## What is CVE-2026-63722?

CVE-2026-63722 is a high-severity command injection vulnerability in ICEcoder, published on 19 Aug 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

ICEcoder 8.1 contains an unauthenticated remote code execution vulnerability that allows unauthenticated attackers to execute arbitrary OS commands by chaining an authentication bypass, CSRF validation bypass, and unsanitized command execution. Attackers can send a single HTTP POST request to the terminal endpoint with a password parameter to bypass authentication, a non-empty csrf parameter to skip CSRF validation, and an arbitrary command string passed directly to proc_open() to achieve remote code execution as the web-server user.

Weakness: CWE-306 (Missing Authentication for Critical Functionality)

Check this codebase for CVE-2026-63722 and fix it if it is affected.

What it is: CVE-2026-63722 is a high-severity command injection vulnerability in ICEcoder, published on 19 Aug 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-63722 exists.

Affected product: ICEcoder. 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.
