Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
Confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Detectable: no evidence on record.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-26.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

To mitigate CVE-2025-64627 effectively, organizations should implement a multi-layered approach beyond generic advice. First, apply strict input validation on all form fields to ensure that only expected data types and formats are accepted, rejecting or sanitizing any suspicious input. Second, implement robust output encoding or escaping mechanisms on all user-supplied content before rendering it in the browser to prevent script execution. Third, employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of any injected code. Fourth, restrict the use of vulnerable form fields or disable them if not essential, minimizing the attack surface. Fifth, monitor web application logs and user activity for unusual patterns indicative of attempted exploitation. Sixth, educate users and administrators about the risks of XSS and encourage cautious behavior when interacting with web content. Finally, stay alert for official Adobe patches or updates addressing this vulnerability and deploy them promptly once available. If immediate patching is not possible, consider implementing web application firewalls (WAFs) with custom rules to detect and block malicious payloads targeting the vulnerable fields. Regular security assessments and penetration testing focused on XSS vulnerabilities can help identify and remediate similar issues proactively.

Description

CVE-2025-64627 is a stored Cross-Site Scripting (XSS) vulnerability affecting Adobe Experience Manager (AEM) versions 6.5.23 and earlier. A low privileged attacker can inject malicious JavaScript into vulnerable form fields, which executes in the browsers of users who visit the affected pages. This vulnerability requires user interaction to trigger and does not allow direct system compromise but can lead to session hijacking, data theft, or further attacks within the context of the victim's browser. The CVSS score is 5.4 (medium severity), reflecting the moderate impact and ease of exploitation with low privileges. No known exploits are currently in the wild, and no patches have been linked yet. European organizations using AEM, especially in countries with high adoption of Adobe products in government, media, and enterprise sectors, should prioritize mitigation. Mitigations include input validation, output encoding, and restricting form field usage, along with monitoring and applying updates once available.

Impact

For European organizations, the impact of CVE-2025-64627 can be significant, especially for those using Adobe Experience Manager to manage public-facing websites, intranets, or digital services. Successful exploitation could lead to unauthorized disclosure of sensitive information such as session tokens, user credentials, or personal data, potentially violating GDPR and other data protection regulations. This could result in reputational damage, regulatory fines, and loss of customer trust. Additionally, attackers could leverage the XSS vulnerability to perform phishing attacks, deliver malware, or escalate privileges within the affected environment. The medium severity rating reflects that while the vulnerability does not directly compromise system availability or allow remote code execution, the confidentiality and integrity of user sessions and data are at risk. Organizations in sectors such as government, finance, healthcare, and media, which often use AEM for content management, may face higher risks due to the sensitivity of the data handled. The requirement for user interaction means that social engineering or targeted campaigns could increase the likelihood of successful exploitation. Furthermore, the persistent nature of stored XSS means that multiple users could be affected over time if the vulnerability is not remediated.
