Adobe Experience Manager versions 6.5.23 and earlier are affected by a stored Cross‑Site Scripting (XSS) vulnerability that could be abused by a low‑privileged attacker to inject malicious scripts into vulnerable form fields. Malicious JavaScript may be executed in a victim’s browser when they browse to the page containing the vulnerable field, allowing the attacker to run arbitrary client‑side code in the user’s context.

The affected product is Adobe Experience Manager. All installations running version 6.5.23 or any earlier release are vulnerable, as indicated by the vendor advisory and supported by the CPE entries for 6.5 and its LTS service packs.

The CVSS score of 5.4 reflects moderate severity, and the EPSS score of less than 1% indicates a low likelihood of exploitation. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog. The attack vector is explicitly described as low‑privileged submission of malicious content through vulnerable form fields, which results in client‑side script execution in the victim’s browser.
