DescriptionCVE.org

CAI Content Credentials versions 0.78.2, 0.7.0 and earlier are affected by an Uncontrolled Resource Consumption vulnerability that could lead to application denial-of-service. 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.

AnalysisAI

Uncontrolled resource consumption in Adobe CAI Content Credentials SDK (versions 0.7.0 and earlier, and 0.78.2) allows a local attacker without authentication to exhaust system resources, causing application-level denial of service. Rooted in CWE-400, the SDK imposes no sufficient limits on resource consumption when processing input, with the entire impact confined to availability - no confidentiality or integrity exposure exists. No public exploit code has been identified, EPSS sits at 0.01% (0th percentile), SSVC characterizes exploitation as 'none', and the vulnerability is absent from CISA's KEV catalog, collectively indicating low real-world exploitation probability at time of analysis.

Technical ContextAI

Adobe CAI Content Credentials is the vendor's implementation of the Content Authenticity Initiative (C2PA) SDK, used to embed and verify digital provenance metadata in media assets such as images and video. The root cause class is CWE-400 (Uncontrolled Resource Consumption), where the SDK fails to impose runtime bounds on memory or CPU usage during input processing - a common consequence of missing algorithmic safeguards or absent input validation gates. The CPE identifier cpe:2.3:a:adobe:cai_content_credentials:*:*:*:*:*:*:*:* confirms this is an Adobe application-layer library rather than an OS or infrastructure component. When a local process supplies specially crafted credential manifests or oversized input payloads, the SDK enters unbounded consumption loops, ultimately starving the hosting application of resources and producing a denial-of-service condition.

RemediationAI

Upgrade Adobe CAI Content Credentials to a fixed version as detailed in Adobe Security Bulletin APSB26-53, available at https://helpx.adobe.com/security/products/content-authenticity-sdk/apsb26-53.html. No specific patched version number is independently confirmed from the available data outside the vendor advisory; that bulletin must be consulted for the exact target release. While awaiting patching, restrict local user and process access on systems running the SDK - only trusted processes should be permitted to supply input to the SDK, which directly eliminates the PR:N exploitation path. Imposing application-layer input size or rate limits where configurable can partially mitigate resource exhaustion but may affect normal SDK functionality, particularly for large media assets. Monitoring for anomalous CPU or memory consumption on SDK-hosting systems provides an operational detection signal without service disruption.
