Document Picker: Path Traversal: '/dir/../filename'
CVE-2024-25466 is a high-severity path traversal: '/dir/../filename' vulnerability in Document Picker from React-native-documents, with a CVSS 3.1 base score of 7.8 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. The record lists version 9.1.1 as the first without the flaw, so updating Document Picker to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.54% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Document Picker to 9.1.1 or a later version.

Official description
Directory Traversal vulnerability in React Native Document Picker before v.9.1.1 and fixed in v.9.1.1 allows a local attacker to execute arbitrary code via a crafted script to the Android library component.
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
The underlying weakness: Path Traversal: '/dir/../filename'
The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize /dir/../filename sequences that can resolve to a location that is outside of that directory.
How developers prevent this class of flaw
- Inputs should be decoded and canonicalized to the application's current internal representation before being validated (CWE-180). Make sure that the application does not decode the same input twice (CWE-174). Such errors could be used to bypass allowlist validation schemes by introducing dangerous inputs after they have been checked.
