CVE-2026-31245: n/a
The mem0 1.0.0 server has a vulnerability in its memory creation API endpoint (POST /memories) due to lack of authentication and authorization controls. This allows unauthenticated remote attackers to submit arbitrary memory records without identity or permission verification, potentially injecting unauthorized or malicious data into the database. The vulnerability is rated medium severity with a CVSS score of 5.3. No official patch or remediation guidance is currently available, and no known exploits have been reported in the wild.
AI Analysis
Technical Summary
CVE-2026-31245 describes a vulnerability in mem0 version 1.0.0 where the POST /memories API endpoint does not enforce authentication or authorization. This allows remote attackers to create arbitrary memory entries without any identity verification, leading to unauthorized data injection and potential data pollution. The issue corresponds to CWE-306 (Missing Authentication) and CWE-862 (Missing Authorization). The CVSS 3.1 base score is 5.3, reflecting a medium severity with network attack vector, low attack complexity, no privileges required, no user interaction, and impact limited to integrity loss without confidentiality or availability impact. There is no vendor advisory or patch available at this time.
Potential Impact
An unauthenticated remote attacker can submit arbitrary memory records to the mem0 server, resulting in unauthorized data injection and potential pollution of the database. This compromises data integrity but does not affect confidentiality or availability. No known exploits have been reported in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, consider implementing external access controls or network-level restrictions to limit access to the vulnerable API endpoint. Monitor for unusual or unauthorized data entries as a precaution.
