Summary
PraisonAI Vulnerable Untrusted Remote Template Code Execution
Impact
This vulnerability allows execution of untrusted code from remote templates, leading to potential compromise of the user’s environment.
An attacker can:
- Access sensitive data (API keys, tokens, credentials)
- Execute arbitrary commands with user privileges
- Establish persistence or backdoors on the system
This is particularly dangerous in:
- CI/CD pipelines
- Shared development environments
- Systems running untrusted or third-party templates
Successful exploitation can result in data theft, unauthorized access to external services, and full system compromise.
CVE-2026-40154 has a CVSS score of 9.3 (Critical). The vector is network-reachable, no privileges required, and user interaction required. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (4.5.128); upgrading removes the vulnerable code path.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions
- What is CVE-2026-40154? CVE-2026-40154 is a critical-severity security vulnerability in PraisonAI (pip), affecting versions < 4.5.128. It is fixed in 4.5.128.
- How severe is CVE-2026-40154? CVE-2026-40154 has a CVSS score of 9.3 (Critical). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
- Which versions of PraisonAI are affected by CVE-2026-40154? PraisonAI (pip) versions < 4.5.128 is affected.
- Is there a fix for CVE-2026-40154? Yes. CVE-2026-40154 is fixed in 4.5.128. Upgrade to this version or later.
- Is CVE-2026-40154 exploitable, and should I be worried? Whether CVE-2026-40154 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2026-40154 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
- How do I fix CVE-2026-40154? Upgrade
