Description

This security bulletin contains information about 1 vulnerability.


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.
