Description
A command injection vulnerability exists in DigitalOcean Droplet Agent through 1.3.2. The troubleshooting actioner component (internal/troubleshooting/actioner/actioner.go) processes metadata from the metadata service endpoint and executes commands specified in the TroubleshootingAgent.Requesting array without adequate input validation. While the code validates that artifacts exist in the validInvestigationArtifacts map, it fails to sanitize the actual command content after the "command:" prefix. This allows an attacker who can control metadata responses to inject and execute arbitrary OS commands with root privileges. The attack is triggered by sending a TCP packet with specific sequence numbers to the SSH port, which causes the agent to fetch metadata from http://169.254.169.254/metadata/v1.json. The vulnerability affects the command execution flow in internal/troubleshooting/actioner/actioner.go (insufficient validation), internal/troubleshooting/command/exec.go (direct exec.CommandContext call), and internal/troubleshooting/command/command.go (command parsing without sanitization). This can lead to complete system compromise, data exfiltration, privilege escalation, and potential lateral movement across cloud infrastructure.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/digitalocean/droplet-agent. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Remediation status
No patched version of github.com/digitalocean/droplet-agent has shipped for CVE-2026-24516 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2026-24516 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2026-24516. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
