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: 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: None: There is no loss of integrity within 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 31 Oct 2025
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 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

Immediately upgrade the Summer Pearl Group Vacation Rental Management Platform to version 1.0.2 or later, where session invalidation upon password change is implemented.
Implement additional security controls such as multi-factor authentication (MFA) to reduce the risk of session token compromise.
Monitor active sessions and provide users with the ability to view and revoke active sessions manually.
Enforce short session lifetimes and require re-authentication for sensitive operations.
Conduct regular security audits and penetration testing focused on session management controls.
Educate users on the importance of logging out from shared or public devices and recognizing suspicious account activity.
If upgrading immediately is not possible, consider implementing compensating controls such as forced logout mechanisms via custom scripts or firewall rules to invalidate sessions after password changes.
Ensure logging and alerting mechanisms are in place to detect unusual session activity or multiple concurrent sessions from different locations.

Description

Summer Pearl Group Vacation Rental Management Platform prior to v1.0.2 does not properly invalidate active user sessions after a password change. This allows an attacker with a valid session token to maintain access to the account even after the legitimate user changes their password.

Impact

For European organizations using the Summer Pearl Group Vacation Rental Management Platform, this vulnerability could lead to unauthorized persistent access to user accounts even after password changes. This undermines user trust and can result in data exposure, unauthorized booking modifications, or fraudulent transactions. The confidentiality of user information is partially compromised since attackers can maintain access without re-authenticating. The availability impact is low but could include disruption of legitimate user activities if attackers manipulate sessions. Given the platform's role in managing vacation rentals, attackers might exploit this to commit fraud, disrupt bookings, or harvest personal data, impacting business reputation and compliance with data protection regulations such as GDPR. The medium severity rating reflects these risks, emphasizing the need for timely remediation to prevent exploitation. Although no active exploits are reported, the ease of exploitation (no privileges or user interaction required) increases the risk if session tokens are compromised through other attack vectors.
