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: 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.
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

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 2026-10-25.

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

To mitigate CVE-2025-13253, organizations should immediately audit and restrict access to the /add_librarian.php endpoint, ensuring only trusted users have access. Implement strict input validation and sanitization on the Username parameter, preferably using parameterized queries or prepared statements to prevent SQL injection. If available, apply official patches or updates from projectworlds as soon as they are released. In the absence of patches, consider deploying web application firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting this endpoint. Conduct thorough code reviews and penetration testing focused on input handling in the affected module. Additionally, monitor logs for suspicious database queries or failed injection attempts. Educate administrators and developers about secure coding practices to prevent similar vulnerabilities in future releases. Finally, consider isolating the affected system within the network to limit exposure until the vulnerability is fully remediated.

Description

A vulnerability was determined in projectworlds Advanced Library Management System 1.0. This affects an unknown part of the file /add_librarian.php. This manipulation of the argument Username causes sql injection. The attack is possible to be carried out remotely. The exploit has been publicly disclosed and may be utilized.

Impact

The primary impact of CVE-2025-13253 is unauthorized access and potential manipulation of the backend database of the Advanced Library Management System. This could lead to exposure or alteration of sensitive librarian account information and possibly other library management data. While the impact on availability is limited, the confidentiality and integrity of the system's data are at risk. Organizations using this software may face data breaches, unauthorized privilege escalation, or data corruption. Given the niche nature of the product, the overall global impact is limited but significant for affected institutions such as libraries, educational organizations, and related entities. The public disclosure of the vulnerability increases the risk of exploitation, especially by opportunistic attackers scanning for vulnerable instances. Without timely mitigation, attackers could leverage this flaw to compromise system integrity and confidentiality, potentially leading to reputational damage and operational disruptions.

Summary

CVE-2025-13253 is an SQL injection vulnerability identified in version 1.0 of the projectworlds Advanced Library Management System, specifically within the /add_librarian.php script. The vulnerability arises from improper sanitization of the Username parameter, which allows an attacker to inject arbitrary SQL commands remotely. This injection flaw can be exploited without user interaction but requires the attacker to have low privileges on the system. The vulnerability is classified with a CVSS 4.0 base score of 5.3, indicating medium severity. The CVSS vector highlights that the attack vector is network-based (AV:N), with low attack complexity (AC:L), no privileges required (PR:L), and no user interaction (UI:N). The impact on confidentiality, integrity, and availability is low to limited, but successful exploitation could allow unauthorized reading or modification of database contents. No patches or fixes have been officially released yet, and no known exploits are currently active in the wild. The vulnerability affects a specialized library management product, which may limit the scope of affected organizations but still poses a risk to institutions relying on this software for managing librarian accounts and related data. The public disclosure of the vulnerability increases the likelihood of exploitation attempts.
