Attack Vector: Network

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.

Exploitation evidence

Detectable: no evidence on record.

Exploited in the wildExploited: no evidence on record.

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

Organizations should immediately audit their Blogbook installations to identify affected versions, focusing on the presence of the vulnerable /post.php endpoint and the 'p_id' parameter usage. As no official patches are available, temporary mitigations include implementing web application firewall (WAF) rules to detect and block SQL Injection patterns targeting 'p_id'. Input validation and parameterized queries should be enforced if source code access is possible. Network segmentation and strict access controls can limit exposure. Monitoring logs for suspicious queries or anomalies related to /post.php is critical. Organizations should consider migrating to alternative platforms if vendor support remains absent. Regular backups and incident response plans should be updated to prepare for potential exploitation.

Description

A vulnerability was found in chaitak-gorai Blogbook up to 92f5cf90f8a7e6566b576fe0952e14e1c6736513. It has been declared as critical. Affected by this vulnerability is an unknown functionality of the file /post.php of the component GET Parameter Handler. The manipulation of the argument p_id leads to sql injection. The attack can be launched remotely. The exploit has been disclosed to the public and may be used. This product takes the approach of rolling releases to provide continious delivery. Therefore, version details for affected and updated releases are not available. The vendor was contacted early about this disclosure but did not respond in any way.

Impact

For European organizations using Blogbook, this vulnerability poses a tangible risk of data breaches, unauthorized data manipulation, and potential service disruption. Given the remote and unauthenticated nature of the exploit, attackers could compromise sensitive content, user data, or backend systems. This is particularly concerning for media, publishing, or content management entities relying on Blogbook for their web presence. Data privacy regulations such as GDPR heighten the consequences of data exposure, potentially leading to regulatory fines and reputational damage. Additionally, compromised systems could be leveraged for further attacks within organizational networks. The lack of vendor response and absence of patches exacerbate the risk, as organizations may struggle to remediate promptly.

Summary

CVE-2025-5401 is a critical SQL Injection vulnerability identified in the chaitak-gorai Blogbook software, specifically affecting an unknown functionality within the /post.php file's GET parameter handler. The vulnerability arises from improper sanitization of the 'p_id' parameter, allowing an attacker to inject malicious SQL code remotely without requiring authentication or user interaction. This can lead to unauthorized access, data leakage, data modification, or even full compromise of the underlying database. The product uses a rolling release model, which complicates pinpointing exact affected versions or patches. The vendor has not responded to disclosure attempts, and although no known exploits are currently observed in the wild, the public availability of the exploit code increases the risk of exploitation. The CVSS 4.0 score is 6.9 (medium severity), reflecting network attack vector, low attack complexity, no privileges or user interaction required, and limited impact on confidentiality, integrity, and availability. However, the potential for SQL Injection to escalate impact remains significant depending on the database and application context.
