Unsanitized bundle*\n\nAs a result, it is possible to break the HTML context and achieve Stored XSS.\n\n## Vulnerability reproduction\n\nTo reproduce the vulnerability, follow the steps described below.\n\n•\tUnzip the IPA file of any iOS application.\n*Listing 1. Unzipping the file*\n```\nunzip test.ipa\n```\n•\tModify the value of `<key>CFBundleIdentifier</key>` by adding restricted characters in the `Info.plist` file.\n\n<img width=\"560\" alt=\"image-1\" src=\"https://github.com/user-attachments/assets/3eedf216-45ab-4d73-9815-6b02827d36d4\" />\n\n*Figure 2. Example of the modified Bundle Identifier*\n\n•\tZip the modified IPA file.\n\n*Listing 2. Zipping the file*\n```\nzip -r xss.ipa Payload/\n```\n•\tUpload the modified IPA file to your virtual device using the Correlium platform.\n \n<img width=\"762\" alt=\"image-2\" src=\"https://github.com/user-attachments/assets/7f3e8b0d-d1f9-4d86-b63b-9b3f9e8f1d0c\" />\n\n*Figure 3. Example of the uploaded malicious application*\n\n•\tOpen the XSS functionality and hover the mouse over the Uninstall button of the malicious app.\n\n<img width=\"764\" alt=\"image-3\" src=\"https://github.com/user-attachments/assets/fd621574-f2c1-42be-b30a-e8e7445c6b13\" />\n\n*Figure 4.
