The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper validation of archive/zip in Go programming language when processing archive header. A remote attacker can pass a specially crafted file to the application and perform a denial of service (DoS) attack.
2) Input validation error (CVE-ID: CVE-2021-29923)
The vulnerability allows a remote attacker to bypass implemented security restrictions.

bypass access control that is based on IP addresses, because of
unexpected octal interpretation.
3) Buffer overflow (CVE-ID: CVE-2021-38297)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error. A remote attacker can trigger memory corruption via large arguments in a function invocation from a WASM module, when GOARCH=wasm GOOS=js is used.
4) Resource exhaustion (CVE-ID: CVE-2021-33196)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources when parsing archives. A remote attacker can pass a specially crafted .zip file to the application, trigger resource exhaustion and perform a denial of service (DoS) attack.
