Attack Vector: Local
Attack Complexity: High
Privileges Required: None
User Interaction: None
Scope: Changed
Confidentiality: None
Integrity: Low
Availability: None

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Local: The vulnerable component is not bound to the network stack and the attacker’s path is via read/write/execute capabilities. Either: the attacker exploits the vulnerability by accessing the target system locally (e.g., keyboard, console), or remotely (e.g., SSH); or the attacker relies on User Interaction by another person to perform actions required to exploit the vulnerability (e.g., tricking a legitimate user into opening a malicious document).
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: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
Confidentiality: None: There is no loss of confidentiality within 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: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 16 Sep 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 2026-10-26.

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

European organizations should prioritize upgrading Passwordstate to version 9.9 Build 9972 or later once patches are available. Until then, organizations should restrict local access to systems hosting Passwordstate, ensuring only trusted administrators can reach the Emergency Access web page. Network segmentation and strict access controls should be enforced to limit exposure. Monitoring and logging access to the Emergency Access page should be enhanced to detect any suspicious URL access patterns. Additionally, organizations should review and tighten Emergency Access policies, possibly disabling this feature temporarily if operationally feasible. Implementing multi-factor authentication (MFA) for administrative access and conducting regular audits of administrative activities within Passwordstate can further reduce risk. Finally, organizations should prepare incident response plans specific to credential management compromise scenarios.

Description

Click Studios Passwordstate before 9.9 Build 9972 has a potential authentication bypass for Passwordstate emergency access. By using a crafted URL while on the Emergency Access web page, an unauthorized person can gain access to the Passwordstate Administration section.

Impact

For European organizations using Passwordstate, this vulnerability could lead to unauthorized administrative access to their password management system if an attacker gains local access to the network or system hosting Passwordstate. While the attack complexity is high and requires local access, the impact on integrity is significant because an attacker with administrative access can alter stored credentials, potentially leading to further compromise of critical systems. Although confidentiality and availability are not directly impacted by this vulnerability, the integrity breach could cascade into broader security incidents, including unauthorized disclosure or denial of service through credential manipulation. Organizations with strict regulatory requirements around credential management and data protection (e.g., GDPR) may face compliance risks if such unauthorized access occurs. The lack of known exploits reduces immediate risk, but the presence of this vulnerability in a critical security tool warrants prompt attention.
