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: High: A successful attack depends on conditions beyond the attacker's control. That is, a successful attack cannot be accomplished at will, but requires the attacker to invest in some measurable amount of effort in preparation or execution against the vulnerable component before a successful attack can be expected. For example, a successful attack may require an attacker to: gather knowledge about the environment in which the vulnerable target/component exists; prepare the target environment to improve exploit reliability; or inject themselves into the logical network path between the target and the resource requested by the victim in order to read and/or modify network communications (e.g., a man in the middle attack).
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: 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: 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 20 Jan 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
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 2026-10-25.

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. Monitor IBM security advisories closely and apply official patches or updates as soon as they become available to address the heap clearing flaw. 2. Until patches are released, restrict network access to IBM Concert services using firewalls and network segmentation to limit exposure to trusted internal users only. 3. Implement strict access controls and logging on systems running IBM Concert to detect and respond to suspicious remote access attempts. 4. Conduct memory analysis and forensic reviews on affected systems to identify potential data leakage or compromise. 5. Employ application-layer protections such as Web Application Firewalls (WAFs) to detect anomalous requests targeting IBM Concert. 6. Educate development and operations teams on secure memory management practices to prevent similar vulnerabilities in custom integrations or extensions. 7. Regularly audit and review configurations to ensure no unnecessary services or ports are exposed externally. 8. Consider deploying intrusion detection/prevention systems (IDS/IPS) tuned to detect exploitation attempts related to heap memory vulnerabilities. 9. Maintain an incident response plan that includes procedures for handling data leakage incidents involving IBM Concert. 10. Evaluate alternative collaboration tools if IBM Concert cannot be secured promptly, especially in high-risk environments.

Description

IBM Concert 1.0.0 through 2.1.0 could allow a remote attacker to obtain sensitive information from allocated memory due to improper clearing of heap memory.

Impact

For European organizations, the primary impact is unauthorized disclosure of sensitive information, which could include credentials, personal data, or proprietary business information residing temporarily in heap memory. This breach of confidentiality could facilitate further attacks such as privilege escalation, lateral movement, or data exfiltration. Sectors handling sensitive or regulated data, such as finance, healthcare, and government, are particularly at risk. The vulnerability does not affect system integrity or availability, so operational disruption is unlikely. However, the exposure of confidential data can lead to compliance violations under GDPR and other data protection laws, resulting in legal and financial penalties. The remote exploitability without authentication increases the risk profile, especially for organizations with exposed IBM Concert services. The medium CVSS score reflects a balance between the high impact on confidentiality and the high attack complexity, meaning exploitation is possible but not trivial. Organizations lacking robust network segmentation or monitoring may face increased risk. Overall, the vulnerability could undermine trust in IBM Concert deployments and necessitate urgent remediation to protect sensitive European data assets.

Variant weakness
Using realloc() to resize buffers that store sensitive information can leave the sensitive information exposed to attack, because it is not removed from memory.
