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: Low: The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
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.

Exploitation evidence

Disclosed: evidence found.
CVE published 5 Jun 2025
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 2026-10-26.

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

Since no official patches are currently available, European organizations should implement immediate compensating controls. These include: 1) Applying Web Application Firewall (WAF) rules specifically targeting SQL injection patterns on the /admin/edit-category.php endpoint and the 'description' parameter to block malicious payloads. 2) Restricting network access to the administrative interface to trusted IP addresses or VPN-only access to reduce exposure. 3) Conducting thorough input validation and sanitization on the 'description' parameter at the application level, if source code access and modification are possible. 4) Monitoring database logs and application logs for suspicious queries or anomalies indicative of SQL injection attempts. 5) Preparing for rapid patch deployment once an official fix is released by PHPGurukul. 6) Considering temporary disabling or limiting the use of the affected functionality if feasible. 7) Educating administrators about the vulnerability and signs of exploitation to enhance detection and response capabilities.

Description

A vulnerability was found in PHPGurukul Complaint Management System 2.0. It has been declared as critical. This vulnerability affects unknown code of the file /admin/edit-category.php. The manipulation of the argument description leads to sql injection. The attack can be initiated remotely. The exploit has been disclosed to the public and may be used.

Impact

For European organizations using PHPGurukul Complaint Management System 2.0, this vulnerability poses a significant risk to the confidentiality and integrity of complaint data, which may include sensitive personal or organizational information. Exploitation could lead to unauthorized data disclosure, data tampering, or disruption of complaint management processes, potentially affecting customer trust and regulatory compliance, especially under GDPR. The remote and unauthenticated nature of the attack increases the threat landscape, as attackers can exploit the vulnerability without insider access or user interaction. Organizations relying on this system for critical complaint handling may face operational disruptions and reputational damage. Additionally, if the backend database contains other integrated sensitive data, the impact could extend beyond the complaint system itself. Given the lack of patches, organizations must act swiftly to mitigate risks. The medium CVSS score suggests that while the vulnerability is serious, it may not lead to full system compromise in all cases, but the potential for data leakage or partial system control remains.
