CVE-2025-31927
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 themeton Acerola allows Object Injection. This issue affects Acerola: from n/a through 1.6.5.
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 · low confidenceAcerola (a themeton product) contains a deserialization vulnerability where untrusted data is being deserialized, allowing an attacker to inject malicious PHP objects. This type of flaw can lead to remote code execution depending on the application context and available gadget chains.

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 Acerola installationLocate the Acerola themeton product files in your webroot or application directory. Search for files named 'acerola' or directories belonging to this themeton product.Affected if Acerola themeton product is present in the environment
-
Determine Acerola versionCheck version files, composer.json, or any version metadata within the Acerola installation directory. Compare the installed version against any publicly disclosed fixed versions.Affected if The installed version is older than the patched version or no version information is available for comparison
-
Locate deserialization functionsSearch the Acerola source code for PHP deserialization functions such as unserialize, json_decode with deserialization flags, or any custom deserialization logic.Affected if The codebase contains deserialization functions that process untrusted input
-
Identify deserialization input sourcesInspect all entry points that feed data into deserialization functions, including request parameters, uploaded files, cookies, or API inputs.Affected if User-controlled data or external input is passed directly to deserialization functions without validation
-
Check for exposed deserialization endpointsReview application routes, API endpoints, and publicly accessible scripts that handle serialized data.Affected if Deserialization endpoints are accessible without authentication or additional security controls
-
Assess gadget chain availabilityReview third-party libraries and dependencies included with Acerola for known PHP gadget chains that could be chained with the deserialization flaw.Affected if The application includes libraries with exploitable gadget chains that could enable RCE through deserialization
The environment is affected if Acerola themeton product is installed and its codebase contains deserialization logic that processes untrusted input without 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 dataUpdate to the latest version of Acerola when a patch is released. If no patch is available, disable the affected component and implement strict input validation on all deserialization entry points.
