CVE-2025-64539 — Adobe Experience Manager security vulnerability

Critical CVSS 9.3

Adobe Experience Manager versions 6.5.23 and earlier are affected by a DOM-based Cross-Site Scripting (XSS) vulnerability that could lead to arbitrary code execution. An attacker could exploit this vulnerability by injecting malicious scripts into a web page that are executed in the context of the victim's browser. A successful attacker can abuse this to achieve session takeover, increasing the confidentiality and integrity impact as high. Exploitation of this issue requires user interaction in that a victim must visit a crafted malicious page.

Matched remediation archetype

Cross-site scripting and unsafe browser output

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace reflected, stored, and DOM-derived untrusted values into HTML, attributes, URLs, styles, scripts, and client-side template sinks.
  • Identify affected origins, authenticated user roles, sensitive browser capabilities, and where content is shared across tenants.
  • Review framework escaping, rich-text sanitization, legacy templates, and client-side rendering paths.

Remediate safely

  • Use context-aware framework output encoding and safe DOM APIs; keep untrusted data out of executable contexts.
  • Sanitize intentionally supported markup with a maintained allowlist policy and validate URLs and attributes separately.
  • Update affected rendering components and add tests for every output context using inert sentinel markup.
