## What is CVE-2026-48098?

CVE-2026-48098 is a high-severity command injection vulnerability in 0x5t4l1n NexTOR_IP_CHANGER, published on 7 Aug 2026. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

NexTor IP Changer is a command-line tool that leverages the Tor network to periodically rotate a user's IP address. Versions prior to 2.0.0 execute privileged system commands using `sudo` and `shell=True` directly inside application logic. In environments where passwordless sudo (`NOPASSWD`) is enabled, privileged commands may execute silently without explicit user confirmation. Version 2.0.0 fixes the issue.

Weakness: CWE-78 (Improper Neutralization of Special Elements used in an OS Command), CWE-250 (Execution with Unnecessary Privileges)

Affected product: 0x5t4l1n NexTOR_IP_CHANGER. 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.
