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":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:N","score":6.3,"severity":null}],"references":["https://github.com/mem0ai/mem0/security/advisories/GHSA-5324-3w58-qpp2","https://github.com/mem0ai/mem0/pull/6892","https://github.com/mem0ai/mem0/commit/71f2ebefa3494da21550fb525216818776cde67f","https://github.com/mem0ai/mem0/releases/tag/ts-v3.1.6","https://github.com/mem0ai/mem0/releases/tag/v2.0.18"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-110315","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Oct 26, 2026, 8:15:01 PM","dateUpdated":"Oct 27, 2026, 2:18:25 PM"},"relatedAdvisories":[],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
