Vulnerability from github – Published: 2019-02-18 23:39 – Updated: 2023-09-13 23:00

Summary

Cross-Site Scripting in backbone

Details

Affected versions of backbone are vulnerable to cross-site scripting when users are allowed to supply input to the Model#Escape function, and the output is then written to the DOM.

The vulnerability occurs as a result of the regular expression used to encode metacharacters failing to take HTML Entities such as < into account.

Recommendation

Update to version 0.5.0 or later.

Severity ?

5.4 (Medium)

Vulnerability from cvelistv5 – Published: 2018-05-31 20:00 – Updated: 2024-09-17 04:14

Summary

backbone is a module that adds in structure to a JavaScript heavy application through key-value pairs and custom events connecting to your RESTful API through JSON There exists a potential Cross Site Scripting vulnerability in the `Model#Escape` function of backbone 0.3.3 and earlier, if a user is able to supply input. This is due to the regex that's replacing things to miss the conversion of things such as `<` to `<`.

Severity ?
