Summary

The XSS Protection API module prior to version 1.0.12 in Apache Sling employs an insecure SAX parser to validate input strings, enabling potential XXE attacks. Attackers could exploit this vulnerability to access sensitive filesystem data, conduct SSRF attacks, perform internal port scanning, or cause denial-of-service (DoS) on the impacted application. It is crucial for developers to implement secure input validation mechanisms to mitigate risks associated with this vulnerability.
