CVE-2023-6026
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA Path traversal vulnerability has been reported in elijaa/phpmemcachedadmin affecting version 1.3.0. This vulnerability allows an attacker to delete files stored on the server due to lack of proper verification of user-supplied input.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidencePath traversal vulnerability in phpmemcachedadmin 1.3.0 allows deletion of arbitrary files on the server due to insufficient validation of user-supplied path input. An attacker can manipulate file paths to escape the intended directory and delete files outside the application's expected scope.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify if phpmemcachedadmin is installedLook for the phpmemcachedadmin directory in your web server's document root or check your application's dependency manifest (e.g., composer.json, package.json) for phpmemcachedadminAffected if phpmemcachedadmin is present in your environment
-
Verify the installed versionCheck the version file or header within the phpmemcachedadmin installation. Common locations include a VERSION file, the main index.php file, or the composer.json if managed as a dependencyAffected if The installed version is 1.3.0
-
Confirm access to the file deletion functionalityLocate the script or endpoint that handles memcache data management. Identify if there is a delete or flush operation that accepts a file path parameterAffected if A file deletion or flush operation is accessible and accepts user-supplied path input
-
Check if the application validates path inputReview the source code of the deletion routine to see if it uses basename() or similar path sanitization, or whether it allows directory traversal sequences like ../ in the supplied pathAffected if Path input is accepted without sanitization or the validation does not prevent directory traversal
Your environment is affected if you have phpmemcachedadmin version 1.3.0 installed with the file deletion functionality exposed and lacking proper path validation.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement strict input validation and path sanitization to ensure user-supplied file paths do not traverse outside allowed directories. Use basename() or equivalent to strip directory components and validate against allowlists.
