| Package | Affected versions | Patched versions |
|---|---|---|
| parse-server | = 9.6.0≥ 9.0.0, < 9.6.0< 8.6.47 | 9.6.08.6.47 |
| parse-server | ≥ 9.0.0, < 9.6.0-alpha.24< 8.6.47 | 9.6.0-alpha.248.6.47 |
Remote clients can crash the Parse Server process by calling a cloud function endpoint with a crafted function name that traverses the JavaScript prototype chain of a registered cloud function handler, causing a stack overflow.
The fix restricts property lookups during cloud function name resolution to own properties only, preventing prototype chain traversal from stored function handlers.
There is no known workaround.
