SB2026080107 - Cross-site scripting in jsoup

Description

This security bulletin contains information about 1 vulnerability.

1) Cross-site scripting (CVE-ID: N/A)

CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

CVSSv4: 2.1 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N]

The vulnerability allows a remote attacker to conduct cross-site scripting.

The vulnerability exists due to improper neutralization of input during web page generation in the jsoup Cleaner when sanitizing malformed HTML with a custom Safelist that permits raw-text elements. A remote attacker can supply specially crafted HTML to conduct cross-site scripting.

User interaction is required to render the serialized output, and jsoup built-in Safelists are unaffected.

Remediation

Install update from vendor's website.
