CVE-2023-33960

OpenProject is web-based project management software. For any OpenProject installation, a `robots.txt` file is generated

OpenProject is web-based project management software. For any OpenProject installation, a robots.txt file is generated through the server to denote which routes shall or shall not be accessed by crawlers. These routes contain project identifiers of all public projects in the instance.

Prior to version 12.5.6, even if the entire instance is marked as Login required and prevents all truly anonymous access, the /robots.txt route remains publicly available. Version 12.5.6 has a fix for this issue. Alternatively, users can download a patchfile to apply the patch to any OpenProject version greater than 10.0 As a workaround, one may mark any public project as non-public and give anyone in need of access to the project a membership.

SSVC asks the questions that actually drive patch urgency: is it being exploited, can attacks be automated, and how total is the impact.
