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: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
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: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 17 Feb 2026
Detectable: no evidence on record.
No public nuclei template indexed

Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

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 this vulnerability, organizations should prioritize applying any available patches or updates from IBM as soon as they are released. In the absence of patches, implementing anti-CSRF tokens in all state-changing requests within IBM Concert can prevent unauthorized request execution. Additionally, organizations should enforce strict SameSite cookie attributes to limit cross-origin request capabilities. Employing web application firewalls (WAFs) with custom rules to detect and block suspicious CSRF attack patterns can provide an additional layer of defense. User education is critical; training users to recognize phishing attempts and avoid clicking on untrusted links reduces the risk of exploitation. Network segmentation and limiting access to IBM Concert interfaces to trusted networks or VPNs can reduce exposure. Regular security assessments and penetration testing focused on web application vulnerabilities will help identify and remediate similar issues proactively.

Description

IBM Concert 1.0.0 through 2.1.0 for Z hub component is vulnerable to cross-site request forgery which could allow an attacker to execute malicious and unauthorized actions transmitted from a user that the website trusts.

Impact

The primary impact of this vulnerability is on the integrity of the IBM Concert application and its data. An attacker exploiting this CSRF flaw can cause users to unknowingly perform unauthorized actions, such as modifying configurations, changing workflows, or triggering operations that could disrupt business processes or lead to data corruption. Although confidentiality and availability are not directly affected, the integrity compromise can have cascading effects, including operational disruptions and potential compliance violations. Organizations relying on IBM Concert for critical workflows or sensitive operations may face increased risk of unauthorized changes that could undermine trust in their systems. Since the vulnerability requires user interaction, the risk is somewhat mitigated by user awareness, but phishing or social engineering campaigns could increase exploitation likelihood. The lack of known exploits in the wild suggests limited current threat activity, but the vulnerability remains a significant concern for organizations with exposed IBM Concert deployments.

Compound weaknessLikelihood of exploit: MediumCWE Top 25 (2025): #3OWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor.
Architecture and Design · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
Implementation
Ensure that the application is free of cross-site scripting issues (CWE-79), because most CSRF defenses can be bypassed using attacker-controlled script.
Architecture and Design
Generate a unique nonce for each form, place the nonce into the form, and verify the nonce upon receipt of the form. Be sure that the nonce is not predictable (CWE-330).
