Fix code scanning alert no. 1: Regular expression injection

[litencatt]

Fixes https://github.com/litencatt/gallery-fake/security/code-scanning/1

To fix the problem, we need to sanitize the ws variable before using it to construct the regular expression. We can use the _.escapeRegExp function from the lodash library to escape any special characters in the ws variable. This will ensure that the regular expression is constructed safely without any risk of injection.

1. Install the lodash library if it is not already installed.
2. Import the _.escapeRegExp function from lodash.
3. Use _.escapeRegExp to sanitize the ws variable before using it in the regular expression.
