GHSA-2wwr-9x6f-88gp
MEDIUMGHSA-2wwr-9x6f-88gp is a medium-severity (CVSS 5.3) vulnerability in easycorp/easyadmin-bundle. O3 Security confirms whether GHSA-2wwr-9x6f-88gp is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
EasyAdminBundle has path traversal and reflected XSS in Flag and Icon Twig components
Real-World Exposure
easycorp/easyadmin-bundle🐘easycorp/easyadmin-bundleReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.
Description
EasyAdminBundle ships two public Twig components — <twig:ea:Flag countryCode="..."> and <twig:ea:Icon name="..."> — that load SVG files from disk using a path built directly from a public component property, and then render the resulting markup with the Twig |raw filter.
When an application binds either of those properties to data that is influenced by an end user, the lack of validation on the property value leads to two distinct issues:
- Arbitrary
.svgfile disclosure (both components) — the property value is concatenated into a filesystem path without normalizing or constraining it, so..segments are preserved and resolved by PHP. Any file on the server whose absolute path ends in.svg(for example, user-uploaded SVG icons stored elsewhere on the host) can be read and embedded into the rendered page. - Reflected XSS in the admin UI (Flag component only) — when the requested flag file does not exist, the Flag component falls back to a hard-coded SVG string that interpolates the raw
countryCodevalue twice, and the parent template renders that string with|raw. An attacker who controlscountryCodecan therefore inject arbitrary HTML/JavaScript that will execute inside the authenticated admin context that rendered the component.
The first-party usage shipped by EasyAdminBundle itself is not affected: the bundle only passes ISO 3166 alpha-2 codes validated through Symfony\Component\Intl\Countries to the Flag component, and only hard-coded internal:.. names or values previously set in PHP via MenuItem::setIcon() to the Icon component. The vulnerability is reachable only in third-party templates that pass attacker-controlled data into these properties.
Impact
Path traversal is information disclosure bounded by the .svg extension; reflected XSS in Flag runs in the admin context and is therefore more sensitive but requires a vulnerable template wiring and user interaction.
Affected components

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for easycorp/easyadmin-bundle. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update easycorp/easyadmin-bundle to 4.29.10 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-2wwr-9x6f-88gp is resolved across your whole dependency graph.
Workarounds
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 pinpoints whether GHSA-2wwr-9x6f-88gp is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-2wwr-9x6f-88gp. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
