Top issues

Description	Example fixes
Calling map on a non-array object expression will not work. Occurrences: structure.service.ts:91	🔧 Example fixes
Unsanitized input from a function parameter flows into a member access and is used to access a property of a field assignment by name. This may allow a malicious user to access methods (e.g. toString) as opposed to regular properties of objects and cause a crash, remote code execution or more serious problems. This is known as a Prototype Pollution vulnerability. Occurrences: ghspa.js:39	🔧 Example fixes
Type declaration of 'any' loses type-safety. Consider replacing it with a more precise type. Occurrences: methods-block.component.ts:48 methods-block.component.ts:51 app.options.ts:8	🔧 Example fixes
