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: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: None: There is no loss of confidentiality within 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.

Exploitation evidence

Disclosed: evidence found.
CVE published 4 Nov 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

No attack traffic recorded by OffSeq Mirage sensors

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 upgrade Mulesoft Anypoint Code Builder to version 1.12.1 or later, as recommended by Salesforce.
Implement strict file system permissions to restrict write access to configuration files only to authorized administrators and processes.
Employ configuration file integrity monitoring tools to detect unauthorized changes in real-time.
Use network segmentation and firewall rules to limit exposure of Mulesoft services to trusted networks and users only.
Conduct regular audits of user permissions and access controls within the Mulesoft environment to ensure least privilege principles are enforced.
Integrate logging and alerting mechanisms for configuration changes to enable rapid incident response.
Educate development and operations teams about the risks of improper permission assignments and secure configuration management practices.
Review and harden CI/CD pipelines that interact with Mulesoft configurations to prevent injection of malicious configurations. These steps go beyond generic patching by focusing on operational security hygiene and proactive detection.

Description

Incorrect Permission Assignment for Critical Resource vulnerability in Salesforce Mulesoft Anypoint Code Builder allows Manipulating Writeable Configuration Files.This issue affects Mulesoft Anypoint Code Builder: before 1.12.1

Impact

For European organizations, this vulnerability poses a moderate risk primarily to the integrity of their integration and API management workflows. Manipulation of writable configuration files could lead to unauthorized changes in deployment settings, potentially causing misrouted data flows, introduction of malicious payloads, or disruption of business-critical integrations. This can affect sectors heavily reliant on digital transformation and API ecosystems, such as finance, telecommunications, and manufacturing. While confidentiality and availability are not directly impacted, integrity compromises can lead to indirect data breaches or service interruptions if attackers leverage altered configurations to escalate privileges or inject malicious code. The lack of authentication requirement increases the attack surface, especially for organizations exposing Mulesoft services to the internet. Given Salesforce's strong presence in Europe, especially in countries with large enterprise IT sectors, the threat could affect a wide range of industries. However, the absence of known exploits in the wild suggests that immediate risk is moderate, but proactive mitigation is essential to prevent potential exploitation.

CWE-732Incorrect Permission Assignment for Critical Resource (opens in a new tab)
Class weaknessLikelihood of exploit: HighOWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The product specifies permissions for a security-critical resource in a way that allows that resource to be read or modified by unintended actors.
Implementation
When using a critical resource such as a configuration file, check to see if the resource has insecure permissions (such as being modifiable by any regular user), and generate an error or even exit the software if there is a possibility that the resource could have been modified by an unauthorized party.
Architecture and Design
Divide the software into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully defining distinct user groups, privileges, and/or roles. Map these against data, functionality, and the related resources. Then set the permissions accordingly.
Architecture and Design · Operation · Sandbox or Jail
Run the code in a "jail" or similar sandbox environment that enforces strict boundaries between the process and the operating system. This may effectively restrict which files can be accessed in a particular directory or which commands can be executed by the software.
