What to check
- Applies to
- The 6 CVEs named below. Whether you run an affected version is not assessed: check the versions the source lists.
- Exploitation
- No exploitation in the wild and no public exploit is recorded for the CVEs named.
The Dutch National Cyber Security Centre (NCSC-NL) issued an advisory summarizing six vulnerabilities patched by Adobe in Experience Manager (AEM) Forms on Java Enterprise Edition, affecting AEM 6.5 Forms and AEM 6.5 LTS Forms. All six flaws are rated critical and span multiple vulnerability classes: improper authorization, insufficient input validation, Server-Side Request Forgery (SSRF), Cross-Site Scripting (XSS), and Cross-Site Request Forgery (CSRF).
Two of the six vulnerabilities can be exploited remotely without authentication. The most severe, CVE-2026-75745, carries a CVSS score of 10.0 (NCSC lists 9.8 in the body text, 10.0 in the reference table) and allows unauthenticated, no-interaction remote code execution. Successful exploitation across the set of flaws could result in arbitrary code execution, privilege escalation, and bypass of security controls. Adobe states it is not aware of any active exploitation in the wild.
Defenders running AEM 6.5 Forms or AEM 6.5 LTS Forms on JEE should prioritize applying Adobe's security updates, particularly given the unauthenticated RCE vector. As this is a Java EE deployment often exposed for form processing and document generation, organizations should verify patch status across all instances and review external exposure of AEM Forms endpoints as an interim mitigation while patching is completed.

What this brief leaves out
This page is the free tier: the write-up, the severity, the names. In the app the same report carries live profiles of the CVEs it names. The paid plans add the security research and news reporting the free tier leaves out.
It sits in a corpus of 16,436 reports from 149 sources, 661 of them written in the last seven days, and it grows through the day.
A new account starts with three days of all of it, no card, then keeps the government and CERT reporting free. Slack alerts are a paid-plan feature: name the vendors you run and Slack hears about the reports that touch them, not the rest of the week's. Nothing is charged unless you subscribe.
