Description

This security bulletin contains information about 5 vulnerabilities.


1) Input validation error (CVE-ID: CVE-2026-25679)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to bypass URL parsing validation and potentially access unintended resources.

The vulnerability exists due to insufficient validation in net/url.Parse when handling IPv6 literals not located at the start of the host component. A remote attacker can send a specially crafted URL with an IPv6 literal preceded by garbage characters to bypass proper parsing and potentially redirect requests.

This issue affects any application using net/url.Parse to process untrusted URLs. The incorrect parsing may lead to misrouting or injection of unintended host components.


2) Resource exhaustion (CVE-ID: CVE-2026-32280)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: 8.7 [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]


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to uncontrolled resource consumption in the Certificate.Verify chain-building logic in crypto/x509 when processing a large number of intermediate certificates supplied through VerifyOptions.Intermediates. A remote attacker can provide a large number of intermediate certificates to cause a denial of service.

This affects both direct users of crypto/x509 and users of crypto/tls.


3) Double free (CVE-ID: CVE-2026-33811)

CWE-ID: CWE-415 - Double Free

CVSSv4: 8.7 [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]


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to double free in net.LookupCNAME and Resolver.LookupCNAME when processing a very long CNAME response with the cgo DNS resolver. A remote attacker can send a specially crafted DNS response to cause a denial of service.


4) Resource exhaustion (CVE-ID: CVE-2026-42499)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: 8.7 [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]


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to uncontrolled resource consumption in net/mail consumePhrase when parsing an email address according to RFC 5322. A remote attacker can supply a pathological email address input to cause a denial of service.


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

CWE-ID: CWE-295 - Improper Certificate Validation

CVSSv4: 9.3 [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]


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
