CVE-2026-49248 WRITEUP HIGH WRITEUP
OneDev <= 15.0.6 - Authenticated Arbitrary File Overwrite via TarUtils.untar
OneDev is a Git server with CI/CD, kanban, and packages. In versions 15.0.6 and below, TarUtils.untar() creates symbolic links verbatim from TAR entry getLinkName() without validating whether the target is an absolute path. A subsequent file entry in the same archive traverses the symlink, writing to arbitrary server-side locations. This is exploitable by any authenticated user with CI Job write access — no admin interaction required. This is an incomplete fix bypass of CVE-2021-21251 (GHSA-2w6j-wc8c-9mq2): that patch blocked .. path segments but did not address absolute symlink targets. This issue has been fixed in version 15.0.7.
CVE-2024-45309 WRITEUP HIGH WRITEUP
OneDev Unauthenticated Arbitrary File Read
OneDev is a Git server with CI/CD, kanban, and packages. A vulnerability in versions prior to 11.0.9 allows unauthenticated users to read arbitrary files accessible by the OneDev server process. This issue has been fixed in version 11.0.9.

CVE-2021-21242 WRITEUP CRITICAL WRITEUP
OneDev < 4.0.3 - Unauthenticated Remote Code Execution via Attachment-Support Header Deserialization
OneDev is an all-in-one devops platform. In OneDev before version 4.0.3, there is a critical vulnerability which can lead to pre-auth remote code execution. AttachmentUploadServlet deserializes untrusted data from the `Attachment-Support` header. This Servlet does not enforce any authentication or authorization checks. This issue may lead to pre-auth remote code execution. This issue was fixed in 4.0.3 by removing AttachmentUploadServlet and not using deserialization

OneDev <4.0.3 - Pre-Auth Code Injection
OneDev is an all-in-one devops platform. In OneDev before version 4.0.3, a Kubernetes REST endpoint exposes two methods that deserialize untrusted data from the request body. These endpoints do not enforce any authentication or authorization checks. This issue may lead to pre-auth RCE. This issue was fixed in 4.0.3 by not using deserialization at KubernetesResource side.

CVE-2021-21245 WRITEUP CRITICAL WRITEUP
OneDev < 4.0.3 - Arbitrary File Upload via AttachmentUploadServlet
OneDev is an all-in-one devops platform. In OneDev before version 4.0.3, AttachmentUploadServlet also saves user controlled data (`request.getInputStream()`) to a user specified location (`request.getHeader("File-Name")`). This issue may lead to arbitrary file upload which can be used to upload a WebShell to OneDev server. This issue is addressed in 4.0.3 by only allowing uploaded file to be in attachments folder. The webshell issue is not possible as OneDev never executes files in attachments folder.

CVE-2021-21246 WRITEUP HIGH WRITEUP
OneDev < 4.0.3 - Unauthenticated Sensitive Data Leak via UserResource Endpoint
OneDev is an all-in-one devops platform. In OneDev before version 4.0.3, the REST UserResource endpoint performs a security check to make sure that only administrators can list user details. However for the `/users/{id}` endpoint there are no security checks enforced so it is possible to retrieve arbitrary user details including their Access Tokens! These access tokens can be used to access the API or clone code in the build spec via the HTTP(S) protocol. It has permissions to all projects accessible by the user account. This issue may lead to `Sensitive data leak` and leak the Access Token which can be used to impersonate the administrator or any other users. This issue was addressed in 4.0.3 by removing user info from restful api.

CVE-2021-21248 WRITEUP CRITICAL WRITEUP
OneDev < 4.0.3 - Remote Code Execution via Build Endpoint Parameter Injection
OneDev is an all-in-one devops platform. In OneDev before version 4.0.3, there is a critical vulnerability involving the build endpoint parameters. InputSpec is used to define parameters of a Build spec. It does so by using dynamically generated Groovy classes. A user able to control job parameters can run arbitrary code on OneDev's server by injecting arbitrary Groovy code. The ultimate result is in the injection of a static constructor that will run arbitrary code. For a full example refer to the referenced GHSA. This issue was addressed in 4.0.3 by escaping special characters such as quote from user input.

CVE-2021-32651 WRITEUP LOW WRITEUP
OneDev <4.4.1 - Blind LDAP Injection
OneDev is a development operations platform. If the LDAP external authentication mechanism is enabled in OneDev versions 4.4.1 and prior, an attacker can manipulate a user search filter to send forged queries to the application and explore the LDAP tree using Blind LDAP Injection techniques. The specific payload depends on how the User Search Filter property is configured in OneDev. This issue was fixed in version 4.4.2.

