vulnerabilities as referenced in the ALAS-2023-1695 advisory.

  - Apache Batik 1.13 is vulnerable to server-side request forgery, caused by improper input validation by the

    cause the underlying server to make arbitrary GET requests. (CVE-2020-11987)

  - Server-Side Request Forgery (SSRF) vulnerability in Batik of Apache XML Graphics allows an attacker to
    load a url thru the jar protocol. This issue affects Apache XML Graphics Batik 1.14. (CVE-2022-38398)

  - Server-Side Request Forgery (SSRF) vulnerability in Batik of Apache XML Graphics allows an attacker to
    fetch external resources. This issue affects Apache XML Graphics Batik 1.14. (CVE-2022-38648)

  - Server-Side Request Forgery (SSRF) vulnerability in Batik of Apache XML Graphics allows an attacker to
    access files using a Jar url. This issue affects Apache XML Graphics Batik 1.14. (CVE-2022-40146)

  - A vulnerability in Batik of Apache XML Graphics allows an attacker to run untrusted Java code from an SVG.
    This issue affects Apache XML Graphics prior to 1.16. It is recommended to update to version 1.16.
    (CVE-2022-41704)

  - A vulnerability in Batik of Apache XML Graphics allows an attacker to run Java code from untrusted SVG via
    JavaScript. This issue affects Apache XML Graphics prior to 1.16. Users are recommended to upgrade to
    version 1.16. (CVE-2022-42890)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
