OliveTin: RestartAction always runs actions as guest
Exploitation Status
Proof-of-concept exploit code exists
- CISA’s SSVC triage found public proof-of-concept exploit code for this CVE, though no confirmed active exploitation.
- CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.

EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
How urgent is this, really
CVE-2026-30225 plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 377,333 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.

Description
OliveTin gives access to predefined shell commands from a web interface. Prior to version 3000.11.1, an authentication context confusion vulnerability in RestartAction allows a low‑privileged authenticated user to execute actions they are not permitted to run. RestartAction constructs a new internal connect.Request without preserving the original caller’s authentication headers or cookies. When this synthetic request is passed to StartAction, the authentication resolver falls back to the guest user. If the guest account has broader permissions than the authenticated caller, this results in privilege escalation and unauthorized command execution. This vulnerability allows a low‑privileged authenticated user to bypass ACL restrictions and execute arbitrary configured shell actions. This issue has been patched in version 3000.11.1.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/OliveTin/OliveTin, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update github.com/OliveTin/OliveTin to 0.0.0-20260305000458-cb46a597b246 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-30225 is resolved across your whole dependency graph.
Workarounds
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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2026-30225 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2026-30225. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2026-30225 in your dependencies?
O3 Security finds CVE-2026-30225 across Go dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
