Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: MyTube (v1.7.66-) has a broken auth check. ๐ **Consequences**: Attackers bypass `roleBasedAuthMiddleware` to access/modify settings & protected routes without permission.
Q2Root Cause? (CWE/Flaw)
๐ก๏ธ **Root Cause**: **CWE-863** (Incomplete Correct Authorization). The middleware fails to properly verify user roles before granting access to sensitive endpoints.
Q3Who is affected? (Versions/Components)
๐ฅ **Affected**: **MyTube** by **franklioxygen** (Peifan Li). ๐ฆ **Version**: All versions **before 1.7.66**.
Q4What can hackers do? (Privileges/Data)
๐ **Attacker Power**: Full control over **App Settings** & **Protected Routes**. ๐ **Impact**: High Confidentiality, Integrity, & Availability loss (CVSS H/I/A: H).
Q5Is exploitation threshold high? (Auth/Config)
๐ **Threshold**: **LOW**. โ๏ธ **Config**: No auth required (`PR:N`), Network accessible (`AV:N`), Low complexity (`AC:L`). Easy to exploit remotely.
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐งช **Exploit**: **No public PoC** listed in data. ๐ **Wild Exp**: Unlikely widespread yet, but the flaw is critical. Check GitHub advisories for updates.
Q7How to self-check? (Features/Scanning)
๐ **Self-Check**: Scan for MyTube instances. ๐งช **Test**: Attempt to access protected routes/settings without valid session/role tokens. If accessible, you are vulnerable.
Q8Is it fixed officially? (Patch/Mitigation)
โ **Fixed**: **YES**. ๐ **Patch**: Released **2026-01-19**. ๐ ๏ธ **Action**: Update to **v1.7.66** or later. See GitHub Advisory GHSA-cmvj-g69f-8664.
Q9What if no patch? (Workaround)
๐ง **No Patch?**: Isolate the instance. ๐ซ **Block**: Restrict network access to untrusted zones. ๐ **Manual**: Audit `roleBasedAuthMiddleware` code if self-hosting.
Q10Is it urgent? (Priority Suggestion)
๐ฅ **Urgency**: **CRITICAL**. ๐ **Priority**: **P1**. Immediate patching required due to remote, unauthenticated, high-impact nature. Don't wait!
