CVE-2026-35466: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in CERT/CC cveClient/cveInterface.js
CVE-2026-35466 is a cross-site scripting (XSS) vulnerability in the cveClient/cveInterface. js component of CERT/CC. The vulnerability arises because the script improperly neutralizes input during web page generation, allowing injected HTML from CVE API services to be passed to the display. This can lead to partial compromise of confidentiality and integrity via reflected XSS. The vulnerability has a CVSS score of 6. 1 (medium severity). No patch or official remediation information is currently available.
AI Analysis
Technical Summary
This vulnerability is classified as CWE-79 (Improper Neutralization of Input During Web Page Generation). The cveInterface.js script trusts input from CVE API services without sufficient sanitization, enabling injection of malicious HTML content. This reflected cross-site scripting flaw could allow an attacker to execute arbitrary scripts in the context of the affected web page, potentially leading to limited confidentiality and integrity impacts. The CVSS vector indicates the attack is network-based, requires no privileges, but requires user interaction, and affects confidentiality and integrity with a scope change.
Potential Impact
Successful exploitation could allow an attacker to inject and execute malicious scripts in the context of the affected web interface, potentially leading to partial disclosure or modification of information accessible to the user. There is no indication of availability impact. The vulnerability does not require privileges but does require user interaction. No known exploits are reported in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should exercise caution when interacting with the affected component and consider implementing input sanitization or output encoding as a temporary mitigation. Monitor CERT/CC advisories for updates on patches or official mitigations.
