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: High: The attacker requires privileges that provide significant (e.g., administrative) control over the vulnerable system allowing full access to the vulnerable system’s settings and files.
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 8 Feb 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: evidence found.
CVSS exploit maturity: proof of concept public
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), CVSS vector, the Metasploit, Exploit-DB and nuclei-templates index as of 26 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.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, 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-2026-2134, organizations should implement the following specific measures: 1) Immediately restrict access to the /hms/admin/manage-doctors.php interface to trusted administrators only, using network segmentation and strong authentication controls. 2) Conduct a thorough code review and apply input validation and sanitization on the 'ID' parameter to prevent SQL injection, preferably by using parameterized queries or prepared statements in the application code. 3) Monitor logs for unusual database queries or access patterns indicative of injection attempts. 4) If available, apply vendor patches or updates addressing this vulnerability as soon as they are released. 5) Employ Web Application Firewalls (WAFs) with rules designed to detect and block SQL injection payloads targeting the affected endpoint. 6) Enforce the principle of least privilege for database and application users to limit the impact of any successful injection. 7) Conduct security awareness training for administrators to recognize and report suspicious activities. 8) Regularly back up critical data and test restoration procedures to minimize operational impact in case of data tampering or loss.

Description

A security vulnerability has been detected in PHPGurukul Hospital Management System 4.0. The affected element is an unknown function of the file /hms/admin/manage-doctors.php. Such manipulation of the argument ID leads to sql injection. The attack may be performed from remote. The exploit has been disclosed publicly and may be used.

Impact

The potential impact of CVE-2026-2134 on organizations is significant due to the sensitive nature of healthcare data managed by the PHPGurukul Hospital Management System. Exploitation could lead to unauthorized access to patient records, doctor information, and other confidential data, violating privacy regulations such as HIPAA or GDPR. Data integrity could be compromised if attackers modify or delete records, potentially affecting patient care and hospital operations. Availability impacts are limited but possible if database corruption or denial-of-service conditions occur. Since exploitation requires high privileges, the threat is mainly from insider threats or attackers who have already gained administrative access, which could facilitate lateral movement within the network. The public disclosure of the vulnerability increases the risk of exploitation attempts, especially in environments where patches or mitigations are not applied promptly. Healthcare organizations worldwide relying on PHPGurukul HSM 4.0 face risks of reputational damage, regulatory penalties, and operational disruptions if this vulnerability is exploited.
