CVE-2026-4660

A flaw was found in the go-getter library. A remote attacker could exploit this vulnerability by providing a maliciously crafted URL during certain git operations. This could allow the attacker to perform arbitrary file reads on the file system, potentially leading to the disclosure of sensitive information.

7.5 (High)

CVE-2026-32280

A flaw was found in the Go standard library packages `crypto/x509` and `crypto/tls`. During the process of building a certificate chain, an attacker can provide a large number of intermediate certificates. This excessive input is not properly limited, leading to an uncontrolled amount of work being performed. This can result in a denial of service (DoS) condition, making the affected system or application unavailable to legitimate users.

7.5 (High)
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
CWE-770 - Allocation of Resources Without Limits or Throttling

Threats
Impact Important
CVE-2026-33810

A flaw was found in the `crypto/x509` package within Go (golang). When verifying a certificate chain, excluded DNS (Domain Name System) constraints are not correctly applied to wildcard DNS Subject Alternative Names (SANs) if the case of the SAN differs from the constraint. This oversight could allow an attacker to bypass certificate validation, potentially leading to the acceptance of a malicious certificate that should have been rejected. This issue specifically impacts the validation of trusted certificate chains.

8.8 (High)
CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:L
CWE-1289 - Improper Validation of Unsafe Equivalence in Input
