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: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
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: 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.

Exploitation evidence

Disclosed: evidence found.
CVE published 17 Feb 2026
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

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 2026-10-25.

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. Implement strict session management policies, including reducing session timeout durations and enforcing immediate session invalidation upon logout or expiration. 2. Monitor and log session activities to detect anomalous reuse of expired session tokens or unusual user impersonation patterns. 3. Restrict access to QRadar EDR consoles to trusted networks and enforce multi-factor authentication (MFA) to reduce the risk of compromised credentials. 4. Apply network segmentation to isolate QRadar EDR components from general user networks, limiting lateral movement opportunities. 5. Regularly review and audit user privileges to minimize the number of accounts with elevated access. 6. Stay informed on IBM’s security advisories and apply patches promptly once released. 7. Consider deploying web application firewalls (WAFs) or session management proxies that can enforce session expiration policies externally as a temporary control.

Description

IBM Security QRadar EDR 3.12 through 3.12.23 does not invalidate session after a session expiration which could allow an authenticated user to impersonate another user on the system.

Impact

For European organizations, this vulnerability poses a risk to the security and trustworthiness of their endpoint detection and response infrastructure. Successful exploitation could allow malicious insiders or compromised accounts to impersonate other users, potentially escalating privileges or accessing sensitive security telemetry and configurations. This could undermine incident detection, delay response efforts, or facilitate further attacks such as data exfiltration or ransomware deployment. Critical sectors like finance, energy, telecommunications, and government agencies that rely heavily on IBM QRadar EDR for threat detection are particularly vulnerable. The medium severity indicates a moderate but tangible risk that could impact confidentiality, integrity, and availability of security operations. The lack of known exploits reduces immediate risk but does not eliminate the threat, especially in targeted attacks.
