CVE intelligence and bounded remediation

CVE-2024-56142 — pghoard is a PostgreSQL backup daemon and restore tooling that stores backup data in cloud object stores

Medium CVSS 6.5

pghoard is a PostgreSQL backup daemon and restore tooling that stores backup data in cloud object stores. A vulnerability has been discovered that could allow an attacker to acquire disk access with privileges equivalent to those of pghoard, allowing for unintended path traversal. Depending on the permissions/privileges assigned to pghoard, this could allow disclosure of sensitive information. This issue has been addressed in releases after 2.2.2a. Users are advised to upgrade. There are no known workarounds for this vulnerability.

Matched remediation archetype

Path traversal, unsafe upload, and file handling

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

Check exposure

  • Trace untrusted filenames, archive entries, URLs, and path segments into read, write, include, extraction, and upload operations.
  • Identify filesystem roots, mount permissions, symbolic-link behavior, archive handling, and whether uploaded content is web-accessible or executable.
  • Review canonicalization and containment checks across supported operating systems and storage backends.

Remediate safely

  • Generate server-side storage identifiers and resolve paths beneath a fixed root using filesystem-aware containment checks.
  • Reject absolute, parent-relative, alternate-separator, device, link, and archive entries that escape the intended root.
  • Store uploads outside executable or served paths, validate type and size, and use private atomic temporary files.
