CVE intelligence and bounded remediation
CVE-2022-50953 — WordPress Plugin admin-word-count-column security vulnerability
WordPress Plugin admin-word-count-column 2.2 contains a local file read vulnerability that allows unauthenticated attackers to read arbitrary files by exploiting null byte injection in the path parameter. Attackers can send GET requests to download-csv.php with a crafted path parameter containing directory traversal sequences and null bytes to bypass file restrictions and read sensitive files like system configuration.

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.
