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: 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: 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: 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: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the impacted component are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to 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.

What to do

AI-suggested

Upgrade inducer relate to version 2024.1 or later as soon as the patch is released to ensure the vulnerability is addressed.
If you cannot patch yet, restrict access to the Markup Sandbox feature to trusted users only, minimizing exposure to untrusted inputs.
Implement strict input validation and sanitization on all data passed to template rendering components to prevent injection of malicious payloads.
Employ runtime application self-protection (RASP) or web application firewalls (WAF) with custom rules to detect and block suspicious template injection patterns.
Monitor logs for unusual template rendering errors or unexpected code execution attempts.
Conduct regular privilege audits to limit the number of users with high-level access required to exploit this vulnerability.
Use containerization or sandboxing at the OS level to isolate the application environment, reducing the impact of potential code execution.

Description

Server-Side Template Injection (SSTI) vulnerability in inducer relate before v.2024.1, allows remote attackers to execute arbitrary code via a crafted payload to the Markup Sandbox feature.

Impact

The primary impact of this vulnerability is unauthorized remote code execution on servers running vulnerable versions of inducer relate. This can lead to the exposure of sensitive data (high confidentiality impact), partial modification of data (low integrity impact), and limited disruption of service (low availability impact). Organizations relying on inducer relate for data processing or research could face data breaches, loss of intellectual property, or compromised system integrity. Since exploitation requires high privileges, the threat is more severe in environments where attackers can gain elevated access, such as through compromised credentials or insider threats. The vulnerability could be leveraged as a foothold for further lateral movement within networks, increasing the overall risk. Although no known exploits exist currently, the medium severity and remote exploitability warrant timely remediation to prevent potential attacks.

The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment.
Architecture and Design · Refactoring
Refactor your program so that you do not have to dynamically generate code.
Architecture and Design
Run your code in a "jail" or similar sandbox environment that enforces strict boundaries between the process and the operating system. This may effectively restrict which code can be executed by your product.
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.
