• CVE-2024-39903: 2.88% estimated exploitation activity in the next 30 days; percentile 86.89 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

A Local File Inclusion (LFI) vulnerability was identified in widgetti/solara, in version <1.35.1, which was fixed in version 1.35.1. This vulnerability arises from the application's failure to properly validate URI fragments for directory traversal sequences such as '../' when serving static files. An attacker can exploit this flaw by manipulating the fragment part of the URI to read arbitrary files on the local file system.

# Patch Next advisory brief: CVE-2024-39903

Advisory: Local File Inclusion in Solara
IDs: CVE-2024-39903, GHSA-9794-pc4r-438w
Record: https://patchnext.com/advisories/cve-2024-39903 (revision 2, source checked 26 Oct 2026, 13:16 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.6)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: solara 1.35.1. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI solara: affected < 1.35.1; fixed in 1.35.1

## Suggested inspection (read-only)
- `python -m pip show solara`: prints the installed version. Run with the environment that serves production active.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on solara.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
