CVE-2026-39445
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 · uneditedUnauthenticated PHP Object Injection in Alukas < 3.0.0 versions.
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 confidenceUnauthenticated PHP Object Injection vulnerability in Alukas versions before 3.0.0 allows remote attackers to inject malicious serialized PHP objects through unsanitized user input, potentially enabling remote code execution via insecure deserialization.

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.
-
Confirm Alukas installationIdentify if the web application is Alukas by checking application files, headers, or documentation for the product nameAffected if The application is confirmed to be Alukas
-
Determine installed versionLocate the version identifier in the Alukas installation (such as a version file, composer.json, or admin panel about section) and record the exact version numberAffected if Version is present and is less than 3.0.0 (e.g., 2.x, 1.x)
-
Identify exposed user input pointsReview application endpoints or parameters that accept user-supplied data, particularly those that may handle serialized PHP data or appear in query strings, form inputs, or cookiesAffected if User input parameters are accessible without authentication and accept arbitrary data
-
Check for deserialization usageSearch application source code for PHP functions that perform deserialization (such as unserialize()) applied to user-controlled data from request parameters, cookies, or sessionsAffected if Code exists that deserializes data from unauthenticated user input sources
The environment is affected if Alukas version is confirmed to be below 3.0.0 and the application deserializes user-supplied data without validation.
Generated from the published advisory. Verify against your own configuration.
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 dataUpgrade Alukas to version 3.0.0 or later to obtain the security patch. If immediate upgrade is not possible, implement input validation to block serialized data in user-supplied parameters.
