CVE-2023-5414 — Icegram Icegram Express security vulnerability

Critical CVSS 9.1

The Icegram Express plugin for WordPress is vulnerable to Directory Traversal in versions up to, and including, 5.6.23 via the show_es_logs function. This allows administrator-level attackers to read the contents of arbitrary files on the server, which can contain sensitive information including those belonging to other sites, for example in shared hosting environments.

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.
