CVE-2025-61726

A flaw was found in the net/url package in the Go standard library. The package does not enforce a limit on the number of unique query parameters it parses. A Go application using the net/http.Request.ParseForm method will try to process all parameters provided in the request. A specially crafted HTTP request containing a massive number of query parameters will cause the application to consume an excessive amount of memory, eventually causing the application to crash or become unresponsive, resulting in a denial of service.

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

Vendor Fix To start using the Web Terminal Operator, install the Web Terminal Operator from OpenShift OperatorHub on OpenShift Container Platform 4.20 or higher. https://access.redhat.com/errata/RHSA-2026:8167

Workaround Red Hat has investigated whether a possible mitigation exists for this issue, and has not been able to identify a practical example. Please update the affected package as soon as possible.

CVE-2025-61729

A flaw was found in golang. A remote attacker could exploit this vulnerability by providing a specially crafted certificate during the error string construction process within the `HostnameError.Error()` function. This flaw, caused by unbounded string concatenation, leads to excessive resource consumption. Successful exploitation can result in a denial of service (DoS) for the affected system.

7.5 (High)


                        
                          CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

CWE-1050 - Excessive Platform Resource Consumption within a Loop

CVE-2025-68121

A flaw was found in the crypto/tls component. This vulnerability occurs during Transport Layer Security (TLS) session resumption when certificate authority (CA) settings are modified between the initial and resumed handshakes. An attacker could exploit this to bypass certificate validation, allowing a client or server to establish a connection that should have been rejected. This could lead to an authentication bypass under specific conditions.

7.4 (High)


                        
                          CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N

CVE-2026-25679

The Go standard library function net/url.Parse insufficiently validated the host/authority component and accepted some invalid URLs by effectively treating garbage before an IP-literal as ignorable. The function should have rejected this as invalid.

7.5 (High)


                        
                          CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

CWE-1286 - Improper Validation of Syntactic Correctness of Input

Workaround Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.

CVE-2026-27137

A certificate validation flaw has been discovered in the golang crypto/x509 module. When verifying a certificate chain which contains a certificate containing multiple email address constraints which share common local portions but different domain portions, these constraints will not be properly applied, and only the last constraint will be considered.

7.5 (High)


                        
                          CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

CWE-295 - Improper Certificate Validation

CVE-2025-61729 (GCVE-0-2025-61729)

Vulnerability from cvelistv5 – Published: 2025-12-02 18:54 – Updated: 2025-12-03 19:37

Title

Excessive resource consumption when printing error string for host certificate validation in crypto/x509

Summary

Within HostnameError.Error(), when constructing an error string, there is no limit to the number of hosts that will be printed out. Furthermore, the error string is constructed by repeated string concatenation, leading to quadratic runtime. Therefore, a certificate provided by a malicious actor can result in excessive resource consumption.

Severity ?

7.5 (High)

CVE-2025-68121 (GCVE-0-2025-68121)

Vulnerability from cvelistv5 – Published: 2026-02-05 17:48 – Updated: 2026-02-20 16:05

Title

Unexpected session resumption in crypto/tls

Summary

During session resumption in crypto/tls, if the underlying Config has its ClientCAs or RootCAs fields mutated between the initial handshake and the resumed handshake, the resumed handshake may succeed when it should have failed. This may happen when a user calls Config.Clone and mutates the returned Config, or uses Config.GetConfigForClient. This can cause a client to resume a session with a server that it would not have resumed with during the initial handshake, or cause a server to resume a session with a client that it would not have resumed with during the initial handshake.

Severity ?

CVE-2025-61726 (GCVE-0-2025-61726)

Vulnerability from cvelistv5 – Published: 2026-01-28 19:30 – Updated: 2026-01-29 18:31

Title

Memory exhaustion in query parameter parsing in net/url

Summary

The net/url package does not set a limit on the number of query parameters in a query. While the maximum size of query parameters in URLs is generally limited by the maximum request header size, the net/http.Request.ParseForm method can parse large URL-encoded forms. Parsing a large form containing many unique query parameters can cause excessive memory consumption.

Severity ?

7.5 (High)
