Debusine
Monthly
Arbitrary symlink creation in Debusine's mergeuploads task allows remote unauthenticated attackers to overwrite files accessible to the worker process. Affected versions 0.12.0 through 0.14.8 fail to sanitize fully user-controlled paths embedded in Debian manifest files (.dsc and .changes), enabling path traversal via CWE-59 link-following. Despite a CVSS network-accessible, no-auth vector, real-world risk is bounded by deployment context - exploitation requires the ability to submit packages to a Debusine instance. No public exploit identified at time of analysis and EPSS sits at 0.02% (4th percentile).
Missing authorization controls on Debusine's artifact relationship endpoints allow remote actors to create and delete artifact relationships without holding the necessary write permissions, affecting all versions from 0.2.0 through 0.14.5. The only implicit gatekeeping was visibility of the referenced artifacts - not modification rights - a CWE-862 (Missing Authorization) flaw that exposes both data integrity and limited confidentiality of build artifact metadata. No public exploit code exists and EPSS places exploitation probability at 0.01% (3rd percentile), reflecting the tool's niche deployment scope within Debian build infrastructure; the vulnerability is not confirmed actively exploited (CISA KEV).
