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: High: The attacker requires privileges that provide significant (e.g., administrative) control over the vulnerable system allowing full access to the vulnerable system’s settings and files.
User Interaction: Passive: Successful exploitation of this vulnerability requires limited interaction by the targeted user with the vulnerable system and the attacker’s payload. These interactions would be considered involuntary and do not require that the user actively subvert protections built into the vulnerable system.
Vulnerable system confidentiality: None: There is no loss of confidentiality within 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: None: There is no impact to availability within 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 26 Jan 2026
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

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 2026-10-25.

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

Organizations should immediately implement strict input validation and output encoding on the 'mark' parameter and any other user-supplied inputs within the Books_Manager application to prevent script injection. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. Conduct thorough code reviews focusing on input handling in add_book_check.php and related modules. If possible, isolate or restrict access to the Books_Manager application to trusted users and networks until a vendor patch is available. Educate users about the risks of clicking on suspicious links or inputs within the application. Monitor web application logs for unusual input patterns or attempted script injections. Consider deploying Web Application Firewalls (WAFs) with rules targeting XSS payloads specific to this vulnerability. Engage with the vendor or community to track patch releases and apply updates promptly once available.

Description

A vulnerability has been found in iJason-Liu Books_Manager up to 298ba736387ca37810466349af13a0fdf828e99c. This affects an unknown part of the file controllers/books_center/add_book_check.php. Such manipulation of the argument mark leads to cross site scripting. The attack can be launched remotely. The exploit has been disclosed to the public and may be used. This product does not use versioning. This is why information about affected and unaffected releases are unavailable.

Impact

This XSS vulnerability can lead to theft of sensitive user information such as session cookies, credentials, or personal data, enabling account hijacking or unauthorized actions within the Books_Manager application. It can also facilitate phishing attacks by injecting deceptive content or redirecting users to malicious sites. For organizations, this can result in data breaches, loss of user trust, and potential regulatory penalties if personal data is compromised. Since the vulnerability requires user interaction, the scope is somewhat limited but remains significant in environments where users frequently interact with the affected application. The absence of versioning and patches increases the risk of prolonged exposure. Attackers could leverage this vulnerability as an initial foothold or part of a broader attack chain, especially in organizations relying heavily on this software for book management or related workflows.

Summary

CVE-2026-1444 identifies a cross-site scripting vulnerability in the iJason-Liu Books_Manager software, affecting the add_book_check.php file, specifically through the 'mark' parameter. This vulnerability allows an attacker to inject malicious scripts that execute in the context of the victim's browser when they interact with crafted input. The flaw stems from insufficient input validation or output encoding, enabling script injection. The attack vector is network-based, requiring no authentication but user interaction to trigger the malicious payload. The vulnerability has been publicly disclosed, but no confirmed active exploitation has been reported. The software does not use versioning, making it difficult to determine all affected instances. The CVSS 4.0 vector indicates low attack complexity, no privileges required, but user interaction is necessary. The impact primarily affects confidentiality and integrity by potentially stealing session tokens or manipulating page content, with no direct availability impact.
