Adobe Content Credentials EUVD-2026-100724

Exploitation requires that the target application or service embeds and exposes the Adobe CAI Content Credentials SDK to attacker-supplied input, and that this input reaches the validation routine affected by CWE-20; per the CVSS vector (AV:N/AC:L/PR:N/UI:N) no authentication, no user interaction, and no special configuration are stated as prerequisites, so a reachable integration processing untrusted content is the key condition. The primary limiting factor is deployment context: the SDK must be integrated into a network-reachable code path that handles untrusted/externally-supplied content, so environments that only process trusted, internally-generated content have reduced realistic exposure. Impact is bounded to unauthorized write/integrity (C:N/A:N) - there is no confidentiality disclosure or availability loss.

This is a medium-to-high severity integrity flaw (CVSS 7.5, I:H only) in the Adobe CAI Content Credentials SDK, confirmed and scored by Adobe PSIRT. The CVSS vector (AV:N/AC:L/PR:N/UI:N) indicates a network-reachable, low-complexity, unauthenticated bypass requiring no user interaction, which on paper is attractive to attackers; however, the impact is strictly to integrity (C:N/A:N), meaning the realistic outcome is unauthorized write/modification - most plausibly forging or tampering with content provenance/credential data - rather than data theft or service disruption. No EPSS score, CISA KEV listing, or public POC was provided in the input, so there is currently no public exploit identified at time of analysis and no evidence of active exploitation; this means the network/no-auth metrics describe theoretical ease, not demonstrated real-world attack activity. The 'Authentication Bypass' tag conflicts somewhat with the description, which characterizes the issue as a 'Security feature bypass' via improper input validation (CWE-20) - verify the precise bypass class with Adobe's advisory. Net: a credible priority for teams that embed this SDK, but the absence of KEV/EPSS/POC signals and the integrity-only impact suggest it is a patch-on-normal-cycle issue rather than an emergency, absent evidence it processes untrusted input in an internet-facing path.

An attacker sends crafted, malformed input to a service or application that embeds the CAI Content Credentials SDK, where improper input validation allows the attacker to bypass a security check without authenticating or any user interaction. This grants unauthorized write access, which could be used to inject or alter content credential/provenance data so that tampered media appears validly signed. No public proof-of-concept was identified at time of analysis.
