CVE-2026-45829: CWE-94: Improper Control of Generation of Code ('Code Injection') in Chroma ChromaDB
CVE-2026-45829 is a critical code injection vulnerability in ChromaDB version 1. 0. 0 and later. It allows an unauthenticated attacker to execute arbitrary code on the server by sending a malicious model repository with the parameter trust_remote_code set to true via a specific API endpoint. The vulnerability does not require any privileges or user interaction to exploit. No official patch or remediation guidance is currently available from the vendor. The vulnerability has a CVSS 4. 0 base score of 10, indicating maximum severity.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-45829) in ChromaDB arises from improper control of code generation (CWE-94). Specifically, when the trust_remote_code parameter is enabled (set to true) in the /api/v2/tenants/{tenant}/databases/{db}/collections endpoint, an attacker can submit a malicious model repository that leads to arbitrary code execution on the server without authentication. This affects ChromaDB Python project version 1.0.0 and later. The vulnerability is remotely exploitable over the network with no required privileges or user interaction, resulting in a critical security risk.
Potential Impact
Successful exploitation allows unauthenticated remote attackers to execute arbitrary code on the affected server, potentially leading to full system compromise. Given the critical CVSS score of 10 and the lack of required privileges or user interaction, this vulnerability poses a severe risk to confidentiality, integrity, and availability of the affected system.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, it is recommended to avoid enabling the trust_remote_code parameter or restrict access to the vulnerable API endpoint to trusted users only. Monitor vendor communications closely for updates on patches or official mitigations.
