CVE-2024-48026
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 · uneditedDeserialization of Untrusted Data vulnerability in GMRobbins Disc Golf Manager disc-golf-manager allows Object Injection.This issue affects Disc Golf Manager: from n/a through <= 1.0.0.
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 confidenceThis is a PHP Object Injection vulnerability in the Disc Golf Manager application stemming from unsafe deserialization of untrusted data. Attackers can exploit this by sending crafted serialized PHP objects to vulnerable endpoints, potentially triggering magic methods to achieve remote code execution, file operations, or other malicious actions.

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 Disc Golf Manager installationSearch the web server document root or application directory for files belonging to the Disc Golf Manager application. Look for typical PHP application structures (index.php, config files, src directories).Affected if The application is present on the system
-
Locate PHP deserialization callsSearch the codebase for usage of PHP's unserialize() function. Use grep or similar: grep -r "unserialize" /path/to/application/ --include="*.php"Affected if The code contains unserialize() calls without strict type checking or allowlist validation
-
Verify user input reaches deserializationExamine the unserialize() calls found to determine if any user-controlled data (POST parameters, GET parameters, cookies, JSON body content) is passed as the input to unserialize(). Review the data flow from HTTP request to the deserialization sink.Affected if Untrusted user input flows directly into unserialize() without prior validation
-
Check for magic method classesInspect class definitions in the application for __wakeup, __destruct, __toString, or other magic methods that could be triggered during deserialization. These methods may contain sensitive operations (file operations, shell commands, database queries).Affected if Classes with dangerous magic methods exist in the application and are reachable by the attacker through the deserialization sink
-
Identify exposed endpoints accepting serialized dataReview API endpoints, forms, and other input points that accept serialized data. Check if these endpoints are accessible without authentication or if authentication can be bypassed.Affected if Endpoints that accept and deserialize data are publicly accessible or accept input from untrusted sources
A user is affected if the Disc Golf Manager application is deployed, contains unserialize() calls that process user-supplied data without validation, and has classes with exploitable magic methods accessible via those deserialization sinks.

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 dataReplace any usage of unserialize() with safer alternatives like JSON encoding, implement strict allowlist validation on any deserialized data, and audit all user-controlled input paths for deserialization sinks.
