The following code is flagged as dead (since it's *replacing* rather than updating the existing Object):
https://github.com/mozilla/pdf.js/blob/4483cba72410027acf46630ebf252ae529704476/src/core/xfa/template.js#L2336-L2339
according to the alert in https://github.com/mozilla/pdf.js/security/code-scanning/103?query=ref%3Arefs%2Fheads%2Fmaster

Looking at the surrounding code, I can see a couple of possibilities here:
 1. This is indeed just dead code, which should be removed.
 2. The code should be moved up, and placed just *above* the previous block instead.
 3. There should be other, more invasive, changes made to this code...

/cc @calixteman Which solution is correct here?
Assuming it's either option 1 or 2, I can submit a patch to fix this.
this.wordCharacterCount = getInteger({
      data: attributes.wordCharacterCount,
      defaultValue: 7,
      validate: x => x >= 0,
    });
  }
}
class Image extends StringObject {
  constructor(attributes) {
    super(TEMPLATE_NS_ID, "image");
    this.aspect = getStringOption(attributes.aspect, [
      "fit",
      "actual",
      "height",
      "none",
      "width",
    ]);
    this.contentType = attributes.contentType || "";
    this.href = attributes.href || "";
    this.id = attributes.id || "";
    this.name = attributes.name || "";
    this.transferEncoding = getStringOption(attributes.transferEncoding, [
      "base64",
      "none",
      "package",
    ]);
    this.use = attributes.use || "";
    this.usehref = attributes.usehref || "";
  }
