EasyAdminBundle has path traversal and reflected XSS in Flag and Icon Twig components
GitHub lists this reviewed advisory for easycorp/easyadmin-bundle, easycorp/easyadmin-bundle. Published version ranges and source prerequisites are shown below; this is not an inspection of a visitor’s application.
This report has not inspected your inventory, configuration, deployed build, reachability or evidence. A catalog listing and a severity score do not establish exposure or compromise.
01 / Meaning
Why it matters
Published affected context helps an owner decide what evidence to gather. This report has not examined your application.
5.3 medium
GitHub source severity; exploitability and local consequence require separate evidence.

easycorp/easyadmin-bundle
source listed>= 4.0.0, < 4.29.10
EasyAdminBundle ships two public Twig components — `` and `` — 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 `.svg` file 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 `countryCode` value twice, and the parent template renders that string with `|raw`. An attacker who controls `countryCode` can therefore inject arbitrary HTML/JavaScript that will execu

What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database
- vendor patch
The original advisory lists fixed boundaries 4.29.10 for easycorp/easyadmin-bundle. Confirm the publisher’s latest guidance.

A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
