CVE-2026-47904
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 · uneditedCAI Content Credentials versions [email protected], c2pa-v0.80.1 and earlier are affected by an Uncontrolled Resource Consumption vulnerability. An attacker could exploit this vulnerability to exhaust system resources, resulting in an application denial-of-service condition. Exploitation of this issue does not require user interaction.
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 c2pa-web and c2pa-v libraries used for Content Credentials contain an uncontrolled resource consumption vulnerability. An attacker can trigger excessive resource usage (likely through malicious or crafted Content Credentials data) without any user interaction, leading to denial of service.

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 c2pa-web package usageRun 'npm list c2pa-web' or check package.json dependencies for c2pa-web entry and note the version numberAffected if The installed version is 0.7.1 or lower
-
Identify c2pa-v package usageRun 'npm list c2pa-v' or check package.json dependencies for c2pa-v entry and note the version numberAffected if The installed version is 0.80.1 or lower
-
Scan for library presence in projectSearch project files and node_modules for 'c2pa-web' or 'c2pa-v' directories or files using 'find . -name "*c2pa*"'Affected if Either library is present and no version or version is within affected ranges
-
Check application runtime dependenciesRun 'pip list | grep -i c2pa' or 'npm ls c2pa-web c2pa-v' to list all c2pa-related packages and their versionsAffected if Any c2pa package version matches or is below the affected thresholds
The environment is affected if c2pa-web version 0.7.1 or lower, or c2pa-v version 0.80.1 or lower, is present and processing external input.

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 dataUpgrade to patched versions of c2pa-web (after 0.7.1) and c2pa-v (after v0.80.1). Review application integration points where Content Credentials are processed to ensure proper resource limits are in place.
