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: High: The attacker is authorized with (i.e., requires) privileges that provide significant (e.g., administrative) control over the vulnerable component that could affect component-wide settings and files.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
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: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: None: There is no loss of integrity within 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 30 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.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), 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

Monitor Adobe’s official channels for patches addressing CVE-2026-21360 and apply them promptly once available.
Restrict and audit high-privileged user accounts to minimize the risk of misuse or compromise, employing the principle of least privilege.
Implement strict access controls and file system permissions to limit the ability of any user or process to access sensitive directories outside their scope.
Use web application firewalls (WAFs) with custom rules to detect and block path traversal patterns in requests.
Conduct regular security audits and code reviews focusing on input validation and path handling logic within Adobe Commerce customizations.
Employ runtime application self-protection (RASP) tools to detect anomalous file access attempts.
Maintain comprehensive logging and monitoring to detect suspicious activities related to file access.
Consider network segmentation to isolate critical systems and reduce the impact of compromised high-privileged accounts. These steps go beyond generic advice by focusing on privilege management, proactive detection, and layered defenses tailored to the nature of this vulnerability.

Description

Adobe Commerce versions 2.4.9-alpha3, 2.4.8-p3, 2.4.7-p8, 2.4.6-p13, 2.4.5-p15, 2.4.4-p16 and earlier are affected by an Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability that could result in a security feature bypass. A high-privileged attacker could leverage this vulnerability to access unauthorized files or directories outside the intended restricted path. Exploitation of this issue does not require user interaction.

Impact

The primary impact of CVE-2026-21360 is the potential unauthorized disclosure of sensitive files and data due to path traversal outside restricted directories. This compromises confidentiality, as attackers can access configuration files, credentials, or other sensitive information stored on the server. While integrity and availability are not directly affected, the exposure of sensitive data can facilitate further attacks, including privilege escalation or lateral movement within the network. Organizations running affected Adobe Commerce versions risk data breaches that could lead to financial loss, reputational damage, and regulatory penalties, especially in sectors handling personal or payment information. The requirement for high privileges limits the attack surface to insiders or attackers who have already compromised accounts with elevated rights, but the lack of user interaction and network-based exploitability increases risk. Given Adobe Commerce's widespread use in global e-commerce, the vulnerability could impact a broad range of organizations, from small retailers to large enterprises.

Base weaknessLikelihood of exploit: HighCWE Top 25 (2025): #6OWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
Implementation · Input Validation
Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
Architecture and Design
For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks…
Implementation · Input Validation
Inputs should be decoded and canonicalized to the application's current internal representation before being validated (CWE-180). Make sure that the application does not decode the same input twice (CWE-174).
