Description

There is a Stored XSS vulnerability in the glance node module versions <= 3.0.5. File name, which contains malicious HTML (eg. embedded iframe element or javascript: pseudo-protocol handler in <a> element) allows to execute JavaScript code against any user who opens a directory listing containing such crafted file name.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for glance, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update glance to 3.0.8 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-7375-vjr2-3g7w is resolved across your whole dependency graph.

  3. Workarounds

    Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.

Frequently Asked Questions

Versions of `glance` before 3.0.8 are vulnerable to Stored Cross-Site Scripting (XSS). This is only exploitable if the attacker is able to control the name of a file that is served by the `glance` package.
