The readDir Endpoint Scope can be Bypassed With Symbolic Links in Tauri
Exploitation Status
Proof-of-concept exploit code exists
- CISA’s SSVC triage found public proof-of-concept exploit code for this CVE, though no confirmed active exploitation.
- CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.

How urgent is this, really
Where this sits among everything scored
Real-World Exposure
tauriReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects crates.io packages — download data is not available via public APIs for these ecosystems.
Description
Impact
Due to missing canonicalization when readDir is called recursively, it was possible to display directory listings outside of the defined fs scope. This required a crafted symbolic link or junction folder inside an allowed path of the fs scope. No arbitrary file content could be leaked.
Patches
The issue has been resolved in https://github.com/tauri-apps/tauri/pull/5123 and the implementation now properly checks if the
requested (sub) directory is a symbolic link outside of the defined scope.
Workarounds
Disable the readDir endpoint in the allowlist inside the tauri.conf.json.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for tauri, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update tauri to 1.0.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-39215 is resolved across your whole dependency graph.
Workarounds
Resolve every user-supplied path to its canonical form and reject anything that escapes the intended directory, and run the component under an account that has no read or write access outside the directory it legitimately serves.
