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 12 Mar 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: 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 30 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

Immediately restrict network access to the web-based pharmacy management system, allowing only trusted internal IP addresses to connect to the administrative interface.
Implement strict role-based access controls (RBAC) and audit all administrative accounts to ensure least privilege principles are enforced.
Monitor logs for unusual activity related to add_admin.php or other administrative functions, including unexpected privilege escalations or account creations.
If possible, disable or restrict the add_admin.php functionality until a vendor patch or update is available.
Conduct a thorough security review of all authorization mechanisms within the application to identify and remediate similar flaws.
Employ web application firewalls (WAFs) with custom rules to detect and block suspicious requests targeting administrative endpoints.
Maintain regular backups of critical data to enable recovery in case of data tampering or deletion.
Engage with the vendor or community to obtain updates or patches as soon as they are released and apply them promptly.
Educate system administrators and users about the risks of unauthorized access and the importance of secure credential management.

Description

A vulnerability was identified in SourceCodester Web-based Pharmacy Product Management System 1.0. This affects an unknown function of the file add_admin.php. Such manipulation leads to improper authorization. The attack may be launched remotely.

Impact

The vulnerability allows attackers with limited privileges to bypass authorization controls and gain unauthorized administrative capabilities within the pharmacy product management system. This can lead to unauthorized access to sensitive pharmaceutical inventory data, modification or deletion of product records, and disruption of pharmacy operations. Such impacts could compromise patient safety, regulatory compliance, and business continuity. While the vulnerability does not allow full system compromise without additional flaws, the ability to escalate privileges remotely increases the attack surface significantly. Organizations worldwide using this software risk data integrity issues, potential exposure of confidential pharmaceutical information, and operational downtime. The lack of known exploits currently reduces immediate risk, but the vulnerability could be targeted in the future, especially by attackers focusing on healthcare supply chains. The medium severity rating indicates a moderate risk that should be addressed promptly to prevent exploitation.
