Threat metrics

Exploit Maturity: POC

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

Attack Vector: Network: The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, 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: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: Low: The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
User Interaction: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system 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 Vulnerable System.
Vulnerable system integrity: None: There is no loss of integrity within the Vulnerable System.
Vulnerable system availability: None: There is no impact to availability within the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.
Exploit Maturity: POC: Based on threat intelligence sources each of the following must apply: · Proof-of-concept is publicly available · No knowledge of reported attempts to exploit this vulnerability · No knowledge of publicly available solutions used to simplify attempts to exploit the vulnerability

Definitions: FIRST CVSS v4.0 specification.

Exploitation evidence

Disclosed: evidence found.
CVE published 8 Oct 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
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
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 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

1. Apply the official patch identified by commit b15e29021d326be127193a5dbbd528c4e37e6324 immediately to all affected OpnForm instances. 2. Conduct a thorough audit of access control configurations related to the /edit functionality and other sensitive endpoints to ensure proper enforcement of authorization policies. 3. Implement network-level restrictions such as IP whitelisting or VPN access to limit exposure of the OpnForm interface to trusted users only. 4. Monitor logs for unusual access patterns or attempts to exploit the /edit endpoint, enabling early detection of exploitation attempts. 5. Review and enhance application-level authentication and authorization mechanisms, potentially adding multi-factor authentication for administrative functions. 6. Educate development and operations teams about secure coding and configuration practices to prevent similar access control issues in future releases. 7. Maintain an incident response plan to quickly address any exploitation attempts or breaches related to this vulnerability.

Description

A vulnerability was determined in JhumanJ OpnForm up to 1.9.3. Impacted is an unknown function of the file /edit. Executing manipulation can lead to improper access controls. The attack can be executed remotely. The exploit has been publicly disclosed and may be utilized. This patch is called b15e29021d326be127193a5dbbd528c4e37e6324. Applying a patch is advised to resolve this issue.

Impact

For European organizations, this vulnerability poses a moderate risk of unauthorized access to sensitive data or functionality within applications using JhumanJ OpnForm. Given the remote exploitability without authentication, attackers could leverage this flaw to bypass security controls, potentially leading to data leakage or unauthorized modifications. While the CVSS score suggests limited impact on integrity and availability, the confidentiality breach alone can have serious consequences, especially for sectors handling personal data under GDPR, such as healthcare, finance, and government services. Exploitation could undermine trust, lead to regulatory penalties, and cause operational disruptions if sensitive workflows are accessed or altered. The absence of known exploits reduces immediate threat but does not eliminate risk, particularly as attackers may develop exploits following public disclosure. European entities relying on OpnForm for form management or data collection should consider this vulnerability a priority for remediation to maintain compliance and security posture.
