Threat metrics

Exploit Maturity: POC

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

Attack Vector: Network: The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, 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: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system 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 Vulnerable System.
Vulnerable system 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 to the Vulnerable System.
Vulnerable system availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the Vulnerable System are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.
Exploit Maturity: POC: Based on threat intelligence sources each of the following must apply: · Proof-of-concept is publicly available · No knowledge of reported attempts to exploit this vulnerability · No knowledge of publicly available solutions used to simplify attempts to exploit the vulnerability

Exploitation evidence

Disclosed: evidence found.
CVE published 23 Mar 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: evidence found.

Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), CVSS vector, the Metasploit, Exploit-DB and nuclei-templates index as of 30 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.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), 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

To mitigate CVE-2026-4594, organizations should first identify all instances of erupt framework usage, particularly versions 1.13.0 through 1.13.3. Until an official patch is released, the following specific actions are recommended: 1) Disable or restrict the functionality that uses the geneEruptHqlOrderBy function if feasible, especially any user-controllable sorting features. 2) Implement strict input validation and sanitization on the sort.field parameter to allow only known safe field names or whitelist acceptable values. 3) Employ Web Application Firewalls (WAFs) with custom rules to detect and block suspicious HQL or SQL injection patterns targeting the vulnerable parameter. 4) Isolate database access for erupt-based applications with least privilege principles to limit potential damage. 5) Monitor database logs and application logs for unusual query patterns indicative of injection attempts. 6) Prepare incident response plans for potential exploitation scenarios. 7) Engage with the erupt community or maintainers to track patch developments and apply updates promptly once available. 8) Consider alternative frameworks or versions if mitigation is not feasible in the short term.

Description

CVE-2026-4594 is a SQL injection vulnerability in the erupt open-source framework versions up to 1.13.3. It affects the geneEruptHqlOrderBy function in the erupt-jpa module, where the sort.field argument is improperly sanitized, allowing remote attackers to inject malicious SQL via Hibernate queries. No authentication or user interaction is required to exploit this vulnerability. Although the vendor was notified, no response or patch has been issued, and public exploit details are available. The CVSS 4.0 score is 6.9 (medium severity), reflecting the potential for data exposure and integrity compromise but with limited scope and no privilege escalation.

Impact

The primary impact of CVE-2026-4594 is unauthorized access to or manipulation of database contents managed by applications using the erupt framework. Attackers can exploit the SQL injection to read sensitive data, modify records, or potentially escalate attacks to compromise the underlying database server. This can lead to data breaches, loss of data integrity, and disruption of application functionality. Since the vulnerability requires no authentication and can be exploited remotely, it poses a significant risk to publicly accessible services using affected versions. Organizations relying on erupt for critical data operations may face regulatory compliance issues, reputational damage, and operational downtime if exploited. The medium severity score reflects that while the impact is serious, the scope is limited to applications using the vulnerable function and versions. However, the public availability of exploit information increases the urgency for mitigation. The absence of a vendor patch means that the threat may persist for an extended period, increasing exposure.
