| Package | Affected versions | Patched versions |
|---|---|---|
| io.jenkins.plugins:aws-sam | < 1.2.3 | 1.2.3 |
| amazon web services serverless application model | ≤ 1.2.2 |
AWS SAM Plugin 1.2.2 and earlier does not configure its YAML parser to prevent the instantiation of arbitrary types. This results in a remote code execution (RCE) vulnerability exploitable by users able to configure a job or control the contents of a previously configured "AWS SAM deploy application" build step’s YAML SAM template file (template.yaml or equivalent) file.
AWS SAM Plugin 1.2.3 configures its YAML parser to only instantiate safe types.
