CAI Content Credentials is affected by an Integer Underflow (Wrap or Wraparound) vulnerability that could result in an application denial-of-service. An attacker could exploit this vulnerability to crash the application, leading to a denial-of-service condition. Exploitation of this issue does not require user interaction.
AnalysisAI
Integer underflow (CWE-191) in Adobe's Content Credentials ecosystem - covering the Rust SDK (c2pa), JavaScript SDK (@contentauth/c2pa-web), and CLI tool (c2patool) - allows a local attacker to crash any application that processes a specially crafted content credential payload, producing a denial-of-service condition. All three components share the underlying parsing logic and are affected up to their respective patch releases. …

Vulnerability AssessmentAI
| Exploitation | The attack vector is local (AV:L): a crafted content credential payload must be supplied to and processed by an application using the vulnerable SDK or CLI tool on the target host. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 6.2 with vector AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H accurately captures the constrained but straightforward nature of this flaw. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Vendor-released patches are available for all three affected components. … Detailed patch versions, workarounds, and compensating controls in full report. |
