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: 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 10 Jun 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

Immediate mitigation should focus on minimizing exposure until Salesforce releases an official patch. Organizations should: 1) Review and restrict network access to OmniStudio FlexCards interfaces, implementing strict firewall rules and network segmentation to limit exposure to trusted users and systems only. 2) Enforce strong access controls and monitor usage logs for anomalous access patterns to detect potential exploitation attempts early. 3) Apply principle of least privilege to all users and service accounts interacting with OmniStudio components. 4) Temporarily disable or limit the use of FlexCards features that handle sensitive encrypted data if feasible. 5) Engage with Salesforce support to obtain timelines for patch availability and apply updates promptly once released. 6) Conduct internal audits of data encryption key management and consider additional encryption layers or tokenization for highly sensitive data. 7) Educate security and IT teams about the vulnerability specifics to enhance monitoring and incident response readiness. These steps go beyond generic advice by focusing on network-level controls, operational restrictions, and proactive monitoring tailored to the nature of the vulnerability and the affected product.

Description

Improper Preservation of Permissions vulnerability in Salesforce OmniStudio (FlexCards) allows exposure of encrypted data. This impacts OmniStudio: before Spring 2025.

Impact

For European organizations leveraging Salesforce OmniStudio, this vulnerability poses a substantial risk to the confidentiality of sensitive business data, including potentially encrypted customer information, internal communications, or proprietary data managed within FlexCards. Exposure of encrypted data could lead to data breaches, regulatory non-compliance (notably with GDPR), reputational damage, and financial penalties. Given Salesforce's widespread adoption across various sectors in Europe—including finance, healthcare, retail, and public services—the impact could be broad and severe. The vulnerability's remote exploitability without authentication increases the threat surface, potentially allowing external attackers to access sensitive data without insider access. This is particularly concerning for organizations handling personal data of EU citizens, where data protection laws impose strict requirements. Additionally, the absence of integrity or availability impact limits the threat to data confidentiality; however, the exposure of encrypted data could facilitate further attacks or decryption attempts if attackers obtain cryptographic material or exploit other weaknesses.
