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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-942"],"references":["https://github.com/doobidoo/mcp-memory-service/security/advisories/GHSA-g9rg-8vq5-mpwm","https://github.com/doobidoo/mcp-memory-service/security/advisories/GHSA-g9rg-8vq5-mpwm"],"products":["doobidoo:mcp-memory-service"],"source":"nvd","synced_at":"2026-10-19T22:26:19.218427112+00:00"},"epss":{"cve":"CVE-2026-33010","score":0.00394,"percentile":0.33644,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-g9rg-8vq5-mpwm","url":"https://osv.dev/vulnerability/GHSA-g9rg-8vq5-mpwm","summary":"mcp-memory-service's Wildcard CORS with Credentials Enables Cross-Origin Memory Theft","modified":"2026-07-13T16:42:58.062363435Z","packages":[{"ecosystem":"PyPI","name":"mcp-memory-service","purl":"pkg:pypi/mcp-memory-service","ranges":["<10.25.1"],"fixed":["10.25.1"]}]},{"id":"PYSEC-2026-2625","url":"https://osv.dev/vulnerability/PYSEC-2026-2625","summary":"mcp-memory-service's Wildcard CORS with Credentials Enables Cross-Origin Memory Theft","modified":"2026-07-13T16:32:13.301820998Z","packages":[{"ecosystem":"PyPI","name":"mcp-memory-service","purl":"pkg:pypi/mcp-memory-service","ranges":["<10.25.1"],"fixed":["10.25.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
