Description

This security bulletin contains information about 4 vulnerabilities.


1) Input validation error (CVE-ID: CVE-2025-61728)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input when parsing zip archives. A remote attacker can pass specially crafted zip archive to the application and perform a denial of service (DoS) attack.


2) Resource exhaustion (CVE-ID: CVE-2025-61726)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


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 within the Request.ParseForm method in net/http when parsing a URL-encoded form. A remote attacker can pass an overly large request with a large number of key-value pairs and consume all available memory on the system. 


3) Code Injection (CVE-ID: CVE-2025-61732)

CWE-ID: CWE-94 - Improper Control of Generation of Code ('Code Injection')

CVSSv4: CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:A/VC:N/VI:N/VA:N/SC:H/SI:H/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to inject arbitrary code into the application.

The vulnerability exists due to improper input validation in cmd/cgo caused by discrepancy between how Go and C/C++ comments are parsed. A remote attacker can smuggle code into the resulting cgo binary.


4) Improper Certificate Validation (CVE-ID: CVE-2025-68121)

CWE-ID: CWE-295 - Improper Certificate Validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote attacker to compromise the target system.

The vulnerability exists due to improper certificate validation within HTTP/3 connections. A remote attacker can cause cause a client to resume a session with a server that it would not have resumed with during the initial handshake
