R Programming Vulnerability: A Gateway to Supply Chain Attacks, here is a quick look

In a recent development, a new vulnerability in the R programming language has been discovered, exposing projects to potential supply chain attacks.

The Unveiling

Security researchers at HiddenLayer have unearthed a vulnerability in the R programming language that allows for arbitrary code execution. This vulnerability, known as CVE-2024-27322, has a CVSS vulnerability-severity score of 8.8 out of 10.

The Mechanism of R Programming Vulnerability

The vulnerability lies in R’s deserialization process, which is used for creating and loading R Data Serialization (RDS) files. An attacker can exploit this vulnerability by creating a promise object with an instruction that sets the variable to an unbound value and an expression containing arbitrary code. Due to R’s lazy evaluation, the expression is evaluated and run only when the symbol associated with the RDS file is accessed.

The Implications of R Programming Vulnerability

This vulnerability can be exploited through the loading of RDS files or R packages, which are often shared between developers and data scientists. An attacker can create malicious RDS files or R packages containing embedded arbitrary R code that executes on the victim’s target device upon interaction.

Impact on Open-Source Community

The open-source community, which thrives on the sharing and collaboration of code, is particularly vulnerable to such supply chain attacks. The discovery of this vulnerability in a widely used language like R could shake the trust within the community. It might lead to more stringent checks and balances before incorporating shared code or packages.

Risk to Individual Developers and Data Scientists

Individual developers and data scientists who frequently share and use R packages could inadvertently download and execute malicious code on their systems. This could lead to unauthorized access to their systems, loss of data, and potential misuse of their resources for further attacks.

The Aftermath of R Programming Vulnerability

The maintainers of R have addressed the issue in R version 4.4.0 after HiddenLayer informed them of the issue. However, the discovery of this vulnerability shows the potential risks associated with the use of open-source programming languages and the need for rigorous security measures.


This incident serves as a stark reminder of the importance of maintaining robust security practices in the realm of programming. It highlights the need for constant vigilance and proactive measures to identify and mitigate potential vulnerabilities. As the use of open-source programming languages continues to grow, so does the need for comprehensive security measures to protect against potential supply chain attacks.
