Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: Pipecat (v0.0.41-0.0.93) suffers from **Unsafe Deserialization**. ๐ **Consequence**: Attackers can achieve **Remote Code Execution (RCE)** by injecting malicious payloads into WebSocket streams.โฆ
๐ฅ **Affected**: Users of **Pipecat** framework. ๐ **Versions**: **0.0.41** through **0.0.93**. ๐ข **Vendor**: pipecat-ai. โ ๏ธ Check your version immediately!
Q4What can hackers do? (Privileges/Data)
๐ **Hacker Power**: Full **Remote Code Execution**. ๐ **Access**: Can read/modify any data, install backdoors, or pivot to other systems. ๐ **Privileges**: Runs with the same rights as the Pipecat process.โฆ
โก **Threshold**: **LOW**. ๐ **Auth**: None required (PR:N). ๐ฑ๏ธ **UI**: None required (UI:N). ๐ก **Vector**: Network (AV:N). ๐ฏ Any remote attacker can exploit this via WebSocket connections.
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ซ **Public Exploit**: No specific PoC code provided in the data. ๐ **Reference**: GitHub Security Advisory (GHSA-c2jg-5cp7-6wc7) confirms the flaw.โฆ
๐ **Self-Check**: Scan for `pickle.loads` in `LivekitFrameSerializer`. ๐ก Monitor WebSocket traffic for unexpected binary payloads. ๐ ๏ธ Use SAST tools to detect unsafe deserialization patterns in Python code.โฆ
๐ง **No Patch?**: **Disable** WebSocket deserialization if possible. ๐ซ **Block** `pickle` usage entirely; switch to JSON or MessagePack. ๐ **Isolate**: Run Pipecat in a restricted container/sandbox.โฆ
๐ฅ **Urgency**: **CRITICAL**. ๐จ CVSS Score: **9.8** (High). โณ **Priority**: Patch immediately. This is a trivial RCE vector with no authentication needed. Do not wait for an exploit to appear; the flaw is fundamental.
