Description
Command injection vulnerability in console.run_module_with_output() in pymetasploit3 through version 1.0.6 allows attackers to inject newline characters into module options such as RHOSTS. This breaks the intended command structure and causes the Metasploit console to execute additional unintended commands, potentially leading to arbitrary command execution and manipulation of Metasploit sessions.

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for pymetasploit3, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Remediation status
The records we use list no patched version of pymetasploit3 for CVE-2026-5463. Check the maintainer's advisory, and where your build allows, override or pin the dependency away from the vulnerable range.
Mitigate without a patch
Stop passing untrusted input into the interpreter or shell: call the affected binary with an argument array rather than a composed command string, reject anything outside a strict allowlist of expected values, and run the component under an account that cannot reach beyond the work it legitimately does.
