CVE-2026-33667

OpenProject: 2FA OTP Verification Missing Rate Limiting

OpenProject is an open-source project management application. In versions prior to 17.3.0, 2FA OTP verification in the confirm_otp action of the two_factor_authentication module has no rate limiting, lockout mechanism, or failed-attempt tracking. The existing brute_force_block_after_failed_logins setting only counts password login failures and does not apply to the 2FA verification stage, and neither the fail_login nor stage_failure methods increment any counter, lock the account, or add any delay. With the default TOTP drift window of ±60 seconds allowing approximately 5 valid codes at any time, an attacker who knows a user's password can brute-force the 6-digit TOTP code at roughly 5-10 attempts per second with an expected completion time of approximately 11 hours. The same vulnerability applies to backup code verification. This effectively allows complete 2FA bypass for any account where the password is known. This issue has been fixed in version 17.3.0.

OpenProject has Cross-Project Meeting Agenda Item Injection via Unscoped Section Lookup

OpenProject is open-source, web-based project management software. Prior to version 17.3.0, a user with `manage_agendas` permission in any project can inject agenda items into meetings belonging to any other project on the instance — even projects they have no access to. No knowledge of the target project, meeting, or victim is required; the attacker can blindly spray items into every meeting on the instance by iterating sequential section IDs. Version 17.3.0 patches the issue.

OpenProject has Improper Access Control on User Management allows user managers to lock admin accounts

OpenProject is an open-source, web-based project management software. Prior to 17.0.2, users with the Manage Users permission can lock and unlock users. This functionality should only be possible for users of the application, but they were not supposed to be able to lock application administrators. Due to a missing permission check this logic was not enforced. The problem was fixed in OpenProject 17.0.2The problem was fixed in OpenProject 17.0.2.

CVE-2026-32698

OpenProject has a SQL Injection via Custom Field Name that can be chained to Remote Code Execution

OpenProject is an open-source, web-based project management software. Versions prior to 16.6.9, 17.0.6, 17.1.3, and 17.2.1 are vulnerable to an SQL injection attack via a custom field's name. When that custom field was used in a Cost Report, the custom field's name was injected into the SQL query without proper sanitation. This allowed an attacker to execute arbitrary SQL commands during the generation of a Cost Report. As custom fields can only be generated by users with full administrator privileges, the attack surface is somewhat reduced. Together with another bug in the Repositories_module, that used the project identifier without sanitation to generate the checkout path for a git repository in the filesystem, this allowed an attacker to checkout a git repository to an arbitrarily chosen path on the server. If the checkout is done within certain paths within the OpenProject application, upon the next restart of the application, this allows the attacker to inject ruby code into the application. As the project identifier cannot be manually edited to any string containing special characters like dots or slashes, this needs to be changed via the SQL injection described above. Versions 16.6.9, 17.0.6, 17.1.3, and 17.2.1 fix the issue.

CVE-2026-32703

OpenProject's repository files are served with the MIME type allowing them to be used to bypass Content Security Policy

OpenProject is an open-source, web-based project management software. In versions prior to 16.6.9, 17.0.6, 17.1.3, and 17.2.1, the Repositories module did not properly escape filenames displayed from repositories. This allowed an attacker with push access into the repository to create commits with filenames that included HTML code that was injected in the page without proper sanitation. This allowed a persisted XSS attack against all members of this project that accessed the repositories page to display a changeset where the maliciously crafted file was deleted. Versions 16.6.9, 17.0.6, 17.1.3, and 17.2.1 fix the issue.

CVE-2026-31974

Blind SSRF on OpenProject instance via webhooks

OpenProject is an open-source, web-based project management software. Prior to 17.2.0, OpenProject SMTP test endpoint (POST /admin/settings/mail_notifications) accepts arbitrary host and port values and exhibits measurable differences in response behaviour depending on whether the target IP exists and whether the port is open. An attacker with access can use these timing and error distinctions to map internal hosts and identify which services/ports are reachable. Similarly, you can create webhooks in OpenProject and point them to arbitrary IPs, resulting in the same kind of SSRF issue which allows attackers to scan the internal network. This vulnerability is fixed in 17.2.0.

CVE-2026-30236

OpenProject users that are not project members can be used to calculate Labor Budget, leaking their global hourly rate

OpenProject is an open-source, web-based project management software. Prior to 17.2.0, when editing a project budget and planning the labor cost, it was not checked that the user that was planned in the budget is actually a project member. This exposed the user's default rate (if one was set up) to users that should only see that information for project members. Also, the endpoint that handles the pre-calculation for the frontend to display a preview of the costs, while it was being entered, did not properly validate the membership of the user as well. This also allowed to calculate costs with the default rate of non-members. This vulnerability is fixed in 17.2.0.

OpenProject BIM BCF XML Import: <Snapshot> Path Traversal Leads to Arbitrary Local File Read (AFR)

OpenProject is an open-source, web-based project management software. Prior to 17.2.0, an authenticated project member with BCF import permissions can upload a crafted .bcf archive where the <Snapshot> value in markup.bcf is manipulated to contain an absolute or traversal local path (for example: /etc/passwd or ../../../../etc/passwd). During import, this untrusted <Snapshot> value is used as file.path during attachment processing. As a result, local filesystem content can be read outside the intended ZIP scope. This results in an Arbitrary File Read (AFR) within the read permissions of the OpenProject application user. This vulnerability is fixed in 17.2.0.

Business Logic Error on OpenProject through hyperlinks in markdown using DOM clobbering

OpenProject is an open-source, web-based project management software. Prior to 17.2.0, this vulnerability occurs due to improper validation of OpenProject’s Markdown rendering, specifically in the hyperlink handling. This allows an attacker to inject malicious hyperlink payloads that perform DOM clobbering. DOM clobbering can crash or blank the entire page by overwriting native DOM functions with HTML elements, causing critical JavaScript calls to throw runtime errors during application initialization and halt further execution. This vulnerability is fixed in 17.2.0.

OpenProject has a Permission Check bypass on Budget deletion allows reassignment of WorkPackages into other budgets

OpenProject is an open-source, web-based project management software. Prior to 17.2.0, when budgets are deleted, the work packages that were assigned to this budget need to be moved to a different budget. This action was performed before the permission check on the delete action was executed. This allowed all users in the application to delete work package budget assignments. This vulnerability is fixed in 17.2.0.
