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: 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 16 Sep 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: 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 31 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.

Until a fix is available, restrict administrative access to trusted personnel only and monitor for suspicious activity involving API requests.

Description

CVE-2026-76425 is a high-severity SQL injection vulnerability in Cisco Identity Services Engine (ISE) Software APIs. It allows an authenticated attacker with administrative privileges to inject malicious SQL commands due to insufficient validation of input parameters. Exploitation can lead to unauthorized reading of backend database content and server-side request forgery (SSRF) attacks. The affected versions are 3.1.0, 3.2.0, 3.3.0, 3.4.0, and 3.5.0.

Impact

An attacker with administrative access can exploit this vulnerability to read sensitive data from the backend database and perform SSRF attacks, potentially compromising confidentiality and internal network resources. There is no indication of impact on availability. The vulnerability requires valid admin credentials, limiting exploitation to privileged users.

Summary

This vulnerability exists in the APIs of Cisco Identity Services Engine Software where certain parameters are concatenated directly into SQL queries without proper validation. An attacker with valid administrative credentials can send crafted requests containing SQL statements to exploit this flaw. Successful exploitation can result in reading arbitrary data from the backend SQL database and performing SSRF attacks. The CVSS 3.1 base score is 7.6, indicating high severity with network attack vector, low attack complexity, and high impact on confidentiality.
