CVE-2026-94374 Vulnerability Summary

CVE-2026-94374: MISP contains an insecure direct object reference vulnerability in the processModuleResultsData method of the Event model. When processing module results, the code iterates over EventReport entries supplied in the resolved data and saves each one. Unlike the adjacent attribute and object processing loops, the report loop did not unset the client-supplied 'id' field before calling save(). Because the MISP EventReport model's create() method does not strip the id field, an authenticated user with permission to submit module results could include an 'id' value referencing an existing report belonging to a different event. Upon save(), the ORM would update that existing row rather than insert a new one, allowing the attacker to   - read the content of another event's report by reparenting it into their own event  - overwrite the report's fields with attacker-controlled data  - change the report's event_id to redirect ownership.  This constitutes an authorization bypass through a user-controlled key, enabling cross-event data disclosure and integrity compromise. The vulnerability requires an authenticated session with the ability to invoke module result processing on an event. Version affected: <2.5.47

Assessing the Risk of CVE-2026-94374

Access Complexity Graph

The exploitability of CVE-2026-94374 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-2026-94374

No exploitability data is available for CVE-2026-94374.

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-2026-94374, 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-2026-94374, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
