**According to the CVSS metrics, successful exploitation of this vulnerability could lead to no loss of confidentiality (C:N) but have major impact on integrity (I:H) and on availability (A:H). What does that mean for this vulnerability?** This vulnerability does not allow disclosure of any confidential information, but could allow an attacker to delete data that could include data that results in the service being unavailable.
**According to the CVSS metric, the attack complexity is high (AC:H). What does that mean for this vulnerability?** Successful exploitation of this vulnerability requires an attacker to win a race condition.

### Summary An unsafe reading of environment file could potentially cause a denial of service in Netty. When loaded on an Windows application, Netty attemps to load a file that does not exist. If an attacker creates such a large file, the Netty application crash. ### Details A similar issue was previously reported in https://github.com/netty/netty/security/advisories/GHSA-xq3w-v528-46rv This issue was fixed, but the fix was incomplete in that null-bytes were not counted against the input limit. ### PoC The PoC is the same as for https://github.com/netty/netty/security/advisories/GHSA-xq3w-v528-46rv with the detail that the file should only contain null-bytes; 0x00. When the null-bytes are encountered by the `InputStreamReader`, it will issue replacement characters in its charset decoding, which will fill up the line-buffer in the `BufferedReader.readLine()`, because the replacement character is not a line-break character. ### Impact Impact is the same as https://github.com/netty/ne...
OpenAI's latest tech can reason better than its previous models could, but not well enough to ferret out careful social engineering.

### Summary While pushing a file via postLocal method if user add javascript code in file parameter that codes can exe in v8go context. ### Details While posting a file via postLocal, any attacker will add javascript codes to file parameter. That parameter content pass to componentSignature method after some validation.

Thanks to v8go we can't use all javascript metod, if there is no any vulnerability in v8go we can't escape sandbox and can't run dangerous command like opening socket etc. But we can create infinite loop ...
