CVE-2025-53465
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 raoinfotech GSheets Connector sheetlink allows Object Injection.This issue affects GSheets Connector: from n/a through <= 1.1.1.
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 confidenceThe GSheets Connector (sheetlink) plugin by raoinfotech contains a deserialization vulnerability where untrusted data is being deserialized without proper validation, allowing remote attackers to inject malicious objects into the application context and potentially achieve code execution.

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 GSheets Connector plugin presenceLocate the raoinfotech sheetlink plugin files in the application plugins or extensions directory, or query the plugin management system if availableAffected if The plugin files are found in the environment
-
Identify installed plugin versionCheck the plugin metadata, version manifest, or pom.xml/build.gradle file within the plugin directory for the exact version stringAffected if The installed version matches or falls within any known affected version range for this CVE
-
Verify deserialization endpoint exposureInspect the plugin routing configuration or web.xml to identify endpoints that accept serialized data input (look for handlers processing Java serialized objects, Gson/Jackson with type handling, or custom deserializers)Affected if An endpoint exists that accepts and deserializes untrusted input without strict type filtering
-
Review deserialization configurationExamine the plugin configuration files for any settings related to data import, serialization, or object reconstruction from external sourcesAffected if Configuration allows or enables deserialization of data from untrusted sources without validation
-
Check for unsafe deserialization implementationSearch plugin source code for ObjectInputStream, readObject(), JSON.parseObject() with no type whitelist, or similar deserialization patterns handling user inputAffected if Code implements unsafe deserialization that processes data from user-supplied sources
The environment is affected if the GSheets Connector plugin is installed and its deserialization functionality is exposed to untrusted input without strict class whitelisting or input 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 dataReplace unsafe deserialization with safer formats like JSON; implement strict class whitelisting or type checking on any deserialized data; validate and sanitize all user-supplied input before deserialization.
