## What is CVE-2025-15545?

CVE-2025-15545 is a high-severity command injection vulnerability in TP-Link Systems Inc. Archer RE605X, published on 29 Jan 2026. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

The backup restore function does not properly validate unexpected or unrecognized tags within the backup file. When such a crafted file is restored, the injected tag is interpreted by a shell, allowing execution of arbitrary commands with root privileges. Successful exploitation allows the attacker to gain root-level command execution, compromising confidentiality, integrity and availability.

Weakness: CWE-20 (Improper Input Validation)

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.
