- Exploitation
- No exploitation in the wild and no public exploit is recorded for the CVEs named.
NCSC-NL published an advisory summarizing Adobe's patches for multiple vulnerabilities in Adobe Experience Manager (AEM). The most severe issues (CVSS 9.9) involve improper control of code generation mechanisms, enabling a low-privileged attacker to execute arbitrary code and escalate privileges without any user interaction. Additional flaws include stored, reflected, and DOM-based Cross-Site Scripting (XSS) vulnerabilities that allow injection and execution of malicious JavaScript in a victim's browser, as well as incorrect authorization checks permitting unauthorized code execution and an input validation weakness that could allow security mechanism bypass.
Exploitation of these vulnerabilities could result in unauthorized code execution, privilege escalation, and unauthorized access to data or functionality within AEM deployments. No in-the-wild exploitation is mentioned in the advisory. Adobe has released updates addressing all listed CVEs; affected organizations running AEM should apply the vendor patches promptly, prioritizing the CVSS 9.9-rated code injection and privilege escalation issues.
This is a routine vendor patch advisory relayed by NCSC-NL with no indication of active exploitation, proof-of-concept availability, or threat actor involvement. Defenders should treat this as a patch-management action item, verifying AEM instances are updated to the fixed versions referenced in Adobe's own security bulletin.

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 16,433 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.
