CVE-2016-15026: 3breadt dd-plist xml external entity reference

A vulnerability was found in 3breadt dd-plist 1.17 and classified as problematic. Affected by this issue is some unknown functionality. The manipulation leads to xml external entity reference. An attack has to be approached locally. Upgrading to version 1.18 is able to address this issue. The patch is identified as 8c954e8d9f6f6863729e50105a8abf3f87fff74c. It is recommended to upgrade the affected component. VDB-221486 is the identifier assigned to this vulnerability.

Security readout for executives and security teams

Plain-English summary

CVE-2016-15026 affects the 3breadt dd-plist library version 1.17. A local, authenticated user could trigger XML external entity handling, which can expose or affect local data depending on how the component is used. The published fix is dd-plist 1.18.

Executive priority

Prioritize remediation during normal dependency maintenance, faster where dd-plist handles sensitive local data. This is not currently evidenced as internet-exploited or KEV-listed, but the fix is available and straightforward.

Technical view

The issue is classified as CWE-611, XML External Entity Reference, in 3breadt dd-plist 1.17. The CVSS 3.1 vector is AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L. Sources do not name the exact vulnerable function. The referenced patch is commit 8c954e8d9f6f6863729e50105a8abf3f87fff74c and release 1.18.

Likely exposure

Exposure is likely limited to environments that include dd-plist 1.17 and allow local users or local workflows to process plist XML through it. The source bundle does not identify downstream products.

Exploitation context

The source bundle says the attack is local and requires low privileges. CISA KEV status is false, and no provided source claims active exploitation. Treat this as dependency hygiene unless dd-plist processes sensitive local files or untrusted plist XML.

Researcher notes

Evidence is incomplete on the exact affected functionality. The key research angle is confirming whether dd-plist 1.17 permits XXE behavior in reachable local parsing paths and whether applications pass attacker-controlled plist XML to the library.

Mitigation direction

  • Upgrade dd-plist from 1.17 to 1.18 or later.
  • Verify the fixed release includes commit 8c954e8d9f6f6863729e50105a8abf3f87fff74c.
  • Check project or vendor guidance if upgrade is blocked.
  • Avoid processing untrusted plist XML with version 1.17 until remediated.

Validation and detection

  • Search SBOMs, lockfiles, and package manifests for dd-plist 1.17.
  • Confirm deployed artifacts use dd-plist 1.18 or later.
  • Identify local workflows that parse plist XML through this library.
  • Record whether affected systems process sensitive local files.