CVE-2022-38301 WRITEUP HIGH WRITEUP
Onedev v7.4.14 - Path Traversal via Crafted JAR File Upload
Onedev v7.4.14 contains a path traversal vulnerability which allows attackers to access restricted files and directories via uploading a crafted JAR file into the directory /opt/onedev/lib.

CVE-2022-39205 WRITEUP CRITICAL WRITEUP
OneDev < 7.3.0 - Unauthenticated Remote Code Execution via Git Pre-Receive Callback Endpoint
Onedev is an open source, self-hosted Git Server with CI/CD and Kanban. In versions of Onedev prior to 7.3.0 unauthenticated users can take over a OneDev instance if there is no properly configured reverse proxy. The /git-prereceive-callback endpoint is used by the pre-receive git hook on the server to check for branch protections during a push event. It is only intended to be accessed from localhost, but the check relies on the X-Forwarded-For header. Invoking this endpoint leads to the execution of one of various git commands. The environment variables of this command execution can be controlled via query parameters. This allows attackers to write to arbitrary files, which can in turn lead to the execution of arbitrary code. Such an attack would be very hard to detect, which increases the potential impact even more. Users are advised to upgrade. There are no known workarounds for this issue.

CVE-2022-39206 WRITEUP CRITICAL WRITEUP
OneDev < 7.3.0 - Authenticated Remote Code Execution via Docker Socket Mount
Onedev is an open source, self-hosted Git Server with CI/CD and Kanban. When using Docker-based job executors, the Docker socket (e.g. /var/run/docker.sock on Linux) is mounted into each Docker step. Users that can define and trigger CI/CD jobs on a project could use this to control the Docker daemon on the host machine. This is a known dangerous pattern, as it can be used to break out of Docker containers and, in most cases, gain root privileges on the host system. This issue allows regular (non-admin) users to potentially take over the build infrastructure of a OneDev instance. Attackers need to have an account (or be able to register one) and need permission to create a project. Since code.onedev.io has the right preconditions for this to be exploited by remote attackers, it could have been used to hijack builds of OneDev itself, e.g. by injecting malware into the docker images that are built and pushed to Docker Hub. The impact is increased by this as described before. Users are advised to upgrade to 7.3.0 or higher. There are no known workarounds for this issue.

CVE-2022-39207 WRITEUP MEDIUM WRITEUP
OneDev < 7.3.0 - Stored Cross-Site Scripting via Build Artifact HTML Rendering
Onedev is an open source, self-hosted Git Server with CI/CD and Kanban. During CI/CD builds, it is possible to save build artifacts for later retrieval. They can be accessed through OneDev's web UI after the successful run of a build. These artifact files are served by the webserver in the same context as the UI without any further restrictions. This leads to Cross-Site Scripting (XSS) when a user creates a build artifact that contains HTML. When accessing the artifact, the content is rendered by the browser, including any JavaScript that it contains. Since all cookies (except for the rememberMe one) do not set the HttpOnly flag, an attacker could steal the session of a victim and use it to impersonate them. To exploit this issue, attackers need to be able to modify the content of artifacts, which usually means they need to be able to modify a project's build spec. The exploitation requires the victim to click on an attacker's link. It can be used to elevate privileges by targeting admins of a OneDev instance. In the worst case, this can lead to arbitrary code execution on the server, because admins can create Server Shell Executors and use them to run any command on the server. This issue has been patched in version 7.3.0. Users are advised to upgrade. There are no known workarounds for this issue.

CVE-2022-39208 WRITEUP HIGH WRITEUP
OneDev < 7.3.0 - Unauthenticated Arbitrary File Read via Project Directory Exposure
Onedev is an open source, self-hosted Git Server with CI/CD and Kanban. All files in the /opt/onedev/sites/ directory are exposed and can be read by unauthenticated users. This directory contains all projects, including their bare git repos and build artifacts. This file disclosure vulnerability can be used by unauthenticated attackers to leak all project files of any project. Since project IDs are incremental, an attacker could iterate through them and leak all project data. This issue has been resolved in version 7.3.0 and users are advised to upgrade. There are no known workarounds for this issue.

CVE-2023-24828 WRITEUP HIGH WRITEUP
Onedev <7.9.12 - Privilege Escalation
Onedev is a self-hosted Git Server with CI/CD and Kanban. In versions prior to 7.9.12 the algorithm used to generate access token and password reset keys was not cryptographically secure. Existing normal users (or everyone if it allows self-registration) may exploit this to elevate privilege to obtain administrator permission. This issue is has been addressed in version 7.9.12. Users are advised to upgrade. There are no known workarounds for this vulnerability.
