CVE-2026-95683 Vulnerability Summary

CVE-2026-95683: In MISP, the Overmind event view enriches an event with its most recent attached report for preview purposes. The enrichment logic fetched the report using only the event ID as the lookup condition, without applying the report's own distribution/ACL constraints. Because MISP reports carry an independent distribution setting that can be more restrictive than the parent event's distribution, an authenticated user who had read access to the event could retrieve and view a report whose distribution explicitly excluded that user. Additionally, the query did not filter out soft-deleted reports, allowing retrieval of reports that had been administratively removed. The result is an unauthorized disclosure of threat-intelligence report content to users who should not have access under the report's own access-control policy. The vulnerability requires an authenticated MISP user with at least read access to the affected event.

Assessing the Risk of CVE-2026-95683

Access Complexity Graph

The exploitability of CVE-2026-95683 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).

Exploitability Analysis for CVE-2026-95683

No exploitability data is available for CVE-2026-95683.

Understanding AC and PR

A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.

Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.

Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.

CVSS Score Breakdown Chart

Above is the CVSS Sub-score Breakdown for CVE-2026-95683, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.

CIA Impact Analysis

Below is the Impact Analysis for CVE-2026-95683, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.

  • Confidentiality: None
    CVE-2026-95683 does not compromise confidentiality.
  • Integrity: None
    CVE-2026-95683 does not impact data integrity.
  • Availability: None
    CVE-2026-95683 does not affect system availability.

CAPEC Common Attack Pattern Enumeration and Classification

  • Exploitation of Thunderbolt Protection Flaws CAPEC-665 An adversary leverages a firmware weakness within the Thunderbolt protocol, on a computing device to manipulate Thunderbolt controller firmware in order to exploit vulnerabilities in the implementation of authorization and verification schemes within Thunderbolt protection mechanisms. Upon gaining physical access to a target device, the adversary conducts high-level firmware manipulation of the victim Thunderbolt controller SPI (Serial Peripheral Interface) flash, through the use of a SPI Programing device and an external Thunderbolt device, typically as the target device is booting up. If successful, this allows the adversary to modify memory, subvert authentication mechanisms, spoof identities and content, and extract data and memory from the target device. Currently 7 major vulnerabilities exist within Thunderbolt protocol with 9 attack vectors as noted in the Execution Flow.
