Description
This security bulletin contains information about 5 vulnerabilities.
1) Cross-site scripting (CVE-ID: CVE-2026-42338)
CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
CVSSv4: 5.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N]
The vulnerability allows a remote attacker to execute arbitrary script in a victim\'s browser.
The vulnerability exists due to cross-site scripting in Address6.group(), Address6.link(), and AddressError.parseMessage handling when rendering untrusted Address6 input or related HTML output as HTML. A remote attacker can supply crafted input or option values to inject script and execute arbitrary script in a victim\'s browser.
User interaction is required because a victim application must render the returned HTML or parseMessage as HTML.
2) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2026-12151)
CWE-ID: CWE-770 - Allocation of Resources Without Limits or Throttling
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 allocation of resources without limits or throttling in the WebSocket client message fragmentation handling when processing fragmented WebSocket messages from a server. A remote attacker can send many small or empty continuation frames to cause a denial of service.
Exploitation requires the application to connect to an attacker-controlled or compromised WebSocket endpoint using the WebSocket client or the WebSocketStream API.
3) Integer overflow (CVE-ID: CVE-2026-48933)
CWE-ID: CWE-190 - Integer overflow
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 integer overflow in the WebCrypto subtle.encrypt() implementation when processing input whose size is a multiple of 2 gib. A remote attacker can supply crafted input to cause a denial of service.
4) Inclusion of Sensitive Information in Log Files (CVE-ID: CVE-2026-48615)
CWE-ID: CWE-532 - Information Exposure Through Log Files
CVSSv4: 5.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a remote user to disclose sensitive information.
The vulnerability exists due to improper handling of sensitive information in ERR_PROXY_TUNNEL error messages when processing proxy URLs with embedded credentials. A remote user can trigger an error handling path to disclose sensitive information.
The exposed data may be captured by logs, diagnostics, or other error consumers.
5) Input validation error (CVE-ID: CVE-2026-48618)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: 8.8 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:L/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to bypass tls wildcard-depth authentication.
The vulnerability exists due to improper input validation in TLS hostname handling when normalizing hostnames with unicode dot separators. A remote attacker can present a crafted hostname to bypass tls wildcard-depth authentication.
This can lead to confidentiality impact or bypass of the intended security boundary under affected configurations.
