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: 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: 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 26 Mar 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 30 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.

AI-suggested

Implement immediate session invalidation upon password changes to ensure all active sessions are terminated.
Enforce short session lifetimes and require re-authentication for sensitive operations.
Monitor active sessions for unusual activity and implement anomaly detection to identify potential session hijacking.
Use multi-factor authentication (MFA) to reduce the risk of session compromise.
Restrict session token exposure by using secure cookies with HttpOnly and Secure flags and employing proper session management best practices.
Educate users to log out from all devices after password changes as a temporary measure.
Coordinate with HCL for timely patch deployment once available and apply updates promptly.
Conduct regular security assessments focusing on session management controls.
Consider network-level protections such as VPNs and IP whitelisting to limit session access scope.

Description

HCL Aftermarket DPC is affected by Failure to Invalidate Session on Password Change will allow attacker to access to a session, then they can maintain control over the account despite the password change leading to account takeover.

Impact

The vulnerability allows attackers to maintain unauthorized access to user accounts even after password changes, effectively bypassing a primary security control. This can lead to account takeover, unauthorized data access, and potential manipulation or disruption of services tied to the compromised accounts. For organizations, this undermines user trust and can result in data breaches, compliance violations, and operational disruptions. Since the vulnerability affects session management, it can also facilitate lateral movement within networks if the compromised accounts have elevated privileges. The medium CVSS score indicates moderate risk, but the real-world impact depends on the sensitivity of the accounts and data protected by HCL Aftermarket DPC. The lack of patches increases exposure time, and organizations relying on this product should consider compensating controls to reduce risk.
