## What is CVE-2022-39349?

CVE-2022-39349 is a medium-severity path traversal vulnerability in tasks, published on 25 Oct 2022. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

The Tasks.org Android app is an open-source app for to-do lists and reminders. The Tasks.org app uses the activity `ShareLinkActivity.kt` to handle "share" intents coming from other components in the same device and convert them to tasks. Those intents may contain arbitrary file paths as attachments, in which case the files pointed by those paths are copied in the app's external storage directory. Prior to versions 12.7.1 and 13.0.1, those paths were not validated, allowing a malicious or compromised application in the same device to force Tasks.org to copy files from its internal storage to its external storage directory, where they became accessible to any component with permission to read the external storage. This vulnerability can lead to sensitive information disclosure. All information in the user's notes and the app's preferences, including the encrypted credentials of CalDav integrations if enabled, could be accessed by third party applications installed on the same device. This issue was fixed in versions 12.7.1 and 13.0.1. There are no known workarounds.

Weakness: CWE-668 (Exposure of Resource to Wrong Sphere), CWE-441 (Unintended Proxy or Intermediary)

Check this codebase for CVE-2022-39349 and fix it if it is affected.

What it is: CVE-2022-39349 is a medium-severity path traversal vulnerability in tasks, published on 25 Oct 2022. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2022-39349 in the wild and no public exploit code.

Affected product: tasks. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
