Lifecycle Timeline
2DescriptionGitHub Advisory
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.
AnalysisAI
OpenProject versions prior to 17.2.0 allow authenticated users with BCF import permissions to read arbitrary files from the server through path traversal in crafted .bcf archive uploads. An attacker can manipulate the Snapshot field in markup.bcf to reference absolute or traversal paths (such as /etc/passwd), enabling unauthorized file disclosure within the application's read permissions. This vulnerability requires valid project member credentials and no patch is currently available.

RemediationAI
Fixed in version 17.2.0.. Validate and sanitize file path inputs. Use allowlists. Restrict network access to the affected service where possible.
