GHSA-457R-CQC8-9VJ9
Vulnerability from github – Published: 2022-11-23 15:39 – Updated: 2025-08-25 17:22sweetalert2 versions 10.16.10 and up until 11.0.0 are vulnerable to hidden functionality that was introduced by the maintainer. The package outputs audio and/or video messages that do not pertain to the functionality of the package and is not included in versions 10.0.0 - 10.16.9.
Workaround
Use a version 10.0.0 - 10.16.9 of the package until the maintainer releases a fix.

Mitigation
Always verify the integrity of the product that is being installed.
CAPEC-133: Try All Common Switches
An attacker attempts to invoke all common switches and options in the target application for the purpose of discovering weaknesses in the target. For example, in some applications, adding a --debug switch causes debugging information to be displayed, which can sometimes reveal sensitive processing or configuration information to an attacker. This attack differs from other forms of API abuse in that the attacker is indiscriminately attempting to invoke options in the hope that one of them will work rather than specifically targeting a known option. Nonetheless, even if the attacker is familiar with the published options of a targeted application this attack method may still be fruitful as it might discover unpublicized functionality.
CAPEC-190: Reverse Engineer an Executable to Expose Assumed Hidden Functionality
An attacker analyzes a binary file or executable for the purpose of discovering the structure, function, and possibly source-code of the file by using a variety of analysis techniques to effectively determine how the software functions and operates. This type of analysis is also referred to as Reverse Code Engineering, as techniques exist for extracting source code from an executable. Several techniques are often employed for this purpose, both black box and white box. The use of computer bus analyzers and packet sniffers allows the binary to be studied at a level of interactions with its computing environment, such as a host OS, inter-process communication, and/or network communication. This type of analysis falls into the 'black box' category because it involves behavioral analysis of the software without reference to source code, object code, or protocol specifications.
