EPSS

• CVE-2025-25295: 0.76% estimated exploitation activity in the next 30 days; percentile 55.35 (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.

Description A path traversal vulnerability in Label Studio SDK versions prior to 1.0.10 allows unauthorized file access outside the intended directory structure. Label Studio versions before 1.16.0 specified SDK versions prior to 1.0.10 as dependencies, and the issue was confirmed in Label Studio version 1.13.2.dev0; therefore, Label Studio users should upgrade to 1.16.0 or newer to mitigate it. The flaw exists in the VOC, COCO and YOLO export functionalites. These functions invoke a download function on the label-studio-sdk python package, which fails to validate file paths when processing image references during task exports: By creating tasks with path traversal sequences in the image field, an attacker can force the application to read files from arbitrary server filesystem locations when exporting projects in any of the mentioned formats. Note that there are two different possible code paths leading to this result, one for the isuploadedfile and another one for the islocalfile.…

# Patch Next advisory brief: CVE-2025-25295

Advisory: Label Studio has a Path Traversal Vulnerability via image Field
IDs: CVE-2025-25295, GHSA-rgv9-w7jp-m23g
Record: https://patchnext.com/advisories/cve-2025-25295 (revision 3, source checked 26 Oct 2026, 13:31 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.7)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: label-studio-sdk 1.0.10. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI label-studio-sdk: affected < 1.0.10; fixed in 1.0.10

## Suggested inspection (read-only)
- `python -m pip show label-studio-sdk`: 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 label-studio-sdk.
- 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.

## Sources
