Parameter "path" causes "500 Internal Server Error" on Commits REST endpoint

'path' parameter is not properly filtered in Rest API endpoint /rest/api/1.0/projects/{project_name}/repos/{repo_name}/commits, causing 500 internal server error. This is probably because that 'path' parameter is not properly filtered. The error can be reproduced by either of the following methods: (note in both cases the extra single quote at the end)

1. GET request on: BITBUCKET_BASE_URL/rest/api/1.0/projects/{TEST}/repos/{test}/commits/test_string' or;
2. GET request on: BITBUCKET_BASE_URL/rest/api/1.0/projects/{TEST}/repos/{test}/commits
   with parameters {"path": "test_string'"}
