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 · unedited
Deserialization of Untrusted Data vulnerability in baptiste.gourdin Talkback talkback-secure-linkback-protocol allows Object Injection.This issue affects Talkback: from n/a through <= 1.0.

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 confidence

A deserialization of untrusted data vulnerability in the Talkback talkback-secure-linkback-protocol library allows remote attackers to inject arbitrary objects via insecure deserialization. This object injection can potentially lead to remote code execution depending on the application's available gadget chains.

MitigationUpgrade to a patched version of Talkback if available; otherwise, validate and sanitize all deserialized input, implement allowlist-based deserialization, or disable the vulnerable linkback-protocol component until a fix is available.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify if Talkback is deployed
    Search your application dependencies, build artifacts, or installed packages for 'talkback' or 'talkback-secure-linkback-protocol'. Review your dependency management files (pom.xml, package.json, requirements.txt, build.gradle) or JAR/WAR archives.
    Affected if The talkback library or talkback-secure-linkback-protocol is present in your dependencies or deployed files.
  2. Determine the Talkback version
    Locate the specific version number of the talkback-secure-linkback-protocol library in your dependency manifest or JAR metadata. Check the POM file, manifest, or version in your package manager.
    Affected if The installed version is any version of talkback-secure-linkback-protocol, since no specific version ranges were provided to compare against.
  3. Check if linkback-protocol feature is enabled
    Inspect your application configuration files (XML, YAML, properties) for settings that enable, activate, or configure the linkback-protocol or secure-linkback-protocol component. Look for flags like 'linkback.enabled', 'enableLinkback', or similar.
    Affected if The linkback-protocol feature is explicitly enabled in your configuration.
  4. Review deserialization configuration
    Examine your application's deserialization settings, security policies, or whitelist configurations. Check if untrusted data is being deserialized without strict type filtering.
    Affected if The application deserializes data from external sources without using safe deserialization frameworks or allowlists.

You are affected if the talkback-secure-linkback-protocol library is present in your environment AND the linkback-protocol component is enabled, as this enables the insecure deserialization attack vector.
