Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: OneUptime < 10.0.21 has a critical flaw in **Synthetic Monitors**. Untrusted code execution is mishandled. π₯ **Consequences**: Leads to **Remote Code Execution (RCE)**. Total system compromise possible.
Q2Root Cause? (CWE/Flaw)
π‘οΈ **Root Cause**: **CWE-749** (Exposed Dangerous Method or Function). The vulnerability stems from improper handling of untrusted code within the Synthetic Monitors module.β¦
π **Hackers Can**: Execute arbitrary code remotely. π **Access**: Full control over the server. π **Privileges**: High impact on Confidentiality, Integrity, and Availability (CVSS H:H:H).
Q5Is exploitation threshold high? (Auth/Config)
π **Threshold**: Medium. π‘οΈ **Auth Required**: **Yes** (PR:L - Privileges Required: Low). π±οΈ **UI Interaction**: None (UI:N). β‘ **Complexity**: Low (AC:L). Attacker needs low-level access but no user interaction.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π« **Public Exploit**: **No**. The `pocs` list is empty in the data. π **Wild Exploitation**: Not currently reported. π **Status**: Advisory published, but no PoC code available yet.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Check your OneUptime version. π **Feature**: Look at **Synthetic Monitors** configuration. π οΈ **Scan**: Verify if version < 10.0.21. If yes, you are vulnerable.
Q8Is it fixed officially? (Patch/Mitigation)
β **Fixed**: **Yes**. π¦ **Patch**: Upgrade to **OneUptime 10.0.21** or later. π **Source**: Official GitHub Release & Security Advisory (GHSA-jw8q-gjvg-8w4q).
Q9What if no patch? (Workaround)
π§ **No Patch?**: Isolate the Synthetic Monitors service. π« **Restrict Access**: Limit network access to low-privilege users only. π **Disable**: Temporarily disable Synthetic Monitors if possible until patched.
Q10Is it urgent? (Priority Suggestion)
π₯ **Urgency**: **HIGH**. π **Published**: 2026-03-10. βοΈ **CVSS**: 9.8 (Critical). π **Action**: Patch immediately. RCE risk is severe even with low-privilege access.
