Summary
A vulnerability has been discovered and fixed in Mesop that could potentially allow unauthorized access to files on the server hosting the Mesop application. The vulnerability was related to insufficient input validation in a specific endpoint. This could have allowed an attacker to access files not intended to be served.
Users are strongly advised to update to the latest version of Mesop immediately. The latest version includes a fix for this vulnerability.
We would like to thank @Letm3through for reporting this issue and proposing mitigations to address this issue.
Impact
The application does not adequately validate input before processing it, allowing unexpected values to reach sensitive code paths. Typical impact: varies by context: data corruption, logic bypass, or denial of service.
CVE-2024-45601 has a CVSS score of 7.5 (High). The vector is network-reachable, no privileges required, and no user interaction. 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 (0.12.4); 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-2024-45601? CVE-2024-45601 is a high-severity improper input validation vulnerability in mesop (pip), affecting versions >= 0.9.0, < 0.12.4. It is fixed in 0.12.4. The application does not adequately validate input before processing it, allowing unexpected values to reach sensitive code paths.
- How severe is CVE-2024-45601? CVE-2024-45601 has a CVSS score of 7.5 (High). 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 mesop are affected by CVE-2024-45601? mesop (pip) versions >= 0.9.0, < 0.12.4 is affected.
- Is there a fix for CVE-2024-45601? Yes. CVE-2024-45601 is fixed in 0.12.4. Upgrade to this version or later.
- Is CVE-2024-45601 exploitable, and should I be worried? Whether CVE-2024-45601 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-2024-45601 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-2024-45601? Upgrade
mesopto 0.12.4 or later.
