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: 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: 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: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 2 Jul 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

European organizations should prioritize upgrading the OneLogin Active Directory Connector to version 6.1.5 or later once the patch is officially released. Until then, organizations should implement compensating controls such as restricting network access to the Active Directory Connector to trusted management networks and enforcing strict privilege management to limit who can interact with the connector. Monitoring and logging authentication token usage and access patterns can help detect anomalous activities indicative of exploitation attempts. Additionally, organizations should review and tighten encryption configurations and key management practices related to the DirectoryToken. Employing network segmentation to isolate identity management components and enforcing multi-factor authentication (MFA) for administrative access can further reduce risk. Regularly auditing and validating the integrity of identity connectors and tokens will help identify potential leaks early. Finally, organizations should prepare incident response plans specific to identity token compromise scenarios to minimize impact if exploitation occurs.

Description

In One Identity OneLogin Active Directory Connector before 6.1.5, encryption of the DirectoryToken was mishandled, aka ST-812.

Impact

For European organizations, this vulnerability poses a moderate risk primarily to the confidentiality of authentication tokens used in identity management. Organizations relying on OneLogin Active Directory Connector for hybrid identity environments could face unauthorized disclosure of DirectoryTokens, potentially enabling attackers to impersonate users or escalate privileges within the network. This could lead to unauthorized access to sensitive systems and data, undermining trust in identity services and potentially violating data protection regulations such as GDPR if personal data is accessed or exfiltrated. While the vulnerability does not directly impact system integrity or availability, the compromise of authentication tokens can facilitate further attacks, including privilege escalation and lateral movement, increasing the overall risk posture. Given the widespread adoption of OneLogin in enterprise environments across Europe, especially in sectors like finance, healthcare, and government, the vulnerability could have significant operational and compliance implications if exploited.
