CVE-2026-47922 Overview
CVE-2026-47922 is a Server-Side Request Forgery (SSRF) vulnerability in Adobe CAI Content Credentials. The flaw allows an attacker to coerce the server into issuing requests to unintended locations, resulting in privilege escalation. Exploitation requires user interaction: a victim must visit a maliciously crafted URL or interact with a compromised web page. The CVSS scope is changed, indicating the impact extends beyond the vulnerable component. Adobe published guidance in security advisory APSB26-111. The weakness maps to CWE-918.
Critical Impact
An attacker can leverage SSRF in CAI Content Credentials to reach otherwise inaccessible internal resources and escalate privileges after tricking a user into visiting a crafted URL.
Affected Products
- Adobe CAI Content Credentials
- Adobe Content Authenticity SDK components referenced in advisory APSB26-111
- Downstream applications embedding the vulnerable CAI Content Credentials functionality

Technical Details for CVE-2026-47922
Vulnerability Analysis
CVE-2026-47922 is a Server-Side Request Forgery (SSRF) issue in Adobe CAI Content Credentials. The vulnerable component accepts a URL or URI as input and issues an outbound request without adequate validation of the target. An attacker can direct the server to internal endpoints, metadata services, or authenticated services the server can reach. Because the CVSS scope is changed, the impact crosses a security boundary, and successful exploitation leads to privilege escalation. The attack vector is network-based and requires user interaction. Confidentiality is not directly impacted, but integrity is affected with low severity.
Root Cause
The root cause is insufficient validation and filtering of user-supplied URLs before the server dereferences them. Classified under [CWE-918], the flaw permits requests to hosts, ports, and schemes that the server should not access on behalf of an untrusted caller. Missing allowlisting of destinations and missing checks for internal or link-local addresses enable the abuse.
Attack Vector
An attacker crafts a URL or a web page that references an attacker-controlled resource. The victim visits the malicious content, which triggers CAI Content Credentials to fetch or process the crafted URL. The server then issues requests to internal services chosen by the attacker. Successful exploitation modifies application state in a way that escalates the attacker's privileges relative to the affected environment.
No verified proof-of-concept code has been published. For technical specifics, see the Adobe Security Advisory APSB26-111.
Detection Methods for CVE-2026-47922
Indicators of Compromise
- Outbound HTTP or HTTPS requests from CAI Content Credentials processes to internal RFC1918 addresses, 127.0.0.1, or cloud metadata endpoints such as 169.254.169.254.
- Unexpected request URIs containing embedded URLs, IP-encoded hosts, or alternate schemes such as file://, gopher://, or dict://.
- Sudden spikes in outbound requests originating from the CAI Content Credentials service to non-standard destinations.
Detection Strategies
- Inspect application and proxy logs for URL parameters that decode to internal hostnames or metadata service IPs.
- Correlate user-initiated web interactions with subsequent server-side fetches to identify SSRF chains.
- Alert on privilege changes or token issuance events that follow anomalous outbound requests from the CAI service account.
Monitoring Recommendations
- Enable egress logging on hosts running CAI Content Credentials and forward the logs to a centralized SIEM.
- Monitor identity systems for privilege escalations tied to service accounts used by CAI Content Credentials.
- Track requests to cloud metadata endpoints from any workload that processes user-supplied URLs.
How to Mitigate CVE-2026-47922
Immediate Actions Required
- Apply the fixed release identified in Adobe Security Advisory APSB26-111 to all instances of CAI Content Credentials.
- Restrict egress from hosts running the vulnerable component so that only required destinations are reachable.
- Block access to cloud metadata services (169.254.169.254) and internal management interfaces from the affected workload.
Patch Information
Adobe published patch guidance in advisory APSB26-111. Administrators should upgrade CAI Content Credentials to the vendor-specified fixed version and validate that the patched build is installed across all instances. Refer to Adobe Security Advisory APSB26-111 for exact version identifiers and download locations.
Workarounds
- Enforce an outbound URL allowlist so that CAI Content Credentials can reach only sanctioned domains.
- Deploy an egress proxy that rejects requests to private IP ranges, link-local addresses, and cloud metadata endpoints.
- Educate users to avoid clicking untrusted links that invoke CAI Content Credentials workflows until patching is complete.
