AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N

Name of the Vulnerable Software and Affected Versions Pretty Links plugin for WordPress versions up to, and including, 2.1.9

Description The issue arises from insufficient input sanitization and output escaping in the track link function, allowing unauthenticated attackers to inject arbitrary web scripts in pages via various IP headers and the referer header. This enables the execution of injected scripts whenever a user accesses an injected page.

Recommendations For versions up to, and including, 2.1.9, update to a version higher than 2.1.9 to resolve the issue. As a temporary workaround, consider disabling the track link function until a patch is available.
