|---|---|---|---|
| npm | switcher-client | < 3.1.4 | 3.1.4 |
Details
As written in the advisory (Markdown source, shown as plain text).
### Impact
Unsanitized input flows into Strategy match operation (EXIST), where it is used to build a regular expression. This may result in a Regular expression Denial of Service attack (reDOS).
### Patches
Patched in 3.1.4
### Workarounds
Avoid using Strategy settings that use REGEX in conjunction with EXIST and NOT_EXIST operations.
