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 25 Feb 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: 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 29 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

Organizations using SourceCodester Simple and Nice Shopping Cart Script version 1.0 should immediately assess their exposure and implement the following mitigations: 1) Apply any official patches or updates from the vendor as soon as they become available. 2) If patches are not yet available, modify the /signup.php code to use parameterized queries or prepared statements for all database interactions involving user input, especially the Username parameter. 3) Implement strict input validation and sanitization to reject or escape potentially malicious characters in user inputs. 4) Employ Web Application Firewalls (WAFs) with SQL Injection detection and prevention rules to block suspicious requests targeting the vulnerable parameter. 5) Conduct thorough security testing, including automated scanning and manual code review, to identify and remediate similar injection flaws elsewhere in the application. 6) Monitor logs for unusual database query patterns or failed login attempts that may indicate exploitation attempts. 7) Educate developers on secure coding practices to prevent future injection vulnerabilities. These steps will reduce the risk of exploitation until a vendor patch is available and deployed.

Description

A vulnerability was determined in SourceCodester Simple and Nice Shopping Cart Script 1.0. This impacts an unknown function of the file /signup.php. This manipulation of the argument Username causes sql injection. The attack may be initiated remotely. The exploit has been publicly disclosed and may be utilized.

Impact

The primary impact of this vulnerability is the potential compromise of the database underlying the shopping cart application. Attackers exploiting this SQL Injection can retrieve sensitive information such as user credentials, personal data, or payment information stored in the database. They may also alter or delete data, disrupting business operations and damaging data integrity. In some cases, attackers could escalate their access within the system or pivot to other internal resources, increasing the scope of the breach. For e-commerce platforms, such breaches can lead to significant financial losses, reputational damage, regulatory penalties, and loss of customer trust. Since the vulnerability requires no authentication and can be exploited remotely, the attack surface is broad, affecting any exposed installation of the vulnerable script. The lack of known exploits in the wild currently limits immediate impact, but the public disclosure means attackers may develop exploits soon, increasing urgency for mitigation.
