DescriptionCVE.org

SVGO, short for SVG Optimizer, is a Node.js library and command-line application for optimizing SVG files. From version 1.0.0 until versions 2.8.4, 3.3.5, and 4.1.0, the opt-in removeScripts plugin, named removeScriptElement in versions 2 and 3 and implemented in plugins/removeScripts.js, removes SVG and XHTML script elements but does not inspect executable HTML content inside SVG foreignObject elements. Event-handler attributes such as onload and onbeforetoggle, srcdoc documents, and executable URLs in the action, data, formaction, href, and src attributes can remain in attacker-controlled SVG input. When an application uses the plugin as its only protection and serves the optimized SVG in an active browser context, the payload can execute script in the viewer's origin, expose data, modify content, or perform actions as the victim. This issue is fixed in versions 2.8.4, 3.3.5, and 4.1.0.

AnalysisAI

Cross-site scripting in SVGO's opt-in removeScripts plugin allows XSS payloads embedded inside SVG foreignObject elements to survive optimization unchanged. Applications that process attacker-supplied SVG through SVGO with this plugin enabled and then serve the output in a browser context are exposed: event-handler attributes, srcdoc iframe payloads, and executable URL schemes (javascript:, vbscript:, data:text/html) in action/data/formaction/href/src attributes all pass through unmodified. …

Vulnerability AssessmentAI

Exploitation Three conditions must all be true simultaneously. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 6.1 (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N) correctly models a stored/reflected XSS scenario: no privileges required to submit malicious SVG, but a victim must view the output in a browser (UI:R), and script executes in the application's origin (S:C). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation Upgrade to SVGO 2.8.4, 3.3.5, or 4.1.0 as appropriate for the installed major version; all three are confirmed by GitHub release tags. … Detailed patch versions, workarounds, and compensating controls in full report.
