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 Adobe C2pa library versionCheck the installed version of the Adobe C2pa library in your project dependencies (e.g., package.json, Cargo.toml, or similar dependency manifest). If using a package manager, run a command like 'npm list c2pa' or the equivalent for your language ecosystem.Affected if The installed version is 0.84.0 or lower
-
Identify Adobe C2pa Web versionCheck the installed version of the Adobe C2pa Web package in your web project dependencies. This may appear in your package.json, requirements.txt, or similar dependency file.Affected if The installed version is 0.7.0 or lower
-
Identify Adobe C2patool versionRun the c2patool command with a version flag, typically 'c2patool --version' or check the binary/package version through your system's package manager if installed system-wide.Affected if The installed version is 0.17.0 or lower
-
Confirm write operations are enabledReview your application configuration to determine if write operations (such as creating or modifying Content Credentials) are enabled. Check for configuration flags or settings that control whether the affected component can write data to the system.Affected if Write operations are enabled and the installed version of any affected product is within the vulnerable range
You are affected if any of the three Adobe C2pa components are installed at or below their respective vulnerable version thresholds AND write operations are enabled in your 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 dataImplement proper input validation and sanitization at all input points where write operations are processed to ensure only authorized, properly formatted data can be written.
