Impact

This CVE describes a stored cross‑site scripting vulnerability in Adobe Experience Manager that could be abused by a low‑privileged attacker to inject malicious scripts into vulnerable form fields. When a victim navigates to the page containing the stored input, the malicious JavaScript executes in the victim’s browser, enabling possible session hijacking, credential theft, or defacement. Scope is changed as the vulnerability allows the attacker to affect other users who view the compromised content.

Affected Systems

The vulnerability affects Adobe Experience Manager 6.5, Adobe Experience Manager 6.5 LTS, and Adobe Experience Manager as a Cloud Service. These versions should be reviewed for the presence of the issue.

Risk and Exploitability

The CVSS score of 5.4 indicates a medium‑severity risk. EPSS is not available, and the vulnerability is not listed in CISA’s KEV catalog, implying no known widespread exploitation at the time of assessment. The attack vector is likely remote, via the software’s form capabilities; a low‑privileged contributor can exploit the flaw, and any user who views the populated page may be impacted. Given the stored nature of the payload, the risk is amplified by the persistence of the malicious script across sessions and users.

OpenCVE Recommended Actions

  • Apply the Adobe security patch that addresses CVE-2026-75733 for the version of Adobe Experience Manager you are running.
  • If a patch is not yet available, restrict editing capabilities on the vulnerable form fields or deny write access to untrusted contributors.
  • Sanitise or escape all user‑supplied input before storing it in the form field to remove potential script tags or JavaScript injection vectors.
  • Consider deploying a Web Application Firewall rule to detect and block common XSS payloads.
