QID 982892: Java (maven) Security Update for io.swagger:swagger-codegen (GHSA-hpv8-9rq5-hq7w)

Security update has been released for io.swagger:swagger-codegen to fix the vulnerability.

Note: The preceding description block is extracted directly from the security advisory. Using automation, we have attempted to clean and format it as much as possible without introducing additional issues.

**This vulnerability impacts generated code.** If this code was generated as a one-off occasion, not as a part of an automated CI/CD process, this code will remain vulnerable until fixed manually!

On Unix-Like systems, the system temporary directory is shared between all local users. When files/directories are created, the default `umask` settings for the process are respected. As a result, by default, most processes/apis will create files/directories with the permissions `-rw-r--r--` and `drwxr-xr-x` respectively, unless an API that explicitly sets safe file permissions is used.

CVSS V3 rated as Medium - 5.5 severity.

CVSS V2 rated as Low - 2.1 severity.

Solution

Fix has been applied to the master branch with:

* https://github.com/swagger-api/swagger-codegen/commit/35adbd552d5f99b3ff1e0e59da228becc85190f2

included in release: 2.4.19Workaround:
Users can remediate the vulnerability in non patched version by manually (or programmatically e.g. in CI) updating the generated source code to use `java.nio.files.Files` temporary file creation instead of `java.io.File`, e.g. by changing

```java

if (tempFolderPath == null)
return File.createTempFile(prefix, suffix);
else
return File.createTempFile(prefix, suffix, new File(tempFolderPath));

```

to

```java

if (tempFolderPath == null)
return Files.createTempFile(prefix, suffix).toFile();
else
return Files.createTempFile(Paths.get(tempFolderPath), prefix, suffix).toFile();

```

or generally changing:

```java

File.createTempFile(prefix, suffix);

```

to

```java

Files.createTempFile(prefix, suffix).toFile();

```
