Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| Go | github.com/antchfx/xpath | < 1.3.6 | 1.3.6 |
Details
As written in the advisory (Markdown source, shown as plain text).
Boolean expressions that evaluate to true can cause an infinite loop in logicalQuery.Select, leading to 100% CPU usage. This can be triggered by top-level selectors such as "1=1" or "true()".
