Prior to Python SDK 2.0.18 and TypeScript SDK 3.1.6, _build_session_scope() in mem0/memory/main.py and Memory.buildSessionScope() in the TypeScript SDK join caller-controlled user_id, agent_id, and run_id values using unescaped & and = delimiters. A caller can embed another scope component in a controlled identifier so that distinct tenant tuples produce the same session_scope key. Memory.add(), AsyncMemory.add(), and the REST POST /memories flow use that key to read and save recent raw messages, allowing cross-tenant conversation disclosure and eviction or interleaving of another tenant's history. This issue is fixed in Python SDK 2.0.18 and TypeScript SDK 3.1.6.","state":0,"publishedAt":"2026-10-26T21:18:13.36+00:00","modifiedAt":"2026-10-27T16:04:22.707+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:N","score":6.3,"severity":"MEDIUM"}],"references":["https://github.com/mem0ai/mem0/commit/71f2ebefa3494da21550fb525216818776cde67f","https://github.com/mem0ai/mem0/pull/6892","https://github.com/mem0ai/mem0/releases/tag/ts-v3.1.6","https://github.com/mem0ai/mem0/releases/tag/v2.0.18","https://github.com/mem0ai/mem0/security/advisories/GHSA-5324-3w58-qpp2"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-116575","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-200","CWE-863"],"productCriteria":[],"sourceDates":{"published":"2026-10-26T21:18:13.360","lastModified":"2026-10-27T16:04:22.707"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
