Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: Grist < 1.7.9 has an **Injection Vulnerability**. ๐ **Consequences**: Attackers can bypass the **Pyodide sandbox** and execute **arbitrary processes** on the server. ๐ฅ Impact is Critical (CVSS High).
Q2Root Cause? (CWE/Flaw)
๐ก๏ธ **Root Cause**: **CWE-74** (OS Command Injection). ๐ **Flaw**: The **Pyodide sandbox barrier** is insufficient.โฆ
๐ข **Vendor**: **Grist Labs**. ๐ฆ **Product**: **grist-core**. ๐ **Affected Versions**: All versions **prior to 1.7.9**. โ **Fixed In**: 1.7.9 and later.
Q4What can hackers do? (Privileges/Data)
๐ **Privileges**: **High**. Attackers gain **Server-Side** access. ๐พ **Data**: Full **Confidentiality, Integrity, and Availability** loss. They can run **arbitrary commands**, effectively taking over the server.
Q5Is exploitation threshold high? (Auth/Config)
๐ **Auth**: **None Required** (PR:N). ๐ **Network**: **Remote** (AV:N). ๐ฏ **Complexity**: **High** (AC:H). While no login is needed, the attack vector is technically complex to exploit successfully.
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ **Public Exp**: **No**. The `pocs` field is empty. ๐ซ **Wild Exploit**: None reported. โ ๏ธ However, the CVSS score suggests high severity, so assume risk is real even without a public PoC.
Q7How to self-check? (Features/Scanning)
๐ **Check**: Scan for **Grist** instances. ๐ **Version**: Verify if running **< 1.7.9**. ๐ ๏ธ **Tool**: Use vulnerability scanners targeting **CWE-74** in Python/Pyodide environments.โฆ
๐ฅ **Urgency**: **Critical**. ๐จ **Priority**: **P1**. Even with High Complexity, the impact is **Full Server Compromise** with **No Auth**. Patch immediately upon upgrading to 1.7.9. โณ Time is of the essence.
