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 19 Feb 2026
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
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
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 2026-10-25.

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 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-2026-2690, organizations should immediately restrict access to the vulnerable /admin/ajax.php?action=login endpoint by implementing network-level controls such as IP whitelisting or VPN access to limit exposure. Employ web application firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting the Username parameter. Developers should audit the source code to replace vulnerable SQL queries with parameterized statements or prepared queries to ensure proper input sanitization. Until an official patch is released, consider deploying runtime application self-protection (RASP) solutions to monitor and block suspicious database queries. Regularly review logs for unusual login attempts or database errors indicative of exploitation attempts. Additionally, conduct penetration testing focused on injection vulnerabilities to identify and remediate similar issues. Finally, maintain an incident response plan to quickly address any detected exploitation.

Description

A flaw has been found in itsourcecode Event Management System 1.0. Affected by this vulnerability is an unknown functionality of the file /admin/ajax.php?action=login of the component Admin Login. This manipulation of the argument Username causes sql injection. It is possible to initiate the attack remotely. The exploit has been published and may be used.

Impact

The impact of CVE-2026-2690 can be significant for organizations using the itsourcecode Event Management System 1.0. Successful exploitation allows attackers to perform unauthorized SQL queries, potentially leading to data breaches involving sensitive user or organizational information. Attackers could bypass authentication mechanisms, gaining administrative access to the event management system, which could disrupt event operations, manipulate event data, or compromise user privacy. The integrity of stored data could be undermined, affecting trustworthiness and operational continuity. Availability may also be affected if attackers delete or alter critical data or cause database errors. Given the remote and unauthenticated nature of the exploit, the threat surface is broad, increasing the likelihood of attacks. Organizations relying on this system for event coordination, ticketing, or user management may face operational disruptions, reputational damage, and regulatory compliance issues if exploited.
