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.

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 26 Oct 2026.

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 or the CVSS exploit maturity 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

Immediately audit all Adobe Experience Manager instances to identify versions 6.5.23 or earlier and prioritize their upgrade to the latest patched version once available.
Implement strict input validation and sanitization on all form fields to prevent malicious script injection.
Deploy Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers.
Limit user privileges on form inputs, ensuring that only trusted users can submit data to sensitive fields.
Monitor web application logs for unusual input patterns or repeated attempts to inject scripts.
Educate users about the risks of clicking on suspicious links or visiting untrusted pages within the organization’s web environment.
Use web application firewalls (WAFs) with rules designed to detect and block XSS payloads targeting AEM.
Prepare incident response plans to quickly address any exploitation attempts or breaches related to this vulnerability.

Description

CVE-2025-64845 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 browser of users who visit the affected page. This vulnerability requires user interaction to trigger and can lead to partial compromise of confidentiality and integrity but does not impact availability. The CVSS score is 5.4 (medium severity), reflecting the moderate risk due to the need for user interaction and limited scope of impact. No known exploits are currently reported in the wild. European organizations using AEM for content management and web delivery should prioritize patching or mitigating this vulnerability to prevent potential data theft or session hijacking. Countries with high adoption of Adobe Experience Manager, such as Germany, France, and the UK, are more likely to be affected.

Impact

For European organizations, this vulnerability can lead to unauthorized disclosure of sensitive information such as session tokens or personal data, enabling further attacks like session hijacking or privilege escalation. The integrity of web content can be compromised, potentially damaging organizational reputation and user trust. While availability is not directly impacted, the indirect effects of compromised user sessions or data leakage can disrupt business operations. Organizations using AEM for public-facing websites or intranet portals are particularly at risk, as attackers can exploit the vulnerability to target employees or customers. The medium severity score reflects a moderate risk, but the widespread use of Adobe Experience Manager in Europe increases the potential impact. Regulatory frameworks such as GDPR heighten the consequences of data breaches resulting from such vulnerabilities, potentially leading to legal and financial penalties.

Architecture and Design · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
Implementation · Architecture and Design
Understand the context in which your data will be used and the encoding that will be expected. This is especially important when transmitting data between different components, or when generating outputs that can contain multiple encodings at the same time, such as web pages or multi-part mail messages.
