Description
Zend_Feed_Rss and Zend_Feed_Atom were found to contain potential XML eXternal Entity (XXE) vectors due to insecure usage of PHP's DOM extension. External entities could be specified by adding a specific DOCTYPE element to feeds; exploiting this vulnerability could coerce opening arbitrary files and/or TCP connections.
A similar issue was fixed for 1.11.13 and 1.12.0, in the Zend_Feed::import() factory method; however, the reporter of the issue discovered that the individual classes contained similar functionality in their constructors which remained vulnerable.
Affected versions
Packagist
| Package | Vulnerable | Fixed in |
|---|---|---|
| zendframework/zendframework1 | >= 1.11.0, < 1.11.15 |
1.11.15 |
| zendframework/zendframework1 | >= 1.12.0, < 1.12.1 |
1.12.1 |
How to fix
Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.

Weakness
CWE-611: Improper Restriction of XML External Entity Reference
The product processes an XML document that can contain XML entities with URIs that resolve to documents outside of the intended sphere of control, causing the product to embed incorrect documents into its output.
How to prevent it
- Implementation, System Configuration: Many XML parsers and validators can be configured to disable external entity expansion.
