melange allows users to build apk packages using declarative pipelines. In version 0.11.3 to before 0.40.3, an attacker who can influence the tar stream from a QEMU guest VM could write files outside the intended workspace directory on the host. The retrieveWorkspace function extracts tar entries without validating that paths stay within the workspace, allowing path traversal via ../ sequences. This issue has been patched in version 0.40.3.

Read the publisher's advisoryAn attacker who can influence the tar stream from a QEMU guest VM could write files outside the intended workspace directory on the host. The `retrieveWorkspace` function extracts tar entries without validating that paths stay within the workspace, allowing Path Traversal via `../` sequences. **Fix:** Fixed in [6e243d0d](https://github.com/chainguard-dev/melange/commit/6e243d0d46699f837d7c392397a694d2bcc7612b). Merged in release. **Acknowledgements** melange thanks Oleh Konko from [1seal](https://1seal.org/) for discovering and reporting this issue.

Read the publisher's advisoryCISA KEV lists vulnerabilities known to be exploited. FIRST EPSS estimates the likelihood of exploitation in the next 30 days. An unavailable score does not mean zero risk.
This view includes predictions for CVE identifiers explicitly listed in public NuGet advisories. Microsoft release pages have their own prediction coverage. Check source status for the scope and latest checks.
No exploitation or prediction data is available here for these CVEs. This does not mean they are safe or unlikely to be exploited.
Compare earlier KEV listings and daily EPSS scores. Advisory wording and affected versions have a separate history.
A prediction change is reported when EPSS rises from below 10% to 10% or higher. Other daily score changes remain in this history.
See how the publisher's advisory changed over time. Each link opens the version saved at that time. The publisher's update date can differ from the date shown here.
Each link identifies one complete publisher record. History can include advisories that previously shared an identifier; an identifier removed by a publisher no longer establishes a current relationship. A historical link shows only that record and earlier saved versions. Failed checks and unchanged reads do not create new versions.
