+
+
+### GHSA-q523-c695-h3hp - Stored HTML injection on time tracking
+
+An HTML injection vulnerability occurs in the time tracking function of OpenProject version 17.0.2. The application does not escape HTML tags, an attacker with administrator privileges can create a work package with the name containing the HTML tags and add it to the `Work package` section when creating time tracking.
+
+
+
+Responsibly disclosed by Researcher: Nguyen Truong Son ([truongson526@gmail.com](mailto:truongson526@gmail.com)) through the GitHub advisory.

+For more information, please see the [GitHub advisory #GHSA-q523-c695-h3hp](https://github.com/opf/openproject/security/advisories/GHSA-q523-c695-h3hp)
+
+
+
+### GHSA-x37c-hcg5-r5m7 - Command Injection on OpenProject repositories leads to Remote Code Execution
+
+An arbitrary file write vulnerability exists in OpenProject’s repository changes endpoint (`/projects/:project_id/repository/changes`) when rendering the “latest changes” view via `git log`.
+
+
+
+By supplying a specially crafted `rev` value (for example, `rev=--output=/tmp/poc.txt`), an attacker can inject `git log` command-line options. When OpenProject executes the SCM command, Git interprets the attacker-controlled `rev` as an option and writes the output to an attacker-chosen path.
+
+
+
+As a result, any user with the `:browse_repository` permission on the project can create or overwrite arbitrary files that the OpenProject process user is permitted to write. The written contents consist of `git log` output, but by crafting custom commits the attacker can still upload valid shell scripts, ultimately leading to RCE. The RCE lets the attacker create a reverse shell to the target host and view confidential files outside of OpenProject, such as `/etc/passwd`.
