Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: Capsule (K8s multi-tenant framework) has a **Namespace Label Injection** flaw. ๐ **Consequences**: Leads to **Privilege Escalation** and **Cross-Tenant Resource Access**.โฆ
๐ก๏ธ **Root Cause**: **CWE-863** (Incorrect Authorization). The system fails to properly validate namespace labels, allowing injection attacks that bypass security boundaries. ๐ง **Flaw**: Logic error in policy enforcement.
Q3Who is affected? (Versions/Components)
๐ฆ **Affected**: **Project Capsule**. ๐ **Version**: **0.10.3 and earlier**. If you are running older versions, you are at risk! โ ๏ธ
Q4What can hackers do? (Privileges/Data)
๐ **Attacker Actions**: Hackers can **escalate privileges** beyond their assigned role. They can access resources belonging to **other tenants**, breaking isolation. ๐ต๏ธโโ๏ธ
Q5Is exploitation threshold high? (Auth/Config)
๐ **Threshold**: **Medium**. Requires **Low Privileges** (PR:L) and **User Interaction** (UI:R). Network access is possible (AV:N). Not zero-click, but easy for insiders or compromised accounts. ๐ฏ
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ซ **Public Exploit**: **No**. The `pocs` field is empty. No public Proof-of-Concept or wild exploitation code available yet. ๐ต๏ธโโ๏ธ
Q7How to self-check? (Features/Scanning)
๐ **Self-Check**: Scan for **Capsule version < 0.10.3**. Check for **namespace label injection** patterns in your K8s policies. Use SAST/DAST tools to find authorization flaws. ๐งช
Q8Is it fixed officially? (Patch/Mitigation)
โ **Fixed**: **Yes**. A fix is available via the official GitHub commit: `e1f47feade6e1695b2204407607d07c3b3994f6e`. Update immediately! ๐ ๏ธ
Q9What if no patch? (Workaround)
๐ง **No Patch?**: If you cannot update, **strictly validate namespace labels** before processing. Implement **manual policy checks** to prevent injection. Monitor logs for anomalous label changes. ๐
Q10Is it urgent? (Priority Suggestion)
๐ฅ **Urgency**: **HIGH**. CVSS Score is **High** (H/H/H). Even without public exploits, the impact is severe. Patch as soon as possible to protect tenant isolation. ๐โโ๏ธ
