CVE intelligence and bounded remediation

CVE-2024-53276 — Home-Gallery.org is a self-hosted open-source web gallery to browse personal photos and videos

Medium CVSS 6.3

Home-Gallery.org is a self-hosted open-source web gallery to browse personal photos and videos. In 1.15.0 and earlier, an open CORS policy in app.js may allow an attacker to view the images of home-gallery when it is using the default settings. The following express middleware allows any website to make a cross site request to home-gallery, thus allowing them to read any endpoint on home-gallery. Home-gallery is mostly safe from cross-site requests due to most of its pages requiring JavaScript, and cross-site requests such as fetch() do not render javascript. If an attacker is able to get the path of the preview images which are randomized, an attacker will be able to view such a photo. If any static files or endpoints are introduced in the future that contain sensitive information, they will be accessible to an attacker website.

Matched remediation archetype

Information disclosure and sensitive data exposure

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace sensitive data through responses, errors, logs, metrics, traces, caches, exports, files, backups, and client bundles.
  • Identify affected subjects, tenants, retention windows, access controls, and downstream copies without opening unnecessary sensitive records.
  • Review metadata, timing, status, length, and existence signals as well as direct content disclosure.

Remediate safely

  • Minimize collection and output, apply field-level authorization and redaction at a centralized boundary, and return generic external errors.
  • Remove secrets and sensitive data from logs, artifacts, URLs, caches, and client-side bundles; rotate credentials that may have been exposed.
  • Update the affected component and add synthetic-data tests for response, error, observability, and export paths.
