CVE-2025-52826
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 uxper Sala allows Object Injection. This issue affects Sala: from n/a through 1.1.3.
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 confidenceA deserialization vulnerability in uxper Sala allows attackers to inject arbitrary PHP objects by supplying malicious serialized data. This object injection can potentially lead to remote code execution if exploitable gadget chains exist in the application or its dependencies.

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 uxper Sala installationSearch for the uxper Sala application in the system using file system queries or package managers (e.g., 'find / -name '*sala*' 2>/dev/null', 'dpkg -l | grep sala', or 'rpm -qa | grep sala')Affected if The application is present on the system and is using deserialization functionality without validation
-
Determine installed versionLocate version information from application metadata, configuration files, or executable version strings (e.g., check installation directories, README files, or run 'sala --version' if available)Affected if The installed version falls within any affected version range (compare to vendor release notes for CVE-2025-52826)
-
Inspect application deserialization codeSearch source code or binary for deserialization methods such as PHP unserialize(), Python pickle.load(), Java ObjectInputStream, or similar language-specific deserialization functionsAffected if The application deserializes data from untrusted sources without validation or class whitelisting
-
Review serialized data handling configurationsExamine configuration files, API endpoints, or data import features that accept serialized input (look for settings related to data import, backup restore, or API data processing)Affected if The application accepts serialized data from user input, external files, or network sources without cryptographic integrity checks
-
Check for secure deserialization alternativesVerify whether the application uses safer data formats like JSON, XML with schema validation, or signed/encrypted serialized payloadsAffected if The application relies on unsafe native serialization (pickle, PHP serialize, Java serialization) without additional protections
A user is affected if uxper Sala is installed and processes untrusted serialized data without proper validation, class whitelisting, or integrity verification.

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 PHP unserialize() calls with JSON-based deserialization or implement a strict allowed_classes whitelist; validate and sanitize all user-supplied data before deserialization.
