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: 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: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 9 Mar 2026
Detectable: no evidence on record.
No public nuclei template indexed

Exploited in the wildExploited: no evidence on record.

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

To mitigate CVE-2025-70040, organizations should immediately audit their logging configurations in LupinLin1 jimeng-web-mcp v2.1.2 and related systems. Sensitive information must be excluded from logs or masked using techniques such as redaction or encryption before logging. Access to log files should be strictly controlled using file system permissions and network segmentation to prevent unauthorized access. Implement monitoring and alerting for unusual log access patterns. If possible, upgrade to a patched version once available or apply vendor-provided fixes. Additionally, conduct code reviews to ensure secure logging practices are followed, avoiding logging of sensitive data like passwords, tokens, or personal identifiers. Employ centralized logging solutions with strong access controls and encryption at rest and in transit. Train developers and administrators on secure logging standards and the risks of sensitive data exposure. Finally, consider implementing data loss prevention (DLP) tools to detect sensitive information in logs.

Description

An issue pertaining to CWE-532: Insertion of Sensitive Information into Log File was discovered in LupinLin1 jimeng-web-mcp v2.1.2. This allows an attacker to obtain sensitive information.

Impact

The primary impact of CVE-2025-70040 is the potential exposure of sensitive information through log files. Organizations using the affected software risk confidentiality breaches if attackers access these logs. This can lead to credential theft, unauthorized system access, privacy violations, and compliance failures with data protection regulations. The integrity and availability of systems are less directly impacted, but the loss of confidentiality can facilitate further attacks such as privilege escalation or lateral movement within networks. Since exploitation does not require authentication, the attack surface is broad, especially if logs are stored on shared or poorly secured systems. The absence of known exploits suggests limited current impact, but the vulnerability could become a vector for attackers once widely known. Organizations in sectors handling sensitive or regulated data are particularly at risk, as exposure could result in financial loss, reputational damage, and legal consequences.
