CVE-2025-54798
Description
A flaw was found in tmp. The tmp module, used for creating temporary files and directories in Node.js, allows an arbitrary temporary file or directory write due to insufficient validation of the symbolic link parameter. This vulnerability allows a local attacker to provide a crafted symbolic link. This issue allows the creation of temporary files or directories at attacker-specified locations, potentially leading to unexpected behavior.
Statement
This issue was rated as low because, while a symbolic link can be used to create files outside the intended temporary directory, exploitation requires local access and specific setup. The impact is limited to modifying files in specific locations, with no effect on sensitive information or system availability, which keeps the overall risk low.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.

Understanding the Weakness (CWE)
Confidentiality,Integrity,Access Control
Technical Impact: Read Files or Directories; Modify Files or Directories; Bypass Protection Mechanism
An attacker may be able to traverse the file system to unintended locations and read or overwrite the contents of unexpected files. If the files are used for a security mechanism then an attacker may be able to bypass the mechanism.
Other
Technical Impact: Execute Unauthorized Code or Commands
Windows simple shortcuts, sometimes referred to as soft links, can be exploited remotely since a ".LNK" file can be uploaded like a normal file. This can enable remote execution.
