CVE-2026-7680: jsbroks COCO Annotator Data Endpoint datasets.py path traversal

A weakness has been identified in jsbroks COCO Annotator up to 0.11.1. Affected is an unknown function of the file backend/webserver/api/datasets.py of the component Data Endpoint. Executing a manipulation of the argument folder can lead to path traversal. The attack can be launched remotely. The exploit has been made available to the public and could be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.

Security readout for executives and security teams

Plain-English summary

COCO Annotator 0.11.0 and 0.11.1 contain a remotely reachable path-traversal weakness in a dataset endpoint. A low-privileged user may manipulate the dataset folder value to reach paths outside the intended location, creating a limited confidentiality risk. Public exploit material exists, but the supplied sources do not establish active exploitation.

Executive priority

Treat this as a moderate-priority confidentiality issue. Accelerate action for internet-accessible deployments, environments holding sensitive files, or broadly assigned user access. Restrict exposure immediately where practical, then track vendor or project guidance. Current evidence does not justify describing this as an actively exploited emergency.

Technical view

The weakness affects an unspecified function in backend/webserver/api/datasets.py within the Data Endpoint. Manipulating the folder argument can trigger CWE-22 path traversal. CVSS 4.0 rates it 5.3, with network access, low complexity, low privileges, no user interaction, and low confidentiality impact. No integrity or availability impact is identified.

Likely exposure

Exposure is most likely where COCO Annotator 0.11.0 or 0.11.1 is deployed and its Data Endpoint is accessible to untrusted or low-privileged users. Internet-accessible instances warrant faster review. The supplied evidence does not identify other affected versions, default exposure, authentication configuration, or the specific files obtainable.

Exploitation context

A public exploit reference is available, increasing the chance of attempted abuse. The CVSS vector indicates low privileges are required, so this is not documented as unauthenticated exploitation. CVE-2026-7680 is not listed as KEV in the supplied bundle, and no cited evidence confirms exploitation in the wild.

Researcher notes

The available description does not identify the exact function, vulnerable code path, accessible file scope, default authentication posture, or a fixed version. Vendor contact reportedly received no response. Assessment therefore relies on CWE-22, the CVSS vector, affected-version data, and the public research reference; avoid assuming arbitrary file access beyond demonstrated scope.

Mitigation direction

  • Inventory COCO Annotator deployments and prioritize versions 0.11.0 and 0.11.1.
  • Restrict the Data Endpoint to trusted networks and authorized users until remediation is available.
  • Apply least-privilege filesystem permissions to limit data accessible through the application.
  • Check current vendor or project guidance for a fixed release; no patch is identified in supplied sources.
  • Consider application-layer validation that confines folder values to approved dataset directories.

Validation and detection

  • Confirm deployed COCO Annotator versions from package, image, or build records.
  • Determine whether the Data Endpoint is reachable from untrusted networks or low-privileged accounts.
  • Review endpoint logs for anomalous folder values or access outside expected dataset locations.
  • Verify filesystem permissions prevent the service account from reading unnecessary sensitive files.
  • After remediation, confirm folder inputs cannot resolve beyond approved dataset directories.
