Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, 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: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.
Availability: High: There is total loss of availability, resulting in the attacker being able to fully deny access to resources in the impacted component; this loss is either sustained (while the attacker continues to deliver the attack) or persistent (the condition persists even after the attack has completed). Alternatively, the attacker has the ability to deny some availability, but the loss of availability presents a direct, serious consequence to the impacted component (e.g., the attacker cannot disrupt existing connections, but can prevent new connections; the attacker can repeatedly exploit a vulnerability that, in each instance of a successful attack, leaks a only small amount of memory, but after repeated exploitation causes a service to become completely unavailable).

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 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.

What to do

AI-suggested

Immediately disable or restrict access to the admin_add.php file or the file upload functionality within the Computer Book Store application until a patch is available.
Implement strict server-side validation of uploaded files, including checking file types, sizes, and content signatures to prevent malicious files from being accepted.
Employ web application firewalls (WAFs) with rules designed to detect and block suspicious file upload attempts targeting this vulnerability.
Monitor server logs and network traffic for unusual activity related to file uploads or execution of unauthorized scripts.
Isolate the affected application environment to limit potential lateral movement in case of compromise.
Conduct a thorough security audit of all web-facing applications to identify similar vulnerabilities.
Prepare an incident response plan tailored to potential exploitation scenarios involving arbitrary file uploads.
Engage with the software vendor or community to obtain updates or patches as soon as they become available.

Description

CVE-2025-69559 is a critical file upload vulnerability in the admin_add.php component of code-projects Computer Book Store 1.0. It allows unauthenticated remote attackers to upload arbitrary files without any user interaction, leading to full system compromise. The vulnerability has a CVSS score of 9.8, indicating high impact on confidentiality, integrity, and availability. No known exploits are currently in the wild, and no patches have been published yet. European organizations using this software, especially those in countries with significant e-commerce or software development sectors, are at risk. Attackers could leverage this flaw to execute arbitrary code, steal sensitive data, or disrupt services. Mitigation requires immediate restriction of file upload functionality, implementation of strict server-side validation, and monitoring for suspicious activity.

Impact

For European organizations, this vulnerability poses a severe risk, especially those relying on the affected Computer Book Store software or similar e-commerce platforms. Exploitation could lead to unauthorized access to sensitive customer data, intellectual property theft, and disruption of business operations. The critical nature of the vulnerability means that attackers could gain full control over affected systems, potentially pivoting to internal networks and causing widespread damage. This could result in regulatory penalties under GDPR due to data breaches, reputational damage, and financial losses. The threat is particularly acute for organizations with public-facing administrative interfaces and insufficient security controls. Given the lack of patches, the window of exposure remains open, increasing the urgency for proactive defense measures.

Summary

The vulnerability identified as CVE-2025-69559 affects the Computer Book Store 1.0 software developed by code-projects, specifically within the admin_add.php script. This vulnerability is classified as CWE-434, which pertains to unrestricted file upload. The flaw allows an attacker to upload arbitrary files to the server without any authentication or user interaction, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). This means the attacker can exploit the vulnerability remotely over the network with low complexity and no privileges. The impact is critical, with full compromise of confidentiality, integrity, and availability (C:H/I:H/A:H). An attacker could upload malicious scripts or executables, leading to remote code execution, data theft, or denial of service. Although no patches or known exploits are currently reported, the high severity and ease of exploitation make this a significant threat. The vulnerability was reserved and published in early 2026, indicating it is a recent discovery. The absence of affected version details suggests the vulnerability may impact all versions of the software, or that versioning information is not publicly disclosed. The lack of patches implies that organizations must implement interim mitigations to reduce risk.

The product allows the upload or transfer of dangerous file types that are automatically processed within its environment.
Architecture and Design
Generate a new, unique filename for an uploaded file instead of using the user-supplied filename, so that no external input is used at all.
Architecture and Design · Enforcement by Conversion
When the set of acceptable objects, such as filenames or URLs, is limited or known, create a mapping from a set of fixed input values (such as numeric IDs) to the actual filenames or URLs, and reject all other inputs.
Architecture and Design
Consider storing the uploaded files outside of the web document root entirely. Then, use other mechanisms to deliver the files dynamically.
