## What is CVE-2026-112077?

CVE-2026-112077 is a medium-severity vulnerability in radareorg radare2, published on 19 Oct 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

A vulnerability was detected in radareorg radare2 6.2.0/6.2.2. This issue affects the function r_core_cmd_str_pipe in the library libr/core/rtr_http.inc.c of the component HTTP Sandbox Policy Handler. Performing a manipulation results in protection mechanism failure. Remote exploitation of the attack is possible. The attack is considered to have high complexity. The exploitability is assessed as difficult. Upgrading to version 6.2.4 is capable of addressing this issue. The patch is named 18fd12efa98a7d1977de7bdd379d8a848777b90f. Upgrading the affected component is recommended. The pre-requisite of the vulnerability is reflected by the CVSS vector. One of the project maintainers explains: "There is a real sandbox configuration issue here, but the report overstates it. The HTTP server defaults to http.sandbox=true, so commands received through /cmd temporarily enable cfg.sandbox. However, cfg.sandbox.grain defaults to all, which means all sandbox capabilities - including exec - remain allowed. Therefore enabling the HTTP sandbox alone does NOT prevent commands from spawning processes. This only matters when the HTTP command endpoint is reachable by someone you do not trust. It is not a remote vulnerability by default: the HTTP server must first be started and exposed to the attacker."

Weakness: CWE-693 (Protection Mechanism Failure)

Affected product: radareorg radare2. 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.
