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 9 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

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-2026-2199, organizations should immediately audit and sanitize all inputs to the user-delete.php script, especially the ID parameter. Implementing parameterized queries or prepared statements is essential to prevent SQL injection. If source code access is available, refactor the vulnerable function to use secure coding practices. In the absence of official patches, consider deploying web application firewalls (WAFs) with rules to detect and block SQL injection attempts targeting the affected endpoint. Restrict access to the vulnerable script by IP whitelisting or network segmentation where feasible. Monitor logs for suspicious activity related to the user-delete.php endpoint and the ID parameter. Conduct thorough penetration testing to identify any other injection points. Finally, engage with the vendor or community for updates or patches and plan for timely application once available.

Description

A security flaw has been discovered in code-projects Online Reviewer System 1.0. The impacted element is an unknown function of the file /reviewer/system/system/admins/manage/users/user-delete.php. Performing a manipulation of the argument ID results in sql injection. The attack can be initiated remotely. The exploit has been released to the public and may be used for attacks.

Impact

The impact of CVE-2026-2199 on organizations worldwide can be significant. Exploitation allows attackers to execute arbitrary SQL commands on the backend database, potentially leading to unauthorized disclosure of sensitive information such as user credentials, personal data, or internal system details. Attackers could also modify or delete data, undermining data integrity and disrupting normal operations. The availability of the system could be affected if attackers perform destructive queries or cause database crashes. Since the vulnerability requires no authentication and no user interaction, it can be exploited remotely and at scale, increasing the risk of widespread attacks. Organizations relying on the Online Reviewer System for critical review workflows or data management may face operational disruptions, reputational damage, and compliance violations if exploited. The public availability of exploit code further elevates the threat level, as less skilled attackers can attempt exploitation.

Summary

CVE-2026-2199 identifies a SQL injection vulnerability in the code-projects Online Reviewer System version 1.0. The vulnerability resides in an unspecified function within the /reviewer/system/system/admins/manage/users/user-delete.php file, where the ID parameter is improperly sanitized. This allows an attacker to inject arbitrary SQL commands remotely without requiring authentication or user interaction. The vulnerability can lead to unauthorized access to or modification of the backend database, potentially exposing sensitive user data or enabling destructive actions such as data deletion or corruption. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and partial impacts on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). Although no exploits are currently observed in the wild, the public release of exploit code increases the likelihood of exploitation attempts. The lack of available patches or vendor advisories suggests that affected organizations must implement their own mitigations or code fixes. This vulnerability highlights the critical need for input validation and parameterized queries in web applications to prevent injection attacks.
