Title

SVGO: removeScripts incompletely sanitizes executable HTML in SVG foreignObject elements

Summary

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.

Summary

SVGO: removeScripts incompletely sanitizes executable HTML in SVG foreignObject elements

Details

Summary

SVGO's opt-in removeScripts plugin did not inspect executable HTML content inside SVG <foreignObject> elements. Applications that used this plugin as their only protection for untrusted SVG input could produce SVGs containing active HTML and expose users to cross-site scripting (XSS).

SVGO is an optimizer rather than a comprehensive sanitization library, but removeScripts is maintained for consumers that already rely on it to remove common script execution paths.

Details

Although the plugin removed SVG and XHTML <script> elements, it left other HTML execution paths inside <foreignObject> unchanged. These included:

event-handler attributes such as onload and onbeforetoggle;
srcdoc documents, including on <iframe> elements;
executable URLs in HTML attributes such as action, data, formaction, href, and src.

An attacker could place one of these payloads in an SVG. If an application optimized the untrusted SVG with removeScripts and then served the result in an active browser context, the payload could execute in the viewer's origin.

Impact

Successful exploitation could allow script execution in the context where the optimized SVG is rendered. Depending on the embedding and origin configuration, this could expose cookies or local storage, modify content, or perform actions as the victim.

The plugin is opt-in, so consumers that do not enable removeScripts are not relying on the affected behavior. Typical local optimization of trusted SVG files is not affected.

Patches

Upgrade to one of the following releases for the maintained release line in use:

Release line	Patched version	Plugin
v2	2.8.4	`removeScriptElement`
v3	3.3.5	`removeScriptElement`
v4	4.1.0	`removeScripts`

The fix preserves visual HTML inside SVG <foreignObject> elements while removing event attributes, srcdoc, and executable URL values from active HTML URL attributes.

SVGO v1 is no longer maintained. Users of v1 should upgrade to a supported release line.

Workarounds

For hostile input, use a dedicated SVG sanitization tool before passing the SVG to SVGO. As defense in depth, applications can reject or remove <foreignObject> content and avoid serving user-controlled SVGs in an active same-origin context.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
