## What is CVE-2025-26326?

CVE-2025-26326 is a high-severity authentication bypass vulnerability in n/a, published on 28 Feb 2025. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

### Official description

A vulnerability was identified in the NVDA Remote (version 2.6.4) and Tele NVDA Remote (version 2025.3.3) remote connection add-ons, which allows an attacker to obtain total control of the remote system by guessing a weak password. The problem occurs because these add-ons accept any password entered by the user and do not have an additional authentication or computer verification mechanism. Tests indicate that more than 1,000 systems use easy-to-guess passwords, many with less than 4 to 6 characters, including common sequences. This allows brute force attacks or trial-and-error attempts by malicious invaders. The vulnerability can be exploited by a remote attacker who knows or can guess the password used in the connection. As a result, the attacker gains complete access to the affected system and can execute commands, modify files, and compromise user security.

Weakness: CWE-287 (Improper Authentication)

Check this codebase for CVE-2025-26326 and fix it if it is affected.

What it is: CVE-2025-26326 is a high-severity authentication bypass vulnerability in n/a, published on 28 Feb 2025. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2025-26326 in the wild and no public exploit code.

Affected product: n/a. 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.
