Summary

Improper Neutralization of Input During Web Page Generation (XSS or 'Cross-site Scripting') vulnerability in Wikimedia Foundation timeline. This vulnerability is associated with program files includes/Timeline.

Php, scripts/EasyTimeline.Pl. This issue affects timeline: from * before 1.46.0, 1.45.4, 1.44.6, 1.43.9.

A flaw was found in the Wikimedia Foundation Timeline component. This cross-site scripting (XSS) vulnerability allows a remote attacker to inject malicious scripts into web pages.

Successful exploitation could lead to significant impacts such as information disclosure, session hijacking, or defacement of affected web pages.

While a remote attacker could inject malicious scripts, successful exploitation typically requires specific user interaction or a highly customized environment, limiting its broader applicability in standard Red Hat deployments. Red Hat severity: Low — CVSS 3.7 (CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:L/I:L/A:N).

Weakness: CWE-79.
