The insufficient input sanitization and output escaping mechanisms make it possible for attackers to inject arbitrary web scripts. When a user accesses a page with this injected script, it will execute, potentially leading to malicious activities. Recognizing the risk, Lana Codes, the researcher who discovered this vulnerability, highlighted the importance of updating to the patched version to mitigate potential breaches.
Advice for Users:
- Immediate Action: Update to version 7.1.3 immediately to secure your WordPress installations.
