CVE intelligence and bounded remediation

CVE-2022-26049 — This affects the package com.diffplug.gradle:goomph before 3.37.2

High CVSS 8.8

This affects the package com.diffplug.gradle:goomph before 3.37.2. It allows a malicious zip file to potentially break out of the expected destination directory, writing contents into arbitrary locations on the file system. Overwriting certain files/directories could allow an attacker to achieve remote code execution on a target system by exploiting this vulnerability. **Note:** This could have allowed a malicious zip file to extract itself into an arbitrary directory. The only file that Goomph extracts is the p2 bootstrapper and eclipse metadata files hosted at eclipse.org, which are not malicious, so the only way this vulnerability could have affected you is if you had set a custom bootstrap zip, and that zip was malicious.

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.
