Regular Expression Denial of Service in Handlebars
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| npm | handlebars | >= 4.0.0, < 4.4.5 | 4.4.5 |
Details
As written in the advisory (Markdown source, shown as plain text).
Handlebars before 4.4.5 allows Regular Expression Denial of Service (ReDoS) because of eager matching. The parser may be forced into an endless loop while processing crafted templates. This may allow attackers to exhaust system resources.
