Description
Snipe-IT v8.3.4 (build 20218) contains a reflected cross-site scripting (XSS) vulnerability in the CSV Import workflow. When an invalid CSV file is uploaded, the application returns a progress_message value that is rendered as raw HTML in the admin interface. An attacker can intercept and modify the POST /livewire/update request to inject arbitrary HTML or JavaScript into the progress_message. Because the server accepts the modified input without sanitization and reflects it back to the user, arbitrary JavaScript executes in the browser of any authenticated admin who views the import page. NOTE: this is disputed by the Supplier because the report only demonstrates that an authenticated user can choose to conduct a man-in-the-middle attack against himself.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for snipe/snipe-it, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Remediation status
No patched version of snipe/snipe-it has shipped for GHSA-8x9v-8qgj-945x yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-8x9v-8qgj-945x can be triaged on real exposure rather than presence alone.
Tailored to GHSA-8x9v-8qgj-945x. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-8x9v-8qgj-945x in your dependencies?
O3 Security finds GHSA-8x9v-8qgj-945x across Packagist dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
