    <html>
    <body>
    <video id="myVideo" controls>
    <source src="malicious.mp4" type="video/mp4">
    </video>
    <script>
    var video = document.getElementById("myVideo");
    video.oncanplaythrough = function() {
    video.play();
    // Trigger 'use after free' condition in Media Stream here
    };
    </script>

    How the Exploit Works

    The exploit takes advantage of a vulnerability in the GitHub workflow of the dedupe library. Specifically, it manipulates the issue_comment to trigger an event using the @benchmark body. This event then checks out the manipulated PR’s branch, which may contain untrusted code. When this code is executed, it can lead to the exfiltration of GITHUB_TOKEN, a token with write permissions on most scopes, which could potentially lead to a repository takeover.

    Conceptual Example Code

    While the exact execution will depend on the specific untrusted code inserted into the PR branch, a conceptual example of how the vulnerability might be exploited could look like this:

    POST /repos/:owner/:repo/issues/:issue_number/comments HTTP/1.1
    Host: api.github.com
    Authorization: token GITHUB_TOKEN
    Content-Type: application/json
    {
    "body": "@benchmark"
    }

    In this example, the malicious actor uses the POST method to insert a comment with the @benchmark body. This triggers the GitHub Actions workflow, which could execute the untrusted code and potentially lead to the exfiltration of the GITHUB_TOKEN.
    Fortunately, this vulnerability has been fixed by commit 3f61e79. As a cybersecurity expert, I strongly recommend applying the vendor patch or using a WAF/IDS as temporary mitigation to prevent potential system compromise or data leakage.

    How the Exploit Works

    The vulnerability CVE-2025-43273 arises from a flaw in the sandbox implementation of macOS Sequoia 15.6. A sandbox is a secure environment that isolates running processes to limit the resources they can access. However, due to a permissions issue in this version of the OS, a malicious process running within the sandbox can circumvent these restrictions. It can potentially gain unauthorized access to system resources or even execute privileged operations, leading to system compromise or data leakage.

    Conceptual Example Code

    Here is a conceptual example of how the vulnerability might be exploited using a shell command:

    # Exploit starts a process inside the sandbox
    $ sandbox-exec -n no-network /bin/bash
    # Malicious process attempts to access restricted resource
    $ echo "malicious_payload" > /restricted/resource

    In this example, the exploit starts a process in the sandbox using the `sandbox-exec` command. The exploit then attempts to write a “malicious_payload” to a restricted resource. If the sandbox restrictions are functioning correctly, this operation should fail. However, due to the vulnerability, the operation succeeds, potentially leading to system compromise or data leakage.

    Recommended Mitigations

    Users are advised to immediately apply the vendor patch to address this vulnerability. In cases where immediate patching is not possible, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as temporary mitigation. However, these are not long-term solutions and can only minimize the risk of exploitation. They do not address the underlying vulnerability. Therefore, applying the vendor patch is the best course of action to completely mitigate this vulnerability.
