Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Logic flaw in Clerk JS SDKs (v4.7.0 - 4.29.3). π **Consequences**: Attackers can escalate privileges, bypassing intended access controls in Auth/GetAuth functions.
π₯ **Affected**: Official Clerk JavaScript SDKs. π¦ **Versions**: 4.7.0 up to (but not including) 4.29.3. π’ **Vendor**: Clerk.
Q4What can hackers do? (Privileges/Data)
π **Hackers' Power**: Privilege Escalation. π **Impact**: Gain unauthorized access to protected resources or user data by exploiting the logic gap.
Q5Is exploitation threshold high? (Auth/Config)
π **Threshold**: High Complexity (AC:H). π« **Auth**: No Privileges Required (PR:N). π±οΈ **UI**: No User Interaction (UI:N). π **Network**: Remote (AV:N).
Q6Is there a public Exp? (PoC/Wild Exploitation)
π« **Public Exp?**: No PoCs listed in data. π΅οΈ **Status**: Theoretical/Logic-based. Wild exploitation likely low due to high complexity requirement.
Q7How to self-check? (Features/Scanning)
π **Check**: Scan for Clerk SDK versions 4.7.0-4.29.3 in `package.json`. π§ͺ **Test**: Review usage of `auth()`/`getAuth()` for improper permission checks.
Q8Is it fixed officially? (Patch/Mitigation)
β **Fixed**: Yes! Patched in **v4.29.3**. π₯ **Action**: Upgrade immediately to the latest stable version via npm/yarn.
Q9What if no patch? (Workaround)
π οΈ **Workaround**: If stuck, manually implement strict server-side permission checks. Never trust client-side auth state blindly. π§ **Mitigate**: Restrict access to sensitive endpoints.
Q10Is it urgent? (Priority Suggestion)
π₯ **Urgency**: HIGH. π **CVSS**: 9.1 (Critical). β‘ **Priority**: Patch ASAP. Logic flaws in auth are dangerous for any web app relying on Clerk.
