OneUptime Vulnerable to a Privilege Escalation via Local Storage Key Manipulation
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.
- A successful exploit gives an attacker total control of the affected component, not partial access.

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-2024-29194 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 379,145 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.
Real-World Exposure
How broadly this vulnerability is actually deployed: weekly install volume shows current usage, and reverse-dependency count shows how many other packages break if it stays unpatched.
@oneuptime/modelnpm@oneuptime/common-servernpmDescription
Summary
A security vulnerability exists in oneuptime's local storage handling, where a regular user can escalate privileges by modifying the is_master_admin key to true. This allows unauthorized access to administrative functionalities.
Details
The vulnerability lies in the improper validation of client-side stored data within the web application. Specifically, the is_master_admin key, stored in the local storage of the browser, can be manipulated by an attacker. By changing this key from false to true, the application grants administrative privileges to the user, without proper server-side validation.
POC
(I am using Firefox Developer to demonstrate this vulnerability)
Log in as a normal user. Open developer tools (hit F12), click Storage, then Local Storage. Modify the is_master_admin key from false to true.
Impact
This vulnerability represents a high security risk as it allows any authenticated user to gain administrative privileges through client-side manipulation. Most of the admin previlages were disabled except the user list. Where an attacker could see all the list of users who signed up to OneUptome.
Patch
This has been patched in 7.0.1815

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for @oneuptime/model, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update @oneuptime/model to 7.0.1815 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-29194 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-2024-29194 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2024-29194. 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-2024-29194 in your dependencies?
O3 Security finds CVE-2024-29194 across npm dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
