.62.5","v8.62.6","v8.62.7","v8.62.8","v8.62.9","v8.63.0","v8.63.1","v8.64.0","v8.65.0","v8.66.0","v8.67.0","v8.68.0","v8.68.1","v8.68.2","v8.69.0","v8.7.0","v8.70.0","v8.71.0","v8.72.0","v8.73.0","v8.74.0","v8.75.0","v8.75.1","v8.76.0","v8.8.0","v8.8.1","v8.8.2","v8.9.0","v9.0.0","v9.0.1","v9.0.2","v9.0.3","v9.0.4","v9.0.5","v9.0.6","v9.2.0","v9.2.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-33010.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N"}]}
