CVE-2025-27098 Vulnerability Summary

CVE-2025-27098: GraphQL Mesh is a GraphQL Federation framework and gateway for both GraphQL Federation and non-GraphQL Federation subgraphs, non-GraphQL services, such as REST and gRPC, and also databases such as MongoDB, MySQL, and PostgreSQL. Missing check vulnerability in the static file handler allows any client to access the files in the server's file system. When `staticFiles` is set in the `serve` settings in the configuration file, the following handler doesn't check if `absolutePath` is still under the directory provided as `staticFiles`. Users have two options to fix vulnerability; 1. Update `@graphql-mesh/cli` to a version higher than `0.82.21`, and if you use `@graphql-mesh/http`, update it to a version higher than `0.3.18` 2. Remove `staticFiles` option from the configuration, and use other solutions to serve static files.

Assessing the Risk of CVE-2025-27098

Access Complexity Graph

The exploitability of CVE-2025-27098 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).

Exploitability Analysis for CVE-2025-27098

CVE-2025-27098 presents a challenge to exploit due to its high attack complexity, but the absence of privilege requirements still makes it a viable target for skilled attackers. A thorough security review is advised.

Understanding AC and PR

A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.

Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.

Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.

CVSS Score Breakdown Chart

Above is the CVSS Sub-score Breakdown for CVE-2025-27098, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.

CIA Impact Analysis

Below is the Impact Analysis for CVE-2025-27098, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.

  • Confidentiality: Low
    CVE-2025-27098 could lead to minor leaks of non-critical information without major privacy breaches.
  • Integrity: Low
    Exploiting CVE-2025-27098 may cause minor changes to data without severely impacting its accuracy.
  • Availability: Low
    CVE-2025-27098 may slightly degrade system performance without fully affecting service availability.

Exploit Prediction Scoring System (EPSS)

The EPSS score estimates the probability that this vulnerability will be exploited in the near future.

EPSS Score: 0.087% (probability of exploit)

EPSS Percentile: 39.51% (lower percentile = lower relative risk)
This vulnerability is less risky than approximately 60.49% of others.
